The two disengaging hooks are connected by a relatively tight and thin wire rope to the disengaging release clip located approximately at the center of the seaboat. The thin connecting wire rope is called the "Fore and After". The disengaging hooks are normally held safe from unintentionally dropping the seaboat by a pin in each disengaging hook. In the Royal Navy, as ship's crew starts to lower the boat, the order "Out Pins" is given.

As there is much relating to best practices B2P has focused on education and training, and the propagation of technical manuals, and footbridge building text books. Bridges to Prosperity provides the needed capital in the form of free recycled wire rope and strand. Best practice dictates that when capital is provided in this manner, that there are no unintended consequences, e.g. B2P does not provide free cable to countries where there is an existing or budding wire rope industry.

A wedge socket termination is useful when the fitting needs to be replaced frequently. For example, if the end of a wire rope is in a high-wear region, the rope may be periodically trimmed, requiring the termination hardware to be removed and reapplied. An example of this is on the ends of the drag ropes on a dragline. The end loop of the wire rope enters a tapered opening in the socket, wrapped around a separate component called the wedge.

In 1973 Sta-Lok launched the swageless terminal system for wire rope at the London Boat Show. The swageless terminal can be fitted by using hand tools, unlike a swage terminal which requires a special press, roller die or rotary hammer machine to crimp it onto a wire. This makes them very useful if the wire assembly must be made-up on site. A swageless terminal will work under constant loading and variable shock loading, making it stronger than the wire rope.

He lived at 35 Bedford Place, London, W.C. His first patent (English Patent 25,325 and U.S. Pat. No. 609,570) was granted in 1896. The principal element of the Bowden cable is a flexible tube containing a length of fine wire rope that could slide within the tube, directly transmitting pulling, pushing or turning movements on the wire rope from one end to the other without the need of pulleys or flexible joints. The cable was particularly intended for use in conjunction with bicycle brakes.

Modern wire rope was invented by the German mining engineer Wilhelm Albert in the years between 1831 and 1834 for use in mining in the Harz Mountains in Clausthal, Lower Saxony, Germany. It was quickly accepted because it proved superior to ropes made of hemp or to metal chains, such as had been used before.Modern History of Wire Rope - Donald Sayenga Wilhelm Albert's first ropes consisted of three strands consisting of four wires each. In 1840, Scotsman Robert Stirling Newall improved the process further.

Iron: An illustrated weekly journal for iron and steel, Volume 63 by Sholto Percy In America wire rope was manufactured by John A. Roebling, starting in 1841 and forming the basis for his success in suspension bridge building. Roebling introduced a number of innovations in the design, materials and manufacture of wire rope. Ever with an ear to technology developments in mining and railroading, Josiah White and Erskine Hazard, principal owners of the Lehigh Coal & Navigation Company (LC&N; Co.) -- as they had with the first blast furnaces in the Lehigh Valley -- built a Wire Rope factory in Mauch Chunk,Modern History of Wire Rope - Donald Sayenga Pennsylvania in 1848, which provided lift cables for the Ashley Planes project, then the back track planes of the Summit Hill & Mauch Chunk Railroad, improving its attractiveness as a premier tourism destination, and vastly improving the throughput of the coal capacity since return of cars dropped from nearly four hours to less than 20 minutes. The decades were witness to a burgeoning increase in deep shaft mining in both Europe and North America as surface mineral deposits were exhausted and miners had to chase layers along inclined layers.

With the parallel groove system, rope wear is considerably reduced in multilayer spooling. Winch drums for multilayer wire rope Spooling When the first layer has filled the drum, the second layer then travels back across the drum with each wrap of rope sitting precisely along the groove of two wraps of the first layer. With parallel grooving it is possible to calculate the exact forces that the rope imposes on the drum because the spooling is controlled. Multilayer wire rope Spooling Pic 1 Cross winding is reduced to approximately 20% of the circumference of the drum, and 80% remains parallel to the flanges in the inner layer rope groove. This parallel grooving evenly distributes the load between the individual layers and has been shown to increase substantially – by more than 500%, tests have shown – the life of the wire rope.

On receipt of Gordon's letter, Newall designed a wire rope machine, consisting of four strands and four wires to a strand. On Gordon's return to the UK in 1839, he formed a partnership with Robert and Charles Liddell, registering R.S. Newall and Company in Dundee. On 17 August 1840, Newall took out a patent for "certain improvements in wire rope and the machinery for making such rope." R.S. Newall and Company established a factory in Gateshead, England, and commenced making wire ropes for "Mining, Railway, Ships' Rigging, and other purposes".

However, fracture was quick, at around half a millisecond. In 1829 Wilhelm Albert had studied and reported on the failure of the iron chains and began creating a twisted metal cabling known as Albert Rope. In 1864 Andrew Smith Hallidie manufactured wire rope and was heavily involved in building early cable bridges and ropeway conveyors; his wire rope went on to be used in San Francisco's famous cable cars, and was also added to the cable drums in the hoist houses on the Comstock Lode. Another innovation, were spring loaded cages.

An aerial tramway used in mining, at the Shenandoah-Dives Mill in Silverton, Colorado The first recorded mechanical ropeway was by Venetian Fausto Veranzio who designed a bi-cable passenger ropeway in 1616. The industry generally considers Dutchman Adam Wybe to have built the first operational system in 1644. The technology, which was further developed by the people living in the Alpine regions of Europe, progressed and expanded with the advent of wire rope and electric drive. The first use of wire rope for aerial tramways is disputed.

To overcome the distance and friction limitations of line shafts, wire rope systems were developed in the late 19th century. Wire rope operated at higher velocities than line shafts and were a practical means of transmitting mechanical power for a distance of a few miles or kilometers. They used widely spaced, large diameter wheels and had much lower friction loss than line shafts, and had one-tenth the initial cost. To supply small scale power that was impractical for individual steam engines, central station hydraulic systems were developed.

"Trenton Makes, the World Takes, reads the famous red neon sign that spans a bridge between the state Capitol and Morrisville, Pa., affectionately known by locals as the Trenton Makes bridge.... In its heyday, Trenton was a world- class producer of rubber, steel, wire rope, and pottery. The cables for three famous suspension bridges – the Brooklyn, George Washington and Golden Gate – were produced here at John A. Roebling's factory." The city adopted the slogan in 1917 to represent Trenton's then-leading role as a major manufacturing center for rubber, wire rope, ceramics and cigars.

27 In 1851–1852 they produced of it. The company had a monopoly on this product, and the cores for nearly all submarine cables made before 1865 were made by them. The Gutta Percha Company never made finished cables; they supplied the cores and other companies, mostly wire rope manufacturers, laid them into the steel armouring to make complete cables. In April 1864, the Gutta Percha Company merged with Glass, Elliot and Company, one of these wire rope makers, to form the Telegraph Construction and Maintenance Company who could supply completed cables and provide maintenance for them.

Mine conveyances run on the guides in a similar way to how a steel roller coaster runs on its rails, both having wheels which keep them securely in place. Some shafts do not use guide beams but instead utilize steel wire rope (called Guide ropes) kept in tension by massive weights at shaft bottom called cheese weights (because of their resemblance to a truckle or wheel of cheese) as these are easier to maintain and replace. The largest compartment is typically used for the mine cage, a conveyance used for moving workers and supplies below the surface, which is suspended from the hoist on steel wire rope. It functions in a similar manner to an elevator.

Wire or wire rope is inserted into a channel in the Gripple wire joiner, where it is gripped by a spring-loaded roller or wedge, and tensioned by being pulled through. The channel is mirrored on the opposite side of the Gripple wire joiner, allowing a second piece of wire to be joined. By turning a Gripple wire joiner through 90 degrees and combining it with wire rope, it produces a suspension system capable of holding up substantial loads, and this has given rise to a range of Gripple suspension systems, which are sold to the construction industry worldwide. Thousands of Gripple wire joiners hold together the Great Dingo Fence in Australia, the world's longest fence.

Working steps Serving in action lift ending at the right edge of the picture) is wormed, parcelled and served, and painted, as described below. To worm, parcel and serve a line is to apply a multi-layered protection against chafe and deterioration to standing rigging. It is a technique not usually used on modern small boats, but is found extensively on traditionally-rigged sailing ships. Worming, parcelling and serving —referred to collectively as "service"— is traditionally applied only to traditional twisted rope, either natural fiber or steel wire-rope, not the braided line almost exclusively used on modern vessels, but some traditional vessels now use modern high modulus braided lines (like Amsteel or AS-90) in place of wire rope (to save weight aloft) and serve the line to maintain the traditional appearance.

The guys supporting a sailboat mast are called "standing rigging" and in modern boats are stainless steel wire rope. Guys are rigged to the bow and stern, usually as a single guy. Lateral guys attach to "chain plates" port and starboard attached to the hull. Multiple guys are usually installed with spreaders to help keep the mast straight ("in column").

The ninth match was a "Transparent Electric Explosion Deathmatch", a parody of the "Explosive Barbed Wire Rope Deathmatch" stipulation used in hardcore promotions such as Frontier Martial Arts Wrestling, in which the explosions are non-existent but where the wrestlers and the referee act as if they were real. In this match, Danshoku Dino faced Invisible Man, an "invisible wrestler" i.e. non-existent.

He also called his daughter Helen, and so it is possible that the town in Australia is actually named after her. Unfortunately in the same year as Helensburgh in Australia acquired its new name, Charles Harper was killed in a mining accident – whilst supervising the haulage of a new steam boiler, a wire rope broke and he was killed in the recoil.

These strands are effectively rewrapped along the wire in the opposite direction to their original lay. When this type of rope splice is used specifically on wire rope, it is called a "Molly Hogan", and, by some, a "Dutch" eye instead of a "Flemish" eye.Primer of Towing / George H. Reid - 3rd ed. Fig. 3-5 p30 - Cornell Maritime Press, 2004.

Transport infrastructure connects people to jobs, education, and health services; it enables the supply of goods and services around the world; and allows people to interact and generate the knowledge that creates long-term growth. Rural roads, for example, can help prevent maternal deaths through timely access to childbirth-related care, boost girls’ enrollment in school, and increase and diversify farmers’ income by connecting them to markets. The World Bank estimates that over 1 billion people do not have access to transportation networks. B2P determined that positive results could be attained by spreading the technology by building approximately 10-20 demonstration bridges per country, training locals, partnering with local technological institutes, providing downloadable & easy to use step by step photo and video manuals, and supplying free wire rope and wire rope clamps/clips for post training/demonstration programs.

The present bridge is the third bridge at the site and remains the second oldest steel bridge in the United States. In 1818, a wooden bridge was built across the Monongahela by Louis Wernwag at a cost of $102,000. This bridge was destroyed in Pittsburgh's Great Fire of 1845. The second bridge on the site was a wire rope suspension bridge built by John A. Roebling.
|
|
In 1865, he gave up bridge building in order to devote himself entirely to his wire rope manufacturing business, which was experiencing increased demand from the silver mines on the Comstock Lode. In 1867, Hallidie invented the Hallidie ropeway, a form of aerial tramway used for transporting ore and other material across mountainous districts, which he successfully installed a number of locations, and later patented.

Sir George Elliot, 1st Baronet, JP (18 March 1814 - 23 December 1893) was a mining engineer and self-made businessman from Gateshead in the North-East of England. A colliery labourer who went on to own several coal mines, he later bought a wire rope manufacturing company which manufactured the first Transatlantic telegraph cable. He was also a Conservative Party Member of Parliament (MP).

Some are also insulated at the center for feeding the RF energy at that point. Wire rope guys are frequently used and segmented with insulators at several points. Extensive lightning protection is required for insulated towers. On antennas for long-wave and VLF, the guys may serve an electrical function, either for capacitive lengthing of the mast or for feeding the mast with the radiation power.

A flexible steel wire rope is wound on the winding drum. It passes over the roller and is connected to the ladder through suitable sheaves. Steel angle sections with holes drilled to take a cross bar are fixed to the shafts for securing the ladder in a vertical position. The ladder can only be mounted when the rungs of each section are in opposition to one another.

Some famous inventions and discoveries were made in Butler County. It was in Saxonburg that the designer of the Brooklyn Bridge, John Roebling, invented his revolutionary "wire rope." At what is now known as Oil Creek, Butler County resident William Smith and Edwin Drake first proved oil could be tapped from underground for consistent supply. The Jeep was developed in Butler County by American Bantam in 1941.

192 Production was halted for a time due to a dispute with R.S. Newall and Company of Gateshead. Newall had a patent for manufacturing wire rope with a soft core to make it more flexible, and claimed that this submarine cable breached that patent. The issue was resolved by allowing Newall to take over production of the cable at Wilkins and Wetherly's Wapping premises.Smith, pp.

The word sustainability is also used widely by western country development agencies and international charities to focus their poverty alleviation efforts in ways that can be sustained by the local populace and its environment. For example, teaching water treatment to the poor by boiling their water with charcoal, would not generally be considered a sustainable strategy, whereas using PET solar water disinfection would be. Also, sustainable best practices can involve the recycling of materials, such as the use of recycled plastics for lumber where deforestation has devastated a country's timber base. Another example of sustainable practices in poverty alleviation is the use of exported recycled materials from developed to developing countries, such as Bridges to Prosperity's use of wire rope from shipping container gantry cranes to act as the structural wire rope for footbridges that cross rivers in poor rural areas in Asia and Africa.

Other methods include connecting to metal gas or water pipes where these are available, or laying a long wire rope on damp ground. The latter method is not very reliable, but was common in India up to 1868. Soil has poor resistivity compared to copper wires, but the Earth is such a large body that it effectively forms a conductor with an enormous cross-sectional area and high conductance.Wheen, p.

Chain hoists, more commonly referred to as chain motors, are the most common form of point hoist, especially with touring musical shows (e.g., rock-and-roll shows), but are relatively slow. Chain motors can be mounted at the grid to hoist a load from above, or mounted at the load to "climb" towards the grid. Point hoists using wire rope (GAC) are common, and steel band point hoists are also used.

The purchase cable is a wire rope that looks very similar to the arresting cable. They are much longer, however, and are not designed to be easily removed. There are two purchase cables per arresting cable, and they connect to each end of the arresting wire. Purchase cables connect the arresting wire to the arresting gear engines and "pay out" as the arresting wire is engaged by the aircraft.

Frequently the chains broke with catastrophic effect, so blacksmith forges were maintained beside the planes in order to facilitate repairs. It was soon found that hemp rope performed better than the chains, and all planes were converted to rope. In 1858, the hemp ropes were replaced with wire rope that had been manufactured by the Roebling company. Also during those improvements the strap iron rails were replaced with T rail.

When lifting, the rail carriage was wedged underneath to take the load. Slewing was possible all around the crane, which allowed a block to be picked up from a wagon behind the crane and moved to the front of the breakwater. The lift capacity was 15 tons, and there was enough wire rope to allow the hook to descend 26 feet below rail level. The crane was highly successful in use.

Konecranes is a Corporate spin-off of Kone, which was founded in 1910. But it was not until in 1933 when KONE Corporation started to build sizeable electric overhead traveling cranes, mainly for the pulp and paper and power industry. Three years later it started to manufacture electric wire rope hoists. In 1947 the company started to make harbor cranes and in the post-war economy the harbor cranes business line experienced strong growth.

At arbor low trim, the compensating chain is fully supported by the wall. At arbor high trim, the chain is fully supported by the arbor. Paying out at half the speed of arbor travel, a compensating chain effectively eliminates imbalance along the full path of travel. A compensating wire rope line is attached to the top and to the underside of an arbor and runs through sheaves near those for the operating line.
|
|
One end of each length is attached together. The free thick end of the compensating line is attached to the underside of the arbor and the free thin end is attached to the top. As fly pipe lowers and the arbor rises, more of the thick heavy wire rope hangs beneath the arbor and compensates for the additional weight of the fly lines. This mechanism works well with T-track counterweight systems.

Hemp rigging incorporates many nautical rigging techniques and equipment (e.g., block and tackle), and was once thought to have stemmed from the nautical rigging. However, recent research has shown that this is not the case, Counterweight rigging evolved separately from hemp rigging and generally handles scenery in a more controlled fashion. Counterweight rigging replaces the hemp rope and sandbags of rope line (hemp) rigging with wire rope (steel cable) and metal counterweights, respectively.

An attempt to sell the mine by auction was abandoned following intimidation of the auctioneers by the mine's workers. Morvah Consols was agan put up for auction on 16 February 1884, initially in one lot. Items included a 24-inch cylinder engine, a 10 ton boiler, 20 fathoms of iron pumps, 16-head stamps, horse whim, wire rope, iron chains, carpenter's shop, iron, timber, etc. There was an attempt to reopen the mine in 1929.

Poured sockets are used to make a high strength, permanent cable termination. They are created by inserting the suspender wire rope (at the bridge deck supports) into the narrow end of a conical cavity which is oriented in-line with the intended direction of strain. The individual wires are splayed out inside the cone or 'capel', and the cone is then filled with molten lead-antimony-tin (Pb80Sb15Sn5) solder.T R Barnard (1959).

Over the years important innovations, such as the Weston load brake (which is now rare) and the wire rope hoist (which is still popular), have come and gone. The original hoist contained components mated together in what is now called the built-up style hoist. These built up hoists are used for heavy-duty applications such as steel coil handling and for users desiring long life and better durability. They also provide for easier maintenance.

The driver was sited in a cabin on top of the car from which he had an uninterrupted view in all directions. An endless wire rope, pulled by a winch housed in the power house, provided the power to move the trolley across the River Mersey. The winch on the Widnes side pulled the trolley towards Widnes and Runcorn in turn. Approach roads of on the Widnes side and on the Runcorn side were built.

The rims of wire wheels (or "wire spoked wheels") are connected to their hubs by wire spokes. Although these wires are generally stiffer than a typical wire rope, they function mechanically the same as tensioned flexible wires, keeping the rim true while supporting applied loads. Wire wheels are used on most bicycles and still used on many motorcycles. They were invented by aeronautical engineer George Cayley and first used in bicycles by James Starley.

The core of the new cable, again made by the Gutta Percha Company, was to have four conductors, substantially increasing the potential traffic, and insulated with gutta-percha as before. However, the four separate insulated conductors were not laid into a single cable by the Gutta Percha Company. This task was given to a wire-rope making company, Wilkins and Wetherly, who armoured the cable with an outer layer of helically laid iron wires.Haigh, p.

Bunji, part of the Astore district, is on the left bank of the Indus River as it flows south. The Gilgit district is on the right bank of Indus. Prior to 1891, there was only a ferry service to cross the Indus, which ran between Bunji and Jaglot (then called 'Sai'). In that year, in preparation for the Hunza–Nagar Campaign, a flying bridge using wire rope was laid by Captain Aylmer of the Bengal Sappers and Miners.

Hallidie abandoned mining in 1857 and returned to San Francisco. Under the name of A. S. Hallidie & Co., he commenced the manufacture of wire rope in a building at Mason and Chestnut Streets, using the machinery from American Bar. Hallidie was also heavily involved in bridge building. During 1861–2, he constructed bridges across the Klamath River at Weitchpeck, at Nevada City, across the American River at Folsom, and across the Bear, Trinity, Stanislaus, and Tuolumne rivers.

Two years later, in 1870, John Barraclough Fell replaced it with another experimental narrow gauge railway line, dubbed the Parkhouse Tramway, named after the Parkhouse Farm west of the mines. This had a gauge of and had also a very low centre of gravity and stabilising side rollers on a central beam consisting of two trusses. It was driven by a stationary engine and endless wire rope. It could transport up to 100,000 tons per year.

Tangled wire rope and rigging elements as well as timbers from the schooner Reporter were also found mixed into King Philip's hull. After an appearance in 1985, the next time the wreck was visible was almost 22 years later, in May 2007. The subsequent construction of the Ocean Beach sewer outfall resulted in more sand being dumped onto Ocean Beach, which again buried the ship. It was exposed again in November 2010, three years after its previous appearance.

The lift lines of a counterweight rigging systems are typically a specific type of steel wire rope known as galvanized aircraft cable (GAC). Oil-free diameter, 7 x 19 strand, GAC is the most common counterweight system lift line. It has a minimum cable breaking strength of approximately . ;Line control Load-bearing lines must be safely tied off, locked, terminated and/or connected to other rigging components to ensure line control and the safety of a fly system.

The duplication was a $40.55 million project funded by the Australian Government as part of its Auslink Program. The works involved duplication of 10 km of the existing Goulburn Valley Highway between the Murchison East deviation and the proposed Shepparton Bypass, just north of Ross Road. It incorporates four at-grade intersections, frontage access roads, a rest area with full facilities, and wire rope safety barriers. The Arcadia section runs adjacent to the Calder Woodburn Memorial Avenue of Honour.

DS Seacrest had been operating in the Gulf of Thailand since 1981 for the purpose of drilling gas wells for Unocal. At the time of the incident, Seacrest had been anchored at the Platong gas field. When drilling, the ship was moored over the well site by eight anchors distributed around the ship. Each anchor weighed 30,000 pounds and was connected to the ship by wire rope cables two inches in diameter and 7,000 feet in total length.

The two drums were mounted beside each other on a common shaft, and the wire rope wound in opposite directions on each drum. So while one drum was letting the rope out and lowering a full wagon down the incline, the other drum was winding its rope in and pulling an empty wagon up the incline. Hydraulic pistons slowed the rotation of the winding drums to control the speed of the wagons.Prebble, B. (Ed.) (2008), pp. 42-43.

Since the completion of the 1942 reconstruction, its special design has compensated for slipping movements, which cannot be eliminated, even by modern engineering measures. Both piers of the viaduct are regularly reviewed to detect irregularities immediately. A monitoring device attached to the viaduct makes it possible to register even the slightest shifts. Additionally, a counterweight suspended from a wire rope provides a pulling effect on the pier heads, along the line of the railway formation towards Chur.

A-gear mechanics replace a leaf spring. Also known as arresting cables or wires, cross deck pendants are flexible steel cables which are spanned across the landing area to be engaged by the arresting hook of an incoming aircraft. On aircraft carriers there are either three or four cables, numbered 1–4 from aft to forward. Pendants are made of 1 inch (25 mm), 1-1/4 (32 mm) inch or 1-3/8 inch (35mm) diameter wire rope.

Each wire rope is made up of numerous strands twisted about an oiled hemp center core, which provides a "cushion" for each strand and also supplies cable lubrication. The cable ends are equipped with terminal couplings designed for quick detachment during replacement and are able to be rapidly detached and replaced (in about 2–3 minutes on aircraft carriers). On U.S. carriers, the arresting cables are removed and replaced after each 125 arrested landings.CV NATOPS, pp. 6–8.

Stays made from puddled iron bar were used as a cheaper alternative to copper for joining the inner and outer firebox plates of steam locomotives. The incorporated stringers gave flexibility akin to stranded wire rope and stays made of the material were therefore resistant to snapping in service. Wrought iron rivets made from iron bar typically contained stringer filaments running the length of the rivet, but filaments at right angles to the tension, particularly beneath the head, caused weakness.

March and Wright 1972, p. 100. Commencing on 1 January 1946 it was the first British airline to restart operations after the war, with a charter flight with an Auster Autocrat with a cargo of wire rope and an aircraft seat between Cardiff airport and Bristol. In 1948 Cambrian was flying in cooperation with BEA and used the de Havilland Dragon Rapide, the Autocrat and the Percival Proctor. During 1949 flights between Birmingham and Jersey were begun.

The individual wires are splayed out inside the cone or 'capel', and the cone is then filled with molten lead-antimony-tin (Pb80Sb15Sn5) solder or 'white metal capping', zinc, or now more commonly, an unsaturated polyester resin compound.

He started selling such devices to the wire rope producer R.S. Newall and Company in Dundee, of which his friend (and uncle of his later wife) Lewis Gordon was the co-owner. Newall & Co also outsourced test jobs for cables to Siemens and such enabled the new company to enter the ocean cable-laying business. The branch office became Siemens Brothers in 1858. In the 1850s, the company was involved in building long distance telegraph networks in Russia.

30 In 1947, it diversified. A new division began selling welding supplies, legging supplies, rubber products, and Bethlehem Steel wire rope while another division began producing a centrifugal juicerBrower, pp. 31 Ray Amick owned the foundry from 1965 until 1974 when manufacturing in the foundry ended. In 1972, the building was purchased by the American Victorian Museum and two years later, it was converted into a non-profit cultural center that is used by 50,000 people each year.

A drawworks is the primary hoisting machinery component of a rotary drilling rig. Its main function is to provide a means of raising and lowering the traveling block. The wire-rope drill line winds on the drawworks drum and over the crown block to the traveling block, allowing the drill string to be moved up and down as the drum turns. The segment of drill line from the drawworks to the crown block is called the "fast line".

He has been very vocal about wire rope barriers and their effectiveness as a life saving measure on country roads. He recently came under fire for his comments after the death of a truck driver in Clifton Springs where he was accused of using a fatality for political gain. However, he was soon vindicated when his views were supported by road transport groups. He was managing director of his family company, which had varied retail interests.

Porter also served as consulting engineer to John A. Roebling and Sons on the Riegelsville Bridge further downstream, a wire-rope suspension bridge. Both bridges have national significance for their unique designs and have been documented by the Historic American Engineering Record. Drawings and calculations for these bridges are among Porter's papers collected at the Northampton County Historical and Genealogical Society, the Delaware River Joint Toll Bridge Commission archives, and in Special Collections at Lafayette College's Skillman Library.

Aylmer also established a wire-rope ferry which carried hundreds of tons of grains and military stores for the campaign. In May–June 1893, a new suspension bridge across the Indus was constructed by the Maharaja Pratap Singh's government, along with a neighbouring Ramghat Bridge across the Astore River. Steel wire ropes for the suspension were imported from England (made by Roger Bullivant ). They were laced with wooden girders and attached to masonry abutments, designed to withstand strain of 500 pounds per foot.

Wire rope made from steel alloy The study of metal alloys is a significant part of materials science. Of all the metallic alloys in use today, the alloys of iron (steel, stainless steel, cast iron, tool steel, alloy steels) make up the largest proportion both by quantity and commercial value. Iron alloyed with various proportions of carbon gives low, mid and high carbon steels. An iron-carbon alloy is only considered steel if the carbon level is between 0.01% and 2.00%.

After 46 years of use, the wire rope severed on 16 February 1895. It was decided to abandon the old rope system as locomotives were now much more powerful to climb the whole tunnel incline without assistance. On 12 June 1895 passenger trains were introduced into the tunnel serving the now- demolished Riverside passenger liner terminal station at the Pier Head. From the tunnel portal at Waterloo Goods Station trains ran on the Mersey Docks & Harbour Board’s railway to the Riverside station.

Grasp's propulsion machinery provides a bollard pull (towing force at zero speed and full power) of 68 tons. The centerpiece of Grasp's towing capability is an Almon A. Johnson Series 322 double-drum automatic towing machine. Each drum carries of drawn galvanized, 6×37 right-hand lay, wire-rope towing hawsers, with closed zinc-poured sockets on the bitter end. The towing machine uses a system to automatically pay-in and pay-out the towing hawser to maintain a constant strain.

Level winders can be hydraulically or electrically driven and computer controlled, or they can be simple mechanical devices. A mechanical level winder comprises a main shaft (the lead screw) with helical screw grooving along which the rope feeder travels. The rope feeder housing includes two vertical roller bars and one horizontal roller, or alternatively a wire rope sheave. The lateral movement of the housing is generated by a chain drive sprocket ratio between drum and lead screw, as shown in the image.

It is a form of sculpture created in nature, from nature, using materials found in nature like dirt, soil, rocks, logs, branches, leaves, and water, as well as man made materials like Chain-link fencing, barbed wire, rope, rubber, glass, concrete, metal, asphalt, and mineral pigments. Ice sculpture is a form of ephemeral sculpture that uses ice as the raw material. It is popular in China, Japan, Canada, Sweden, and Russia. Ice sculptures feature decoratively in some cuisines, especially in Asia.

The new bridge would make it easier to ship bluestone, slate and lumber via the railroad. In 1870, a new bridge was funded with taxpayer's money and the Town of Lumberland in New York helped build the new Pond Eddy Bridge. The new bridge was a wire-rope suspension bridge, similar to those used by John Augustus Roebling. James D. Decker, then the Sullivan County sheriff and former Lumberland town supervisor was hired to supervise the construction of the bridge.

The Franklin Manufacturing Company was established in 1884 by Frank Johnson and Oliver Crosby in St. Paul, Minnesota. One year later Franklin Manufacturing Company changed its name to American Manufacturing Company. A wire rope clamp designed to loop wire cable without the losing the integrity of the wire was invented by Oliver Crosby in 1886. American Manufacturing Company invented further enhancements to the construction industry by establishing steam-powered hoists in 1889 and the largest electric hoists, up to 15 hp.

There was a steel tramline constructed right into the bush, and there were facilities, which no other mill possessed. The plant was close to the railway line on the top of the Mamaku divide, with the easiest hauling conditions. There were two log haulers, two miles of wire rope, two locomotives, one of which has only recently been placed there, and twenty-six cottages from which revenue to the extent of £5oo a year in the shape of rentals was drawn.

The cable is now 200 m of thin multi-core containing one coaxial and 5 single wires. As it is not load-bearing, a rope still has to be used and 9 mm static climbing rope was found to be better than anything thinner, including wire rope, at preventing twist. The rope often becomes tangled with the cable, so I.A.Recordings is still looking for a weight-bearing cable. The 180 degree tilt range allows the underside of shaft caps to be inspected.

In New Zealand, there are few 2+1 roads, although regular isolated 'passing lanes' exist frequently throughout the country, mainly in heavy trafficked areas and on hills. A trial of a 2+1 road with wire-rope median barrier was undertaken on SH1 between Longswamp and Rangiriri south of Auckland, and there are plans to introduce more 2+1 roads. NZ research also investigated design and operational effects of 2+1 roads to establish the most appropriate configurations for the country.

Mono-ha (もの派) is the name given to an art movement led by Japanese and Korean artists of 20th-century. The Mono-ha artists explored the encounter between natural and industrial materials, such as stone, steel plates, glass, light bulbs, cotton, sponge, paper, wood, wire, rope, leather, oil, and water, arranging them in mostly unaltered, ephemeral states. The works focus as much on the interdependency of these various elements and the surrounding space as on the materials themselves.

Since the 1980s, ropes course sophistication has evolved considerably. Modern ropes courses incorporate sophisticated belay and safety systems using wire rope, friction devices, and climbing harnesses to manage what before were unmanaged risks. Recent technological advances in pole hardware and climbing equipment along with industry-accepted installation and design practices have greatly reduced the risk to end users and to the natural environment. Modern courses make use of a variety of materials other than trees, including utility poles and steel structures.

Figure 4. An insulating link being used on a crane Insulating links are needed on cranes and tag lines, (guide ropes), to protect against electric current passing from the power line through the wire rope of the crane and into the personnel working on or near the crane, figure 4. Figure 5 shows the Federal requirements for working close to a power line. The list includes layers of prevention but the only meaningful protection is the insulating link and tag line insulators.

The Lindis had a web camera installed in 2018 to help ensure traffic controllers and maintenance crews can monitor the highway as well as informing travellers so they are prepared for road conditions. Vehicle crashes on the Lindis Pass have occurred regularly. There is no cell phone coverage on the Lindis Pass. The New Zealand Transport Agency has upgraded aspects of state highway 8 over Lindis Pass by installing new wire-rope safety barriers, improving signage and installing electronic speed warnings in 2013.

Andrew Smith Hallidie (March 16, 1836 – April 24, 1900) was the promoter of the Clay Street Hill Railroad in San Francisco, USA. This was the world's first practical cable car system, and Hallidie is often therefore regarded as the inventor of the cable car and father of the present day San Francisco cable car system, although both claims are open to dispute. He also introduced the manufacture of wire rope to California, and at an early age was a prolific builder of bridges in the Californian interior.

Tarring rope aloft in the rigging of a sailing ship Tarring Is protecting some types of natural fibre and wire rope by coating it with tar. Hemp rope, which was typically used for standing rigging, requires tarring. Manila and cotton ropes were used for running rigging and were not tarred as this would make the rope too stiff to run easily through blocks. Regular tarring at sea was required when sailing ships used hemp rope - once every 6 months for a ship on a long voyage.

Raymond, under the ring name Josh Abercrombie, debuted for Ian Rotten's Independent Wrestling Association Mid-South promotion on October 23, 2003 in a match against Steve Stone. He continued competing across Midwestern independent promotions before returning to IWA Mid-South in October 2004. Between January and February in 2005, he began a feud against Ian Rotten, which included a match that Rotten won as part of the NWA Indiana State Championship tournament. The feud culminated in a barbed wire rope match the next day.

Examples of manually wrapped Western Union splices Wire wrapped backplane of an IBM 1401 computer, introduced in 1959 Wire wrapping comes from the tradition of rope splicing. Early wire wrapping was performed manually; a slow and careful process. Wire wrapping was used for splices and for finishing cable ends in suspension bridge wires and other wire rope rigging, usually with a smaller diameter wire wrapped around a larger wire or bundle of wires. Such techniques were purely mechanical, to add strength or prevent fraying.

Since the 1980s many of Retford's long-established companies such as Jenkins Newell Dunford (engineering) and Bridon Ropes (wire rope) have closed, with the economy becoming more services-based. Strong transport links mean that many Retford workers commute to neighbouring towns and cities; some commute to London. Retford has a strong economy mainly consisting of services with some light industry. The town itself is an important commercial centre for the local area, with large supermarkets, many independent shops and a market every Thursday, Friday and Saturday.

A cable barrier separating lanes on a 2+1 road in Sweden. A cable barrier, sometimes referred to as guard cable or wire rope safety barrier (WRSB), is a type of roadside or median safety traffic barrier/guard rail. It consists of steel wire ropes mounted on weak posts. As is the case with any roadside barrier, its primary purpose is to prevent a vehicle from leaving the traveled way and striking a fixed object or terrain feature that is less forgiving than itself.

Grooved shape steel segments were simply welded or screwed to existing plain steel drums.George F LeBus, US Patent 2204938 Ever since then, drum groovings have been widely used to guide the spooling of wire rope onto and off winch drums. Introducing a continuous helical groove onto the drum, like the thread of a screw, provides a way to guide the rope when spooling onto or off a drum. However this has been shown to work effectively only when the rope is wrapped in a single layer.

On Christmas Eve 1852 a hurricane broke off one of the minute hands of the clock. New cast iron clock dials, in diameter were presented by Henry Smith to the church in 1872 at a cost of £66 (). A new clock was installed by G. & F. Cope in 1881 which had a Denison Remontoire, compensation pendulum and wire rope lines. The strike was provided by a hammer on the hour bell on E. This was replaced by an electrically driven clock by Smiths of Derby in 1965.

During the Great Depression, one of Vancouver's several hobo jungles sprang up on the False Creek flats opposite Granville Island's north shore. "Shackers" lived on the island, in town, or in floathouses, and survived by fishing and beachcombing and sold salmon, smelt, and wood door to door or at the public market on Main Street. They were basically self-sufficient and were left alone. During the Second World War, Wright's Canadian Ropes on the island was Canada's biggest manufacturer of heavy-duty wire rope.

Atomizer coils made of kanthal usually have resistances that vary from 0.4Ω (ohms) to 2.8Ω. Coils of lower ohms have increased vapor production but could risk fire and dangerous battery failures if the user is not knowledgeable enough about electrical principles and how they relate to battery safety. Wicking materials vary from one atomizer to another. "Rebuildable" or "do it yourself" atomizers can use silica, cotton, rayon, porous ceramic, hemp, bamboo yarn, oxidized stainless steel mesh and even wire rope cables as wicking materials.

Chain- stayed bridge by the Renaissance polymath Fausto Veranzio, from 1595/1616. Prior to industrial manufacture of heavy wire rope (steel cable), suspended or stayed bridges were firstly constructed with linked rods (chain). Cable-stayed bridges date back to 1595, where designs were found in Machinae Novae, a book by Croatian-Venetian inventor Fausto Veranzio. Many early suspension bridges were cable-stayed construction, including the 1817 footbridge Dryburgh Abbey Bridge, James Dredge's patented Victoria Bridge, Bath (1836), and the later Albert Bridge (1872) and Brooklyn Bridge (1883).

Once the bridges were in place, the RE had to provide protection for them. In conjunction with the Royal Navy, they constructed booms across the river to prevent the enemy floating boats or mines downstream to damage the bridges. In XXX Corps' sector, 18th GHQTRE was instructed to build two 'Arrow' booms devised by the engineers of US Seventh Army. However, the RE had problems with this design, and instead stretched one of steel wire rope and Jerricans across the river well upstream of Rees.

It was generally known as the Village incline, and a stone bridge carried the minor road to the hamlet of Dolrhedyn over the lower section. There was a section of stone and earth embankment, and then a shallow rock cutting before the drumhouse was reached. This consisted of a drum which was long and in diameter, but little else, as there was no shelter for the brakesman who controlled its operation. The length of the wire rope differs wildly in different sources, ranging from to .

The first Munck manufacturing plant was completed in 1946, and the number of employees increased rapidly from 30 to 300 people. This was mainly as a result of an order for 18 units of trolley buses for Bergen Sporvei - the local bus company, but also orders from several other bus companies in Norway. During this time, the first Munck electric wire rope hoist was designed, and full production commenced, involving hoists and industrial cranes for all major types of industry on shore as well as onboard ships.

Boats were raised in a wheeled cradle up a slope of 1:10. The cradle was attached to the turbine by a substantial wire rope, after breakages of the original rope. The Ilminster tunnel was wide, allowing boats travelling in opposite directions to pass, but the tunnels at Lillesdon and Crimson Hill were only wide enough for one boat. However the Crimson Hill Tunnel has a double width "passing area" about halfway through its course to allow passing of the boats from either direction.

Unusually it had rear wheel drive, like the Medium Mark A Whippet and Vickers Medium Mark I and Vickers Medium Mark II. The 9th (IX) Brigade RFA took delivery of the supply variant in August 1922: subsequently two more prototypes were built, named the Vickers Dragon Nos. 1 & 2 Artillery Tractor (experimental). Whereas the Light Infantry and Tropical Tanks used a novel wire rope suspension, the prototype Dragons had conventional coil suspension based on the Vickers Medium Mark I, with 11 small road wheels and 6 return rollers.

Sky Tower & Sky Jump/Sky Cabin Sky Tower with the illuminated "K" in logo script at the top was built to support two attractions, the Parachute Sky Jump (now closed) and the Sky Cabin. Parachute Sky Jump boarded one or two standing riders anticipating the thrill of the drop into baskets beneath a faux parachute canopy. From the top, eight arms supported the vertical cable tracks of wire rope which lifted the baskets. The Sky Cabin ringed the support pole with a single floor of seats that are enclosed behind windows.

The first greyhound track to be constructed in the city of Sheffield would be called Darnall Stadium. The site chosen was the Wellington Grounds which was partly surrounded by garden allotments at the time of the greyhound track construction. The stadium would be accessed from Poole Road with the eastern side of the stadium adjacent to allotments and James Street. Directly to the north was a metal wire rope works and railway line and to the east was another large collection of allotments that would eventually be converted into the Parkway market.

Another was built in 2004 and offered visitors and fishermen alike a much safer passage to the island. The current wire rope and Douglas fir bridge was made by Heyn Construction in Belfast and raised early in 2008 at a cost of over £16,000. There have been many instances where visitors, unable to face the walk back across the bridge, have had to be taken off the island by boat. On 24 May 2017, a routine inspection revealed that the bridge's structural ropes had been damaged overnight in an act of vandalism.

Hot-dip galvanizing deposits a thick, robust layer of zinc iron alloys on the surface of a steel item. In the case of automobile bodies, where additional decorative coatings of paint will be applied, a thinner form of galvanizing is applied by electrogalvanizing. The hot-dip process generally does not reduce strength on a measurable scale, with the exception of high-strength steels (>1100 MPa) where hydrogen embrittlement can become a problem. This deficiency is a consideration affecting the manufacture of wire rope and other highly stressed products.

This new lumber could be nailed together by farmers and settlers who used it to build homes and barns throughout the western prairies and plains. Wisconsin-born, Chicago-trained Sullivan apprentice Frank Lloyd Wright designed prototypes for architectural designs from the commercial skylight atrium to suburban ranch house. German-born Pennsylvania immigrant John A. Roebling invented steel wire rope, a pivotal part of suspension bridges he designed and whose construction he supervised in Pittsburgh, Cincinnati and Buffalo, based on earlier successful canal aqueducts. His most famous project was the Brooklyn Bridge.

Due to its extreme depth, and almost circular profile, Lake Tazawa was considered to be either a caldera lake caused by volcanic activity or a crater lake caused by a meteorite impact. The depth of the lake was first measured as 397 meters, using a hemp rope, by Japanese geologist Tanaka Akamaro in 1909. The Akita Prefectural Fisheries Experiment Station survey indicated a depth of 413 meters in 1926 using a wire rope. During a three-year survey from 1937-1940, geologist Yoshimura Nobuyoshi surveyed the lake bottom, finding the deepest point to be .

Handbrakes were applied to these vehicles. The train staff in the possession of the engine crew apparently was returned to the instrument in the signal box at this time, and all vehicles were within the confines of the home signals. After a number of attempts to fit a tailrope, the brake van had been shunted back, foul of the clearance point for the loop line. The two opposing vehicles at the separation were finally hitched with a single wire rope connection, but the airbrake hoses could not be connected.

Lashing systems secure containers to the ship using devices made from wire rope, rigid rods, or chains and devices to tension the lashings, such as turnbuckles. The effectiveness of lashings is increased by securing containers to each other, either by simple metal forms (such as stacking cones) or more complicated devices such as twist-lock stackers. A typical twist-lock is inserted into the casting hole of one container and rotated to hold it in place, then another container is lowered on top of it.Peck and Hale, 2000, p. 12.

Stranded vessels can be retracted from a beach or reef by the use of Grasp's towing machine and propulsion. Additional retraction force can be applied to a stranded vessel through the use of up to six legs of beach gear, consisting of 6,000 pound STATO anchors, wire rope, chain, and salvage buoys. In a typical configuration, two legs of beach gear are rigged on board Grasp, and up to four legs of beach are rigged to the stranded vessel. In addition to the standard legs of beach gear, Grasp carries 4 spring buoys.

The stern was strengthened at critical points, new bulwark fairings were added, and an H-bitt was installed through which cabling is threaded to keep it centered during towing operations. Also installed was a hydraulic towing winch, referred to as a double-drum waterfall winch, holding or more of wire rope on each drum. One drum supports booster retrievals while the other is devoted to external tank towing. Freedom Star had been used to support scientific research operations including research for the National Oceanic and Atmospheric Administration and several universities.

This type of bridge is known as a rope bridge due to its historical construction from rope. Inca rope bridges still are formed from native materials, chiefly rope, in some areas of South America. These rope bridges must be renewed periodically owing to the limited lifetime of the materials, and rope components are made by families as contributions to a community endeavor. Simple suspension bridges, for use by pedestrians and livestock, are still constructed, based on the ancient Inca rope bridge but using wire rope and sometimes steel or aluminium grid decking, rather than wood.

Typically, a lift line runs from the sand bag (counterweight) assigned to a specific line set, up to "a single loft block" above the fly floor and back down to the fly floor. A trim clamp or a "Sunday" (a circle of wire rope) is used to attach this sandbag to the "line set" to balance the load placed on the batten. The sandbags are usually filled to weigh slightly less than the load, making the line set "Batten Heavy". When the flyman wishes to fly a batten (scenery or lights) "In" (i.e.

In a typical counterweight fly system, an arbor (carriage) is employed to balance the weight of the batten and attached loads to be flown above the stage. The arbor, which carries a variable number of metal counterweights, moves up and down vertical tracks alongside an offstage wall. In some lower-capacity fly systems, cable guide wires are used instead of tracks to guide the arbors and limit their horizontal play during vertical travel (movement). The top of the arbor is permanently suspended by several wire rope lift lines, made of galvanized steel aircraft cable (GAC).
|
|
Swage (compression) fittings or cable clips are used to terminate counterweight system lift lines, after the cable has been looped around a thimble. Cable clips terminations maintain less load capacity than swage fittings, typically require three clips, and are greatly reduced in load capacity if the installer happened to "saddle a dead horse". Both swage and cable clip terminations permanently crimp (deform) the wire rope. Trim chains and shackles, or turnbuckles and pipe clamps, typically connect the lift lines of a line set to the batten they support.
|
|
To address this issue, a compensating mechanism may be added to the counterweight system. Either chain or thick wire-rope may be used. One end of a compensating chain (typically roller chain) is suspended from the underside of the counterweight arbor, the opposite end mounted to the adjacent wall, at a point corresponding to half the travel of the arbor. The compensating chain is about half the length that the arbor travels, and sized to weigh twice as much as the combined weight of the lift lines per linear foot.

The U.S. post office established a branch there during June 1890, officially dubbing the settlement Carpenter, Colorado. One of Carpenter's first improvements was the installation of a gravity powered tramway (known as a funicular) at each of the mines. Cars traveled the incline between the mine adit and coal tipple on three rail tracks (except at the passing point, where four rails were used). The mechanics of the trams were simple; one end of a wire rope was attached to the car at the mine and the other end to the car at the tipple.

The winding engine The winding house at the Museum is a replica based on the one that used to stand at Amblecote Colliery No.2 Pit. At the back of the building is the large drum which holds the wire rope that runs over the wheel at the top of the head frame and lifts the cage. This drum is rotated by a Steam engine inside the engine house. The steam to power the engine would have come from the Egg-ended boiler in front of the engine house.

Some of the tree canopies are more than in height. Built with wire rope, aluminium ladders, wooden planks, it is secured by a series of netting for safety purposes. An additional viewing platform that will allow visitors to climb into the canopy without braving the canopy walkway is currently under construction. The Canopy Walkway was built by two Canadian engineers from Vancouver with the assistance of five (5) Ghanaians - the latter (staff of Ghana Heritage Conservation Trust- managers of the Kakum National Park Visitor Centre)have been maintaining the facility ever since.

A hydraulic riser tensioner consists of a hydraulic cylinder with sheaves at both sides. The cylinder is connected to a number of high-pressure gas bottles via a medium separator. A wire rope is rigged in the cylinder; one end is connected to the fixed part of the tensioner, the other end is connected to the riser. Fundamentals of Marine Riser Mechanics: Basic Principles and Simplified Analysis, Charles P. Sparks, On board a drill rig tensioners are usually required for drill string compensator, riser tensioner, and guideline tensioner.

The bridge was built using the Ordish–Lefeuvre system, an early form of cable-stayed bridge design which Ordish had patented in 1858. Ordish's design resembled a conventional suspension bridge in employing a parabolic cable to support the centre of the bridge, but differed in its use of 32 inclined stays to support the remainder of the load. Each stay consisted of a flat wrought iron bar attached to the bridge deck, and a wire rope composed of 1,000 diameter wires joining the wrought iron bar to one of the four octagonal support columns.

MacDermot says January 1849 (page 330). There were china clay workings on Hendra Downs, high above St Dennis on the east, and for the time being the intended connection there was not made. There were three tunnels on the line; one on the incline to Newquay Harbour, one at Coswarth—at 44 yards (40 m) in length, really a bridge—and Toldish Tunnel, 500 yards (460 m) in length. The incline from Newquay Harbour was at 1 in 4.5 and was worked by stationary engine and wire rope.

Historically, wire rope evolved from wrought iron chains, which had a record of mechanical failure. While flaws in chain links or solid steel bars can lead to catastrophic failure, flaws in the wires making up a steel cable are less critical as the other wires easily take up the load. While friction between the individual wires and strands causes wear over the life of the rope, it also helps to compensate for minor failures in the short run. Wire ropes were developed starting with mining hoist applications in the 1830s.

|
When the wire rope is terminated with a loop, there is a risk that it will bend too tightly, especially when the loop is connected to a device that concentrates the load on a relatively small area. A thimble can be installed inside the loop to preserve the natural shape of the loop, and protect the cable from pinching and abrading on the inside of the loop. The use of thimbles in loops is industry best practice. The thimble prevents the load from coming into direct contact with the wires.

The material consisted of 1800 tons of rails and fastenings, 6000 sleepers, 600 loads timber, and about 3000 tons of other material and machinery, consisting of fixed engines, cranes, pile engines, trucks, wagons, barrows, blocks, chain- falls, wire- rope, picks, bars, capstans, crabs, and a variety of other plant and tools; besides sawing machines, forges, carpenters' and smiths' tools, &c.; This material was distributed over the different vessels in such a manner that should any one or two vessels be lost disabled, it will not endanger the efficiency of the whole.

When it was time to move the shovel he took care of that as well. A cranesman, who sat on the left-hand side of the boom, controlled the crowd engine, which allowed him to set the depth of the cut and release the bucket's contents when it was full by tugging on a wire rope attached to it. In the rear was an engineer who tended the boiler and a fireman who shoveled the coal. Outside the shovel a crew of four took up and laid the track along which its flanged wheels moved.

Roebling remembered an article he had read about wire ropes. Soon after, he started developing a 7-strand wire rope at a ropewalk that he built on his farm. In 1844 Roebling won a bid to replace the wooden canal aqueduct across the Allegheny River with the Allegheny Aqueduct. His design encompassed seven spans of 163 feet (50 m), each consisting of a wooden trunk to hold the water, supported by a continuous cable made of many parallel wires, wrapped tightly together, on each side of the trunk.

These platforms have hulls (columns and pontoons) of sufficient buoyancy to cause the structure to float, but of weight sufficient to keep the structure upright. Semi-submersible platforms can be moved from place to place and can be ballasted up or down by altering the amount of flooding in buoyancy tanks. They are generally anchored by combinations of chain, wire rope or polyester rope, or both, during drilling and/or production operations, though they can also be kept in place by the use of dynamic positioning. Semi-submersibles can be used in water depths from .

Older rigging is also the source of problems since the older the rigging is the more likely corrosion has damaged the integrity of metals. Stainless steel rigging in particular has been cited as being problematic since out strands of a wire rope might appear to be fine while at the same time inner strands are compromised. For this reason many insurance companies insist that rigging holding the mast upright, termed the standing rigging, must be replaced every 10 years. Heeling characteristics of the sailing vessel are also a contributing factor.

The sterns were strengthened at critical points, new bulwark fairings were added, and an H-bitt was installed through which cabling is threaded to keep it centered during towing operations. A hydraulic towing winch was also installed, referred to as a double-drum waterfall winch, holding 2,000 feet or more of wire rope on each drum. One drum supports booster retrievals while the other is devoted to external tank towing. The ships have also occasionally been used to support scientific research operations including research for the National Oceanic and Atmospheric Administration and several universities.

Another stuntman was injured by a hydraulic puller during a shot in which Neo was slammed into a booth. The office building in which Smith interrogated Morpheus was a large set, and the outside view from inside the building was a large, three story high cyclorama. The helicopter was a full- scale light-weight mock-up suspended by a wire rope operated a tilting mechanism mounted to the studio roofbeams. The helicopter had a real minigun side-mounted to it, which was set to cycle at half its regular (3000 rounds per min) firing rate.

Cable is very strong in tensile strength, with a breaking strength in excess of 1000 lbs for these types of uses, and is a suitable in-fill material for a railing ("guard" in ICC codes). Typical diameters are 1/8", 3/16" for residential and 3/16" and 1/4" for commercial applications. There are many different types cable and strand (also referred to as wire rope). Cable and strand is available in galvanized carbon steel, type 304 stainless steel, or the highly corrosion resistant, type 316 stainless steel (best for coastal areas).

The term 'wire' is also used more loosely to refer to a bundle of such strands, as in "multistranded wire", which is more correctly termed a wire rope in mechanics, or a cable in electricity. Wire comes in solid core, stranded, or braided forms. Although usually circular in cross-section, wire can be made in square, hexagonal, flattened rectangular, or other cross-sections, either for decorative purposes, or for technical purposes such as high-efficiency voice coils in loudspeakers. Edge-wound coil springs, such as the Slinky toy, are made of special flattened wire.

The Maheno beached The hulk of Maheno in 2007 The hulk of Maheno in 2013 At the end of its commercial life, on 3 July 1935 Maheno left Sydney under tow by the 1,758 ton ship Oonah, a former Tasmanian Steamers Pty. Ltd. Bass Strait ferry, built in 1888, which along with the Maheno had been sold to the shipbreaker's yard Miyachi K.K.K. in Osaka, Japan. The ships were linked by a wire rope. On the afternoon of 7 July, about 50 miles from the coast, the towline parted in a cyclone.

The track was the first laid on the territory of Hawaii. The long mainline began at the northern end of Aalona Street in Kilauea and led southwards over Kolo Road onto Pukalani Square. It crossed the Kuhio Highway and headed then southwards along Kuawa Road, crossed Waiuli Dam and crossed the Puukumu Stream for a total of . The second, also long line led from the sugar mill to Kahili Landing, where the packaged, ground sugar was loaded onto the steamers anchored at Mo'ko'lea Point using a wire rope winch.

Dolphins typically consist of a number of piles driven into the seabed or riverbed, and connected above the water level to provide a platform or fixing point. The piles can be untreated wood, pressure treated pine wood poles, or steel or reinforced concrete beams, blocks or tubes. Smaller dolphins can have the piles drawn together with wire rope, but larger dolphins are typically fixed using a reinforced concrete capping or a structural steel frame. Access to a dolphin may be via a pedestrian bridge in the case of mooring dolphins, but is usually by boat.

The door was designed to prevent surging in the well while the ship was underway but did not seal the opening. In stowed position the array was held by supports with stabilizers to prevent motion of the array while stowed. When deployed the array was supported by wire rope attached to cable machinery located in forward holds running over winches located on deck fore and aft of the well and supersturcture. The supporting cables and the electrical cables ran over special roller devices designed to dampen ship motion that would be transferred to the deployed array.

When the Bagnalls first arrived in Turua and wanted to go to church in Thames, they rowed to Kopu then walked the last to Thames. At Orchard (now called Ngatea), Pipiroa, Kopu and Paeroa there were punts (floating platforms) that carried people, horses and carts across the rivers for a small fee. At Te Aroha, there was a wire rope stretched across the river which originally had a Māori canoe tied to it on which people could pull themselves across and was later replaced by a punt with a crank and for two shillings people could crank themselves across.

Tools are sometimes employed in the finishing or untying of a knot, such as a fid, a tapered piece of wood that is often used in splicing. With the advent of wire rope, many other tools are used in the tying of "knots." However, for cordage and other non-metallic appliances, the tools used are generally limited to sharp edges or blades such as a sheepsfoot blade, occasionally a fine needle for proper whipping of laid rope, a hot cutter for nylon and other synthetic fibers, and (for larger ropes) a shoe for smoothing out large knots by rolling them on the ground.

Directly to the North of the station sidings served the Wilkins Wire Rope Company later known as the Birnam Products subsidiary of Tinsley Wire Industries which, as of 2009, is owned by Magna International, manufacturing car seats. Directly to the West of the station a branch line left the railway on the south side of the track which once served the Eastwood Colliery. Both the branch line and the main line passed under a substantial three span bridge which carried Mill Lane (more recently known as Newmanleys Road) over the railway. When this colliery was closed the branch was used as a siding.

Then they had made a second attempt on Mr. Simons' orders, leading to the ship getting stuck with 35 m of the stern sticking out into the Nieuwe Maas. In the evening of the 15th the wreck was secured to shore by a wire rope and all tugboats except Drenthe had left. Two hours after high tide the wreck then suddenly started to move on its own and to descend the Nieuwe Maas. The crew on the wreck succeeded in letting the anchor slip out, and Drenthe succeeded in connecting again, but it had traveled some distance before the ship stopped near Vlaardingen.

Ever since the development of wire rope, comprising multiple wire strands, spooling the wire has presented technical challenges. When wrapped in multiple layers, the upper layers have a tendency to crush the lower layers, while the lower layers have a tendency to pinch upper layers. The rubbing of rope against rope also has a tendency to cause wear. These problems were addressed by Frank L. LeBus Sr., a supplier of drilling equipment to the oilfields of Texas, USA, who in 1938, patented the use of a groove bar on hoisting drums to guide the spooling of rope.

The term long products may include hot rolled bar, cold rolled or drawn bar, rebar, railway rails, wire, rope (stranded wire), woven cloth of steel wire, shapes (sections) such as U, I, or H sections, and may also include ingots from continuous casting, including blooms and billets. Fabricated structural units, such bridge sections are also classed as long products. The definition excludes "Flat Products" - slab, plate, strip and coil, tinplate, and electrical steel; and also excludes certain tubular products including seamless and welded tube. Long products find general use in construction industries, and in capital goods sectors.

Stereoscopic views of the construction of the Manhattan tower After the caissons were completed, piers were constructed on top of each of them upon which masonry towers would be built. The towers' construction was a complex process that took four years. Since the masonry blocks were heavy, the builders transported them to the base of the towers using a pulley system with a continuous -diameter steel wire rope, operated by steam engines at ground level. The blocks were then carried up on a timber track alongside each tower and maneuvered into the proper position using a derrick atop the towers.

Hobart Disc jockey and resident of Bagdad, Bob Cooke has said locals live in "mortal fear" driving down Constitution Hill - A semi-mountainous stretch of the highway. In response to some of these concerns, the Midlands Highway at Constitution Hill is being upgraded to have oncoming lanes separated by a wire rope safety fence and is expected to be completed in May 2009. The University of Tasmania is currently spending ten thousand dollars a month subsidising bus travel for students between the Hobart and Launceston Campus. This subsidy started after four students died in a car accident on the Midland Highway in 2006.

After six months in Ecuador, Toni returns to Switzerland and begins his studies of civil engineering at the Federal Institute of Technology in Zurich. However, seven weeks later he decides to leave university and return to Ecuador to help immediately. Toni with Walter Yánez In the Amazon region of Ecuador he puts together a system for building bridges with the communities, requiring almost no money: the villagers bring stone and sand, the hard wood and their labour. Toni asks for donations of used wire rope from the oil drilling rigs in the region and for scrap pipe from the national oil company Petroecuador.

Other power steering systems (such as those in the largest off-road construction vehicles) have no direct mechanical connection to the steering linkage; they require electrical power. Systems of this kind, with no mechanical connection, are sometimes called "drive by wire" or "steer by wire", by analogy with aviation's "fly-by-wire". In this context, "wire" refers to electrical cables that carry power and data, not thin wire rope mechanical control cables. Some construction vehicles have a two-part frame with a rugged hinge in the middle; this hinge allows the front and rear axles to become non-parallel to steer the vehicle.

He found agrarian work unsatisfactory, and in 1837, after the death of his brother and the birth of his first child, he returned to engineering. Roebling first signed on as a surveyor for the Beaver River canal system, launching his career with a string of canal and railroad projects. Aside from writing articles in engineering journals, Roebling designed his own wire cables and started his own company to manufacture them; the John A. Roebling Company was the first wire rope manufacturer in the United States. Gradually gaining fame for his civil engineering, Roebling finally got to build suspension bridges.

The wire ropes are stressed by fluctuating forces, by wear, by corrosion and in seldom cases by extreme forces. The rope life is finite and the safety is only ensured by inspection for the detection of wire breaks on a reference rope length, of cross-section loss, as well as other failures so that the wire rope can be replaced before a dangerous situation occurs. Installations should be designed to facilitate the inspection of the wire ropes. Lifting installations for passenger transportation require that a combination of several methods should be used to prevent a car from plunging downwards.

In centuries past, a ship's rigging was typically fashioned from rope. In the 19th century this was commonly referred to as Manilla, a reference to the origin of much good quality rope. Traditionally the running rigging was easily recognized since, for flexibility, it was not coated with tar and therefore of a lighter color than the standing rigging which was tarred for protection from weather and therefore darker or even black in color. On modern vessels, running rigging is likely to be made from synthetic fibers, while the standing rigging is most often fashioned from stainless steel "wire rope".

1879 John A. Roebling's Sons Co. ad for wire rope Roebling devised "an equilibrium strength approach, in which equilibrium is always satisfied but compatibility of deformations is not enforced." This was essentially an approximation method similar to the force method: First, Roebling computed the dead and live loads, then divided the load between the cables and the stays. Roebling added a large safety factor to the divided loads and then solved for the forces. This approach gave a sufficiently accurate analysis of the structure given the assumption that the structure was sufficiently ductile to handle the resulting deformation (Buonopane, 2006).

Hammond was from Dundee, Scotland and had about nine years diving experience, three of which were in oilfield work. At 492 feet, supervisor Pettit stopped the bell, and for the next 90 minutes the two divers inspected the guide base from the portholes. Pettit had been told by the oil company representative that he would not find any remnant wires sticking out of the posts of the guide base, but Hoffman and Hammond reported that three of the guideposts had wire rope sticking out of, and draping over, their tops. These wires had to be cleared before the BOP could be sent down.

Richards was born and grew up in Newcastle, son of Ray and Val Richards, both keen beachgoers. They worked at the Wire Rope Works, Ray Richards as an accountant, but he wanted more than that career could offer and started a business selling second-hand cars, at a time when new cars were too expensive for most people. Together they set up a showroom at the end of Hunter St and lived in an apartment above it. In the late 1950s Ray saw the new balsa and fibreglass mailbu surfboards, which Greg Noll and other visiting Californians had brought with them in 1956.

Andrew Smith Hallidie was born Andrew Smith, later adopting the name Hallidie in honor of his uncle, Sir Andrew Hallidie. His birthplace is variously quoted as London in the United Kingdom. His mother, Julia Johnstone Smith, was from Lockerbie, Dumfriesshire and his father, Andrew Smith (a prolific inventor in his own right, responsible for inventing the first box door spring, a floor cramp and had an early patent for wire rope) was born in Fleming, Dumfrieshire, Scotland, in 1798.www.sfmuseum.org Andrew Smith Hallidie At age 13 the younger Smith was initially apprenticed to a machine shop and drawing office operated by his older brother Archibald.

Throughout his career Dunn demonstrated a profound concern for mine safety and was particularly interested in improvements to mine ventilation and flood prevention. He was a prolific author producing books, pamphlets, and practical papers on the coal trade and mining engineering, many covering safety topics. In particular he emphasised the need for adequate underground air-flow rate to neutralize gases, and promoted developments such as the use of barometers to monitor changes; cast- iron equipment; improved boiler safety valves and wire rope. He championed the better management of safety lamps and encouraged the work of those like William Reid Clanny who made improvements to lamps.

In 1916, the organisation renamed itself the "National Union of General Workers", merging with the Amalgamated Union of Machine and General Labourers. Further mergers followed, principally with the British Labour Amalgamation, the Amalgamated Society of Gas, Municipal and General Workers, the Amalgamated Enginemen, Cranemen, Boilermen, Firemen and Wire Rope Workers Union and the National Federation of Women Workers. This last merger was particularly significant, as it brought 30,000 women into the union. Unlike many other unions, the NUGW only had a small staff at its headquarters, consisting of Clynes, Jones, Thorne and Will Sherwood, later joined by Margaret Bondfield from the National Union of Women Workers.

A John Fowler & Co. Ploughing Engine - the winding drum is mounted below the boiler (the 'drum' on the side is actually a hose for refilling the water tank). A lockable tool box may be seen on the front axle; the 'spud tray' would be mounted in the same way, behind the axle. A distinct form of traction engine, characterised by the provision of a large diameter winding drum driven by separate gearing from the steam engine. Onto the drum a long length of wire rope was wound, which was used to haul an implement, such as a plough, across a field, while the engine remained on the headland.

At one point all further construction ceased while a stopper was placed on the special cable because most of the connection to the wire rope had broken and the string was being held by a few strands of wire on the double drum winch on YFNB-12. The YFNB-12 was held in place with four Murray and Tregurtha Diesel outboard engines placed on the corners and capable of 360 degree rotation, developing tremendous thrust in any direction.The information is from an anonymous personal recollection moved to Talk:Project Artemis in 2009. A reliable source describing the laying of the Artemis cables has not been found in extensive searches.

Window cleaning incident in 2013 The facade of the Hearst Tower is jagged. Plans for a rig, designed by Tractel- Swingstage, to hold window cleaners, took 3 years and $3 million because of the concave window structures at the building's corners, referred to as "bird's mouths". The resulting design incorporates "a rectangular steel box the size of a Smart car, supporting a 40-foot mast and hydraulic boom arm attached by six strands of wire rope to a telescopic cleaning basket, [and housing] a computer that monitors 67 electromechanical safety sensors and switches". The device was installed in April 2005 on of elevated steel track looping the roof of the tower.

USNS Josiah Willard Gibbs in the 1960s. After eleven years of inactivity, San Carlos was taken out of reserve on 11 July 1958 and assigned to the U.S. Navys Military Sea Transportation Service for conversion to an oceanographic research ship by Mobile Ship Repair Company of Mobile, Alabama. Alterations to her original design included the installation of six laboratories, a machine shop, a darkroom, a superstructure deck locker for experimental stowage or work, and a deep-sea winch capable of handling up to of wire rope and of equipment. In her modified form, she required a crew of 48 and could accommodate a scientific staff of 24.

The strengthened wire also made possible the construction of aeroplanes and automobiles. The company today also makes springs. Latch and Batchelor: Founded by Arthur Latch, Telford Clarence Batchelor and Henry Herbert Horsfall to develop Batchelor's patent of Locked Coil Wire Rope and Flattened Strand, it was formed in 1884 on part of the Hay Mills site owned at that time by Webster and Horsfall Ltd. Due to its smooth outer layer Locked Coil became increasing popular with its use in aerial ropeways and its unexpected yet excellent non-spinning properties and high breaking-strength-to-weight ratio were recognised by the mining industry and adopted worldwide.

By the 1880s Andrew S. Hallidie, a wire rope manufacturer, had built his country home of Eagle Home Farm in what is now Portola Valley. He built a 7,341 foot long aerial tramway from his house to the top of Skyline in 1894 though it was removed after his death in 1900. In 1886 the name Portola-Crespi Valley was bestowed on the area from the then community of Crystal Springs (now under Crystal Springs Reservoir to the then community of Searsville (in the area of the present day Jasper Ridge Biological Preserve); Crespi is for Juan Crespí, a Franciscan friar with the Portola expedition. The town was incorporated in 1964.

The 1868 Franz Joseph Bridge The Ordish–Lefeuvre system, or Ordish–Lefeuvre principle, is an early form of cable-stayed bridge design, patented by Rowland Mason Ordish and William Henry Le Feuvre in 1858. The Ordish–Lefeuvre system differs from conventional suspension bridges in that, while as with a conventional suspension bridge a parabolic cable supports the centre of the bridge, inclined stays support the remainder of the bridge's load. Each stay consists of a flat wrought iron bar attached to the bridge deck, and a wire rope connects the wrought iron bar to one of four octagonal support columns. Only two major bridges were built using the Ordish–Lefeuvre principle.

Meanwhile, LaDonna has met with the governor of Tennessee, where she, with use of a rather direct and blunt threat of blackmail, manages to get a formal guarantee that they will be given a proper extradition hearing. A showdown brews at the Tennessee state line, where a huge crowd of supporters for the tank and its crew has gathered. Using a vintage antitank weapon, Buelton manages to immobilize the tank within a mud flat, forcing Billy to consider surrender. However, a motorcycle gang intervenes and attaches a wire rope to the tank, and the assembled crowd works to pull the Sherman out of the trap.

In simplest form, a land-based lifeline consists of a horizontal wire rope cable attached to two or more anchor points on a roof-top, crane runway, bridge or outdoor construction site, or any other elevated work area that poses a fall risk. OSHA defines an anchorage in a fall protection system "a secure point of attachment for lifelines, lanyards, or deceleration devices".OSHA: Fall Protection in Construction Construction site lifeline systems include dedicated attachment brackets, safety lanyards and harnesses.Construction Lifelines Construction lifeline systems may be subdivided into those used to arrest workers in the event of a fall (active systems), or restrain workers from reaching a fall hazard (restraint systems).

American inventor Peter Cooper is one early claimant, constructing an aerial tramway using wire rope in Baltimore 1832, to move landfill materials. Though there is only partial evidence for the claimed 1832 tramway, Cooper was involved in many of such tramways built in the 1850s, and in 1853 he built a two-mile-long tramway to transport iron ore to his blast furnaces at Ringwood, New Jersey. World War I motivated extensive use of military tramways for warfare between Italy and Austria. During the industrial revolution, new forms of cable-hauled transportation systems were created including the use of steel cable to allow for greater load support and larger systems.

The anchor box had wheels allowing the mine assembly to be moved along a system of rails aboard the minelayer. The mine was connected to its anchor box by a wire rope mooring cable stored on a reel. The depth of the mine below the water surface was controlled by allowing the steel mooring cable to unwind from its reel as the mine was dropped from the minelayer until a sensor suspended beneath the anchor reached the bottom. The sensor locked the cable reel so the falling anchor would pull the buoyant mine below the surface; and the float extended the antenna above the mine.

Modern wire rope was invented to service the iron mines in the 1830s by the German mining engineer Wilhelm Albert in the years between 1831 and 1834 for use in mining in the Harz Mountains in Clausthal. It was quickly accepted because it proved superior to ropes made of hemp or to metal chains, such as had been used before and soon found its way into diverse applications, including most notably, suspension bridges. The Innerste Valley Railway was inaugurated in 1877 and extended to Altenau in 1914. The large station building and 70 other buildings in the town were destroyed in an air raid on 7 October 1944.

There were to be two inclined planes; one at Colton (332 yards with a gradient of 1 in 24) and one at Fordell House, known as the Vantage incline. Vantage was 1148 yards long with a gradient of 1 in 23.75. At Hillend an extra horse was stationed to assist waggons up the incline. The inclined planes used a large wheel round which the rope (later a wire rope) passed and there was a brake on the drum enabling a man to control the speed of the movement; it was worked on the balanced system: four loaded waggons descended and hauled four empties up.

Electric fencing made of modern synthetic materials with fine wire interwoven throughout make a visible and inexpensive fence. Use of plastic posts allows a temporary fence to be set up and moved easily as needed. An electric fence such as this is good for dividing up a grazing area, but should not be used as a boundary fence or in areas where animals will put a lot of pressure on the fence Electric fence comes in many styles of wire, rope and webbing, and is particularly useful for internal division of pastures. It carries only a mild charge that causes a noticeable shock, but no permanent injury to animals or people.

Close-up of strings for a piano shows "overspun" helical wire wrapping added to main carrier wires Wire has many uses. It forms the raw material of many important manufacturers, such as the wire netting industry, engineered springs, wire- cloth making and wire rope spinning, in which it occupies a place analogous to a textile fiber. Wire-cloth of all degrees of strength and fineness of mesh is used for sifting and screening machinery, for draining paper pulp, for window screens, and for many other purposes. Vast quantities of aluminium, copper, nickel and steel wire are employed for telephone and data cables, and as conductors in electric power transmission, and heating.

The railway afterwards used the cable in a wet railway tunnel.Haigh, pp. 26–27 This trial was followed in 1849 by an order for of cable from the Submarine Telegraph Company to lay a cable from Dover to Calais. This cable, laid in 1850, soon failed, largely because the Submarine Telegraph Company failed to have it armoured. Undeterred, the company placed a new order in 1850, but this time the cable was to be sent to a wire rope manufacturer for armouring before laying. This order was four timesScott as large as the 1849 order since the new cable was to have four gutta-percha insulated cores.

The process of protecting wire rope standing rigging is described in the book Star of India, The Log of an Iron Ship - Page 116, Footnote 3 > To protect wire rigging from moisture and resultant rusting, it first is > "wormed" by laying small line in the spiral grooves between the strands, to > make a smoother surface. It then is "parceled" by wrapping in the same > direction with long strips of cotton duck (burlap if you're poor) and > finally it is "served" by wrapping it in the opposite direction with > hambroline, a three-stranded tarred hemp cord, a little smaller in diameter > than a lead pencil. Finally it is well treated with Stockholm tar.

Typical K values are 1.04 for roller bearing sheaves and 1.09 for plain bearing sheaves (with wire rope). The increased force produced by a tackle is offset by both the increased length of rope needed and the friction in the system. In order to raise a block and tackle with a mechanical advantage of 6 a distance of 1 metre, it is necessary to pull 6 metres of rope through the blocks. Frictional losses also mean there is a practical point at which the benefit of adding a further sheave is offset by the incremental increase in friction which would require additional force to be applied in order to lift the load.

The original tool of this type was developed by Abraham Maasdam of Deep Creek, Colorado, about 1919, and later commercialized by his son, Felber Maasdam, about 1946. It has been copied by many manufacturers in recent decades. A similar heavy-duty unit with a combination chain and cable became available in 1935 that was used by railroads, but lacked the success of the cable-only type units."New Jack Enables One Man To Pull Heavy Loads" Popular Science, May 1935, article & photo bottom of page 39 A similar tool to a come-along is a cable puller, which does not have a drum and ratchet but directly grips the cable, allowing unlimited lengths of wire rope to be used.

The spruce boom is 10' in length, grooved for the bolt rope foot. Some early out haul designs had a metal bail attached aft end through which a wire outhaul ran, swagged to a wire and run to a cleat on the bottom of the boom near the main sheet block through a groove in the boom's and the tag runs to a cleat. The goose neck is pin-style with a 90-degree tang that has a hole in it and sits over a screw below the stainless pin receiver on the mast, preventing the boom from swinging independent of the mast. Original halyard is wire/rope, with a ball stop on the wire but now vary.

Supplies were taken up the rock face by an aerial hoist: a wire rope strung between the island and an adjacent islet was rigged with a traveller, which enabled goods to be winched up from delivery boats below. Within the walls of the lighthouse the keepers tended a small vegetable garden, for which the soil was transported to the island. The light has a focal plane of 180 feet, and originally had an enormous biform hyperradial optic high and weighing more than 8 tons. It was built by Chance Brothers & Co of Birmingham and, said at the time, to be ″ .... in relation both to size and character .... the most remarkable works of their kind hitherto achieved.

The objective of a defensive minefield is to restrict movement of enemy ships into areas used by friendly shipping. The assumed presence of a minefield may have a morale effect of assumed risk in addition to actually damaging ships attempting to cross the field. In July 1939, before World War II had begun, the possibility of a Northern Barrage between the Orkney Islands and Norway (similar to the North Sea Mine Barrage of World War I) had been considered, however other alternatives were investigated after the occupation of Norway by the Germans in April 1940. Conventional mines of the era employed a contact-fuzed explosive charge within a buoyant shell suspended over an anchor attached by a wire rope.

The vessel can employ one of two winches for towing operations. The main towing winch for large, long distance tows is a single drum, closed-loop SMATCO electro-hydraulic drive winch, with a mechanically, pneumatically, or hydraulically actuated band brake and an air-actuated dog brake which are capable of holding 500,000 lbf of tension. The winch has of 2¼ inch IWRC 6×37 wire rope with a poured end fitting and a breaking strain of 424,000 lbf (1.89 MN). The cable weighs approximately 8.5 lb per foot (12.6 kg/m), making the weight of the wire approximately 21,500 lb (10.75 short tons) excluding the weight of any chain bridle used on the vessel being towed.

Original layout of Stockwell station and depot Just north of the station there is a branch tunnel which used to lead to a nearby generating station (closed 1915), depot and workshop located at the junction of Stockwell and Clapham Roads. The tunnel was very steep with an incline of 1:3.5, so rolling stock was originally pulled up to the surface using a wire rope and a winch. This system was replaced in 1907 by a hydraulic lift, which could carry one locomotive or one carriage. During the 1920s, the line was closed for reconstruction and the depot was used as a working site for transporting spoil, equipment and works traffic in and out of the tunnels.

The wire is then bent around so that the end of the unwrapped length forms an eye and the unwrapped strands are then plaited back into the wire rope, forming the loop, or an eye, called an eye splice. A Flemish eye, or Dutch Splice, involves un wrapping three strands (the strands need to be next to each other, not alternates) of the wire and keeping them off to one side. The remaining strands are bent around, until the end of the wire meets the "V" where the unwrapping finished, to form the eye. The strands kept to one side are now re-wrapped by wrapping from the end of the wire back to the V of the eye.

Although this timber truss bridge was constructed to be a "permanent" structure, it was soon discovered that the bridge's condition was deteriorating. In 1893 two large girders and wire rope were placed under the structure for additional strength. At the same time, planning began for the replacement of the bridge with a new suspension bridge which was to become far-famed as "the greatest feat of engineering in the valley and the second greatest in the colony of New South Wales".Bayley (1953) in Austral Archaeology Pty Ltd (2001, 5) Farm amalgamations in the twentieth century have reduced the population greatly, and hobby farmers and retirees are increasingly attracted to the valley.

Traditionally, sisal has been the leading material for agricultural twine (binder twine and baler twine) because of its strength, durability, ability to stretch, affinity for certain dyestuffs, and resistance to deterioration in saltwater. The importance of this traditional use is diminishing with competition from polypropylene and the development of other haymaking techniques, while new higher-valued sisal products have been developed. Apart from ropes, twines, and general cordage, sisal is used in low-cost and specialty paper, dartboards, buffing cloth, filters, geotextiles, mattresses, carpets, handicrafts, wire rope cores, and Macramé. Sisal has been utilized as an environmentally friendly strengthening agent to replace asbestos and fibreglass in composite materials in various uses including the automobile industry.

Novelty was launched in 1863 by P.N. Russell and Company, the Sydney foundry owned and operated by the Australian engineer Peter Nicol Russell. Its length was 82.5 ft, beam 15.5 ft, depth 5.3 ft, weight 376 tons. After being delivered to New Zealand, Novelty was outfitted and furnished in Auckland, where there was a launching ceremony on 1 February 1863. The New Zealander newspaper described Novelty in its report of the launching ceremony: > From truck to deck, all is clean, well set up, and ship shape' her masts > well placed and stayed; and her rigging sweated down until her shrouds stand > out like so many bars of iron;-in fact, the greater proportion of her stays > are so, being of iron wire rope.

The grab mechanism may be four rope, double rope, single rope ring discharge, single rope self-dumping, double chain, single chain self-dumping, single chain ring discharge, hydraulic or electro- hydraulic. Rope grabs have rope pulleys in both the upper and lower girders and close by drawing the closing rope(s) to shorten the gap between the two girders. The minimum diameter of the pulley is restricted by the ratio of the pulley diameter to the rope diameter, the strands of the wire rope being subjected to fatigue bending stresses if the pulley is too small, giving premature failure. The physical size of the pulleys then determines the size of the girders, then determining a break point between a four rope and a two rope design.

The final round of the tournament was a Barbed Wire Rope, Exploding Barbed Wire Boards and Exploding Ring Time Bomb Deathmatch between Terry Funk and Cactus Jack. Tiger Jeet Singh interfered in the match on Jack's behalf by hitting Funk with a sabre and then the two whipped him into the barbed wire which allowed Jack to gain momentum over Funk. Near the end of the match, Jack hit a diving elbow drop to Funk from the top of a ladder to gain a near-fall and then climbed the ladder to hit a second diving elbow drop but Funk knocked him out and Jack fell into the barbed wire ropes. Funk then collapsed himself into the barbed wire ropes.

When the YN&BR; diverted services onto the direct line to Pelaw, they began to use a new station in Washington, 600yd to north east of the original and only the market day services to Durham Turnpike continued to use the first station until they were withdrawn in December 1853. The second station was situated on Station Road, south of the railway bridge and level crossing on Usworth Station Road and Washington Road respectively and was closer to Washington Village than the first station had been. Adjacent to the station were brickworks a wire rope works and a large chemicals plant. North of the footbridge were two buildings: one was the rear of a goods shed and the other was lower with a hipped roof.

A rosette sampler is made of an assembly of 12 to 36 sampling bottles.Woods Hole Oceanographic Institution, "Rosette Sampler" Each bottle is a volume that range from a minimum value of 1.2 L to a maximum value of 30 L. All of them constitutes the rosette sampler and are clustered around a cylinder situated in the center of the assembly, where there is a sensing system called Sea-Bird or CTD, that stands for "Conductivity, Temperature and Depth", although other variables can be measured by modern CTDs (e.g. water turbidity, dissolved oxygen concentration, chlorophyll concentration and pH).Civil & Environmental Engineering Department at Michigan Tech, "CTD and the Rosette samples on Lake Superior" The apparatus is attached to a wire rope.

A wire rope terminated with a thimble and a ferrule Picco pipe with nickel silver ferrule Non-circular ferrules holding bristles of a brush to its handle A ferrule (a corruption of Latin ' "small bracelet", under the influence of ' "iron") is any of a number of types of objects, generally used for fastening, joining, sealing, or reinforcement. They are often narrow circular rings made from metal, or less commonly, plastic. Ferrules are also often referred to as eyelets or grommets within the manufacturing industry. Most ferrules consist of a circular clamp used to hold together and attach fibers, wires, or posts, generally by crimping, swaging, or otherwise deforming the ferrule to permanently tighten it onto the parts that it holds.

On August 20, 1995, IWA organized a King of the Death Match tournament at their Kawasaki Dream event, which featured some of the bloodiest, most violent and most brutal matches of Foley's career. Each level of the tournament featured a new and deadly gimmick: Cactus Jack's first-round during the day was a barbed-wire baseball bat, thumbtack deathmatch, in which he defeated Terry Gordy; the second round was a barbed-wire board, bed of nails match where Cactus Jack defeated Shoji Nakamaki. The final, at night against Terry Funk, was a barbed-wire rope, barbed-wire and C4 board, time-bomb deathmatch, which Cactus Jack won with help from Tiger Jeet Singh. After the match, both men were covered in blood, ravaged by flesh cuts from the wire and burned by the C4 explosions.

Edwin Clark's best known achievement in the UK, the Anderton Boat Lift Lift at Strépy-Bracquegnies (Belgium), one of a series of four World Heritage Clark lifts Clark was an experienced Hydraulic Engineer with the firm of Clark, Stansfield & Clark, consulting engineers of Westminster, when he was called upon in 1870 by Edward Leader Williams to design a boat lift to raise boats 50 feet from the River Weaver to the Trent and Mersey Canal. Clark designed the original hydraulic structure opened in 1875, which was later replaced by a wire rope and pulley system from 1908 to 1983 before being returned to hydraulic operation in 2002. He went on to design other boat lifts in other European countries. In 1879, he presented a project to the Belgian government that included four of his lifts.

A company operating notice of 14 December 1843 calls it "Victoria station at Hunt's Bank near the Exchange." and at the time of its completion was the largest station in the country. Even so, a single platform was considered sufficient for all the traffic, the west end for the Liverpool trains and the east for the Leeds trains: it was 852 ft long.Bairstow, page 26Marshall, pages 55 to 57 The trains were hauled up to Miles Platting by a wire rope; descending trains were controlled by brake wagons in front. In the Railway Chronicle 3 May 1845 (p 500) Hawkshaw is reported as saying that the use of the stationary engine had been largely discontinued, the ordinary engines taking up passenger and goods trains weighing over eighty tons.

Rails were laid on the slip, and single wagons were worked down to the steamers using a wire rope; passengers, however, walked to a platform at Burnham station nearby. In both cases the arrangement was awkward and inconvenient, and the anticipated traffic growth never materialised, and the Burnham Pier, which had cost £20,000, was a financial failure. At the eastern end, a branch to the important city of Wells was opened on 15 March 1859. This had originally been planned to be part of a main line extension towards Frome, where the Wilts, Somerset and Weymouth Railway could be joined, giving the yearned-for access to the South Coast towns, but by now the Somerset Central thought that joining up with the Dorset Central Railway would be a more cost-effective option.

A train (or an individual car) can be pushed halfway across the gauge- changer, uncoupled, and then (once far enough across) coupled to the new locomotive and pulled the rest of the way. A long length of wire-rope with hooks on the end means that the process can be asynchronous, with the rope used to bridge across the length of the gauge changer (to temporarily couple the arriving cars and receiving locomotive, although without braking control from the locomotive to the train vehicles). On long-distance trains in Spain and night trains crossing from Spain into France, the arriving locomotive stops just short of the gauge changer, uncouples and moves into a short siding out of the way. Gravity then moves the train through the gauge changer at a controlled low speed.

To get the camera out over the centre of larger shafts, I.A.Recordings use either a scaffold pole with a pulley on the end, or for shafts that have run-in so the crater on the surface is several metres wide, they have developed a "Tyrolean traverse" or "Blondin" arrangement. A large diameter pulley (a Sinclair C5 wheel) is mounted on a trolley which is winched along a wire rope slung across the shaft and kept in tension. When the pulley is centred, the traverse rope is locked-off and the camera lowering rope can be released. The 50 W lamp & reflector is a convenient size and is available in a variety of beam-widths, but the idea of the dichroic reflector preventing heat being reflected forward is actually a disadvantage for the MineCam.

The Catalogue, The National Archives wide sections were preassembled and then carried to the sea to be placed in position at the half tide mark as an obstacle to boats. However, trials found that a 250-ton barge at or an 80-ton trawler at would pass through the obstacle as if it were not there and a trawler easily pulled out one bay with an attached wire rope. Tests in October 1940, confirmed that tanks could only break through with difficulty, as a result Z.1 was adopted as an anti-tank barrier for beaches thought suitable for landing tanks. As an anti-tank barrier it was placed at or just above the high water point where it would be difficult for tanks to get enough momentum to break through the barrier.

The banking engines were sent to the Monklands area in 1848, and wire rope haulage with the stationary engine was used instead. The endless rope for the incline was driven by two beam engines at Cowlairs, of the high pressure type, made by Kerr, Neilson and Company of Glasgow. They had 28 inch cylinders, and 72 inch stroke. The crankshaft had a spur wheel of 12 feet diameter, which drove the cable drum through gearing. The main cable drum was 18 feet in diameter, mounted in a pit under the track. The beam engines were supplied with steam at 50 psi by 8 boilers, each 30 feet long and 5 feet diameter. The boilers were replaced in 1862 – 1863 by seven Cornish boilers. The cable haulage continued in operation until 31 January 1908, when banking engines took over.

A U.S. postage stamp issued to commemorate the Atlantic cable centenary The cable consisted of seven copper wires, each weighing 26 kg/km (107 pounds per nautical mile), covered with three coats of gutta-percha (as suggested by Jonathan Nash Hearder), weighing 64 kg/km (261 pounds per nautical mile), and wound with tarred hemp, over which a sheath of 18 strands, each of seven iron wires, was laid in a close helix. It weighed nearly 550 kg/km (1.1 tons per nautical mile), was relatively flexible and was able to withstand a pull of several tens of kilonewtons (several tons). The cable from the Gutta Percha Company was armoured separately by wire rope manufacturers, as was the usual practice at the time. In the rush to proceed, only four months were allowed for completion of the cable.

The stationary engines at Cowlairs were scrapped the following year. An accident took place in 1869 and the Inspecting Officer's report gives a flavour of the operations on the incline: > Trains are worked up the incline between Queen's Street station and Cowlairs > by attaching them to an endless wire rope, which is worked by a stationary > engine at the top of the incline, and trains are piloted down the incline > from Cowlairs to Queen's Street station, by attaching heavy breaks with a > breaksman in each break in front of the trains. Sometimes the engines remain > attached to the tail of the trains in descending the incline, and sometimes > the trains proceed without an engine. This depends on whether the engine is > required at Queen's Street or not, but in every case the breaksmen, who > travel on the incline breaks in front of the train, are placed in charge of > the train.

These major employers were accompanied by numerous smaller concerns, including dyeworks, bleachworks, wire ropeworks, brickworks, screw manufacturers, makers of surveying equipment, and a tobacco factory.Downham. A small number of closures of major industrial employers took place in the first half of the 20th century, due to the ebb and flow of trade. Andrew's Gas Engine Works was taken over in 1905 by Richard Hornsby & Sons of Grantham,Astle the business was transferred to Grantham and the Reddish works closed some time during the great depression following WWI. Cronin indicates that the works were still in operation in 1930.Cronin, p82. The Atlas wire rope works closed in 1927.Ashmore, pp 45, 86. Reddish took its share of the decline in Lancashire cotton production and finishing. Broadstone Mills ceased production in 1959;Holden p168, Ashmore p84, Arrowsmith p258.

F-14 Tomcat preparing to connect to a catapult on An aircraft catapult is a external device used to allow aircraft to takeoff from a very limited amount of space, such as the deck of a vessel, but also installed land-based runways in rare cases. It is now most commonly used on aircraft carriers, as a form of assisted take off. In the form used on aircraft carriers the catapult consists of a track, or slot, built into the flight deck, below which is a large piston or shuttle that is attached through the track to the nose gear of the aircraft, or in some cases a wire rope, called a catapult bridle, is attached to the aircraft and the catapult shuttle. Other forms have been used historically, such as mounting a launching cart holding a seaplane on a long girder-built structure mounted on the deck of a warship or merchant vessel, but most catapults share a similar sliding track concept.

He first worked on projects to improve river navigation and build canals. For three years, he conducted surveys for railway lines across the Allegheny Mountains, from Harrisburg to Pittsburgh, for the state of Pennsylvania. In 1840 he wrote to suspension bridge designer Charles Ellet, Jr., offering to help with the design of a bridge near Philadelphia:Steinman, David B. & Watson, Sara Ruth, Bridges and their Builders, 1941 > The study of suspension bridges formed for the last few years of my > residence in Europe my favourite occupation ...

The area around Mauch Chunk was known as the "Switzerland of America", the long wide slack water pool above the Lehigh's upper dam being surrounded by Mauch Chunk Ridge, Bear Mountain, Pisgah Ridge, Mount Pisgah, Nesquehoning Ridge, Broad Mountain and their various prominences and summits. Another railroad first, the first railway to operate steam locomotives as traction engines and prime movers in the United States was the Beaver Meadows Railroad, which connected from mines west of Beaver Meadows and Weatherly on the opposite side of Broad Mountain along a water path through the Lehigh Gorge at Penn Haven Junction (once supporting five railroads) to the Lehigh Canal opposite Lehighton. In the 1830s, the first blast furnaces in Northampton County were built by the LC&N; in an attempt to make anthracite iron, the foundation of the early industrial revolution in America. The LC&N; also built the first wire rope factory in the U.S. in Mauch Chunk.

Ever looking for better ways in the 1820s he and Hazard experimented with blast furnace production of smelted pig iron using charges of anthracite in Mauch Chunk, and succeeded in part, perhaps as much as any in America, for their processes could not always reliably repeat, so were not commercially viable in the long run. This primed them to import skills and necessary equipment when news of successful use of anthracite pig iron processes arrived from Wales in 1838; subsequently he invested heavily and had, as the operating manager, had the Lehigh Coal & Navigation Company invest in the Lehigh Crane Iron Company backing the importing of professional talent from Wales to establish the first sustainably-successful blast furnaces of the region in Catasauqua, and established the first wire rope (steel cable) factory in the United States in Mauch Chunk which enabled the Ashley Planes and up cable railway conversion & expansion of the Summit Hill & Mauch Chunk Railroad.

The U.S. Navy again requisitioned Brown Bear when she arrived at Juneau in 1951, but by the summer of 1952 the University of Washington's Department of Oceanography had acquired her. The university employed her in research projects in Alaska, off the coasts of Washington and Oregon, and in parts of the Columbia River, and she often operated in cooperation with vessels from other agencies. In 1956 and 1957, Brown Bear worked with the FWS vessels US FWS Skipjack and US FWS Teal to support a study of the estuarine circulation of water in Silver Bay, a deep-water fjord in Alaska near Sitka. Equipped with 31,000 feet (9,449 meters) of wire rope and sampling gear to allow her to make soundings in waters up to 20,000 feet (6,096 meters) deep, she made an oceanographic expedition in the summer of 1957 as part of an international project to study the Pacific Ocean, including the Aleutian Trench.

This model is still in existence in the London Science Museum. The track for the vehicle was laid in the grounds of Brennan's house in Gillingham, Kent. It consisted of ordinary gas piping laid on wooden sleepers, with a fifty-foot wire rope bridge, sharp corners and slopes up to one in five. Brennan demonstrated his model in a lecture to the Royal Society in 1907 when it was shown running back and forth "on a taught and slender wire" "under the perfect control of the inventor".Revolution in Travel, Birmingham Daily Gazette, 9 May 1907, p8 Brennan's reduced scale railway largely vindicated the War Department's initial enthusiasm. However, the election in 1906 of a Liberal government, with policies of financial retrenchment, effectively stopped the funding from the Army. However, the India Office voted an advance of £6000 in 1907 to develop the monorail for the North West Frontier region, and a further £5000 was advanced by the Durbar of Kashmir in 1908.
