The electric plant provided for ice machines, refrigeration and machinery such as windlasses as well as lighting.

The Saipem 7000 is also equipped with two anchor windlasses equipped with 550m of 130mm chain and 35 tonne anchor.

It tends to be the case that smaller boats use capstans, and larger boats have windlasses, although this is by no means a hard and fast rule.

Windlasses were going in all directions, tents erected in every available spot. The riches dug up were enormous. At this time, the main street was being formed at the Crescent. By March 1859 there was an estimate of 15,000 people at the rush.

In general, windlasses and their power system should be capable of lifting the anchor and all its rode (chain and rope) if deployed so that it hangs suspended in deep water. This task should be within the windlass' rated working pull, not its maximum pull.

Typical areas of application were harbours, mines, and, in particular, building sites where the treadwheel crane played a pivotal role in the construction of the lofty Gothic cathedrals. Nevertheless, both archival and pictorial sources of the time suggest that newly introduced machines like treadwheels or wheelbarrows did not completely replace more labor-intensive methods like ladders, hods and handbarrows. Rather, old and new machinery continued to coexist on medieval construction sites and harbours. Apart from treadwheels, medieval depictions also show cranes to be powered manually by windlasses with radiating spokes, cranks and by the 15th century also by windlasses shaped like a ship's wheel.

To secure and add strength to the hull, cables (hypozōmata) were employed, fitted in the keel and stretched by means of windlasses. Hence the triremes were often called "girded" when in commission.Fields (2007), p. 9 The materials from which the trireme was constructed were an important aspect of its design.

The Luttrell Psalter, dating to around 1340, describes a grindstone which was rotated by two cranks, one at each end of its axle; the geared hand-mill, operated either with one or two cranks, appeared later in the 15th century; Medieval cranes were occasionally powered by cranks, although more often by windlasses.

Lockkeepers were on call 24 hours a day during the boating season. On the Chesapeake and Ohio Canal, the lock keepers were required to remove the windlasses from all lock paddles at night, to prevent unauthorized use. But they had to get up and man the lock if a boat came through at night. Lock keepers had to enforce company rules against independent and wily boat captains.

While most windlasses require power, many are manually driven in the same manner as most sailing boats' winches for sheets. In fact only modern boats have practical sources for power, and ships in the old days have always required manual power. Powered solutions include steam (antiquated), hydraulics, and electrics. Electrics are convenient and relatively cheap, but hydraulics prove more efficient and powerful on all but small boats.

Technically speaking, the term "windlass" refers only to horizontal winches. Vertical designs are correctly called capstans. Horizontal windlasses make use of an integral gearbox and motor assembly, all typically located above-deck, with a horizontal shaft through the unit and wheels for chain and/or rope on either side. Vertical capstans use a vertical shaft, with the motor and gearbox situated below the winch unit (usually below decks).
|
|
Horizontal windlasses offer several advantages. The unit tends to be more self-contained, protecting the machinery from the corrosive environment found on boats. The dual wheels also allow two anchors on double rollers to be serviced. Vertical capstans, for their part, allow the machinery to be placed below decks, thus lowering the center of gravity (important on boats), and also allow a flexible angle of pull (which means rope or chain can be run out to different fair leads).

The ships have the capability to supply fuel and other liquid cargo to vessels using replenishment rigs on port and starboard beams and through a Hudson reel-type stern rig. When providing support for amphibious operations, the ships are also able to deliver fuel to dracones positioned alongside. The equipment load includes cranes (for stores handling and abeam replenishment), steering and rudder gear, thyristor- controlled winch/windlasses and double drum mooring winches. Up to of liquids and of general solids can be carried.

Treadwheel crane Treadwheel crane (1220s) The earliest reference to a treadwheel in archival literature is in France about 1225, followed by an illuminated depiction in a manuscript of probably also French origin dating to 1240. Apart from tread-drums, windlasses and occasionally cranks were employed for powering cranes. Stationary harbour crane (1244) Stationary harbour cranes are considered a new development of the Middle Ages; its earliest use being documented for Utrecht in 1244. The typical harbour crane was a pivoting structure equipped with double treadwheels.

Bath Iron Works was incorporated in 1884 by General Thomas W. Hyde, a native of Bath who served in the American Civil War. After the war, he bought a shop that made windlasses and other iron hardware for the wooden ships built in Bath's many shipyards. He expanded the business by improving its practices, entering new markets, and acquiring other local businesses. By 1882, Hyde Windlass was eyeing the new and growing business of iron shipbuilding, and it incorporated as Bath Iron Works in 1884.

Two three room cottages made from jarrah with iron roofing, a corrugated iron woolshed, yards, sleeping quarters, kitchen and blacksmith shop had been built along with seven paddocks contained within of fencing. Stocked with 11,600 mixed sheep, 230 cattle and 180 horses watered by the river and seven windlasses it was acquired by G.P Paterson and A.R. Richardson, who had previously partly owned Yeeda Station. In 1915, the property passed 16,500 sheep over the boards during shearing producing 250 bales of wool. This followed an excellent season where the was recorded in six months.

Louis XV of France had a so-called 'flying chair' built for one of his mistresses at the Chateau de Versailles in 1743. Ancient and medieval elevators used drive systems based on hoists or windlasses. The invention of a system based on the screw drive was perhaps the most important step in elevator technology since ancient times, leading to the creation of modern passenger elevators. The first screw drive elevator was built by Ivan Kulibin and installed in the Winter Palace in 1793, although there may have been an earlier design by Leonardo da Vinci.

The next day, the emperor summoned Symphorosa's seven sons, and being equally unsuccessful in his attempts to make them sacrifice to the gods, he ordered them to be tied to seven stakes erected for the purpose round the Temple of Hercules. Their members were disjointed with windlasses. Then, each of them suffered a different kind of martyrdom. Crescens was pierced through the throat, Julian through the breast, Nemesius through the heart, Primitivus was wounded at the navel, Justinus was pierced through the back, Stracteus (Stacteus, Estacteus) was wounded at the side, and Eugenius was cleft in two parts from top to bottom.

These climbing shafts were usually within the miners' coe, the limestone-walled cabin in which they stored tools, a change of clothes and food. Where the mine was on a hillside the vein could often be reached via an adit or tunnel driven into the slope. Ore was brought to the surface up a winding shaft outside the coe. The miners' equipment included picks, hammers and wedges to split the rock, wiskets or baskets to contain it, corves or sledges to drag it to the shaft bottom, and windlasses or stows, to lift it to the surface.

In keeping with the general philosophy of working boats, all sails would therefore be traditionally treated with red oxide and other substances. Foot of the forestay and windlasses on SB Pudge and SB Centaur The problem of the inaccessibility of gear was met in the Thames barge by stepping the mast in a tabernacle and using a windlass on the foredeck to strike the whole lot, mast, sprit, sails and rigging. The crew could sail under a low bridge such as at Aylesford or Rochester the without losing steerage way. The windlass is below the tack of the foresail and the tackle at the foot of the forestay.

Some unlucky miners met their deaths in blasting accidents at this time. Such mishaps could not deter the miners from the wealth that was found from this field. This must have been one of the, if not the most, exciting births of any town in the country. Noise and confusion from large numbers of excited diggers, the clang of anvils, the rattle of windlasses and the explosions from blasting. The sights recorded by visiting correspondents—a cake of gold (200 ounces or 6 kg) in a gold broker’s window in the crescent and in another, 1,500 ounces (47 kg) of nuggets—seem like fairy tales.

According to the Bureau of Naval Personnel (BUPERS), the job of a Machinist's Mate is to "operate, maintain, and repair (organizational and intermediate level) ship propulsion machinery, auxiliary equipment, and outside machinery, such as: steering engine, hoisting machinery, food preparation equipment, refrigeration and air conditioning equipment, windlasses, elevators, and laundry equipment. Operate and maintain (organizational and Intermediate level) marine boilers, pumps, forced draft blowers, and heat exchangers; perform tests, transfers, and inventory of lubricating oils, fuels, and water. Maintain records and reports, and may perform duties in the generation and stowage of industrial gases." Enlistees are taught the fundamentals of this rating through on-the-job training or formal Navy schooling.

15th century paddle-wheel boat whose paddles are turned by single-throw crankshafts (Anonymous of the Hussite Wars) The crank became common in Europe by the early 15th century, often seen in the works of those such as the German military engineer Konrad Kyeser. Devices depicted in Kyeser's Bellifortis include cranked windlasses (instead of spoke- wheels) for spanning siege crossbows, cranked chain of buckets for water- lifting and cranks fitted to a wheel of bells. Kyeser also equipped the Archimedes screws for water-raising with a crank handle, an innovation which subsequently replaced the ancient practice of working the pipe by treading. The earliest evidence for the fitting of a well-hoist with cranks is found in a miniature of c.

It had five inclines on either side of the drainage divide running athwart the ridge line from Blair Gap through along the kinked saddle at the summit into Cresson, Pennsylvania. The endpoints connected to the Canal at Johnstown on the west through the relative flats to Hollidaysburg on the east. The Railroad utilized cleverly designed wheeled barges to ride a narrow-gauge rail track with steam-powered stationary engines lifting the vehicles. The roadbed of the railroad did not incline monotonically upwards, but rose in relatively long, saw-toothed stretches of slightly-sloped flat terrain suitable to animal powered towing, alternating with steep cable railway inclined planes using static steam engine powered windlasses, similar to mechanisms of modern ski lifts.

It was said in her time the style in which James Baines's hull was designed and built, both inside and outside, has not been surpassed or equalled, by any other ship Donald McKay has ever constructed. The stern and the bow including the cutwater were beautifully adorned with gilded carvings, the ship's hull was painted black with blue waterways and a blue underwater ship. Her mast-heads and yards were black and equipped with iron caps, the hoops on her masts were held in white as well as the deck houses and rails. On Mr James Baines order the ship was equipped and fitted with the best and most modern ship improvements (pumps, windlasses & winches, Crane's self-acting chain-stoppers (invented in 1852)).

It begin with the ancient Egyptians who developed a "sack press" made of cloth that was squeezed with the aid of a giant tourniquet.H. Johnson Vintage: The Story of Wine pg 14-31 Simon and Schuster 1989 The ancient Greeks and Romans developed large wooden wine presses that utilized large beams, capstans and windlasses to exert pressure on the pomace. That style of wine press would eventually evolve into the basket press used in the Middle Ages by wine estates of the nobility and Catholic Church.T. Pellechia Wine: The 8,000-Year-Old Story of the Wine Trade pg 28, 50-51 and 149 Running Press, London 2006 There are many church records that showed feudal land tenants were willing to pay a portion of their crop to use a landlord's wine press if it was available.

Tables were built of wood and whale vertebrae were used as chairs. On a point five miles from the station they also erected a large tank for storing blubber, provided with windlasses for hoisting the blubber into the tank – a house was built nearby with a kitchen and two rooms for fourteen men. In 1864 and for most of 1865, Lindholm was only able to send out boat crews, which were fitted out for a fortnight to search for whales in Tugur Bay as well as nearby bays and gulfs. They cruised for whales during the day and camped on the beach at night. Lindholm later purchased two schooners: the Caroline (1865-1870), which he had bought from the Russian-American Company – along with its houses and trying-out establishment on the point at Mamga – and the 160-ton Hannah Rice (1866-1875), formerly a tender to a whaleship for a number of years.

Nossov, p. 124 From the 15th century, gunpowder was also used, although the aim remained to burn the props.Nossov, p. 126 Defenders might sometimes dig counter-tunnels in order to reach the enemy's mines and launch an attack; frequently thermal weapons were used to drive the besiegers from the tunnels.Nossov, pp. 129–131 Rather than undermining a structure, some besiegers used borers to drill holes in the outer walls in an effort to destroy them; such methods were more effective than rams on brick walls (which tended to absorb the shocks from the ram).Nossov, p. 99 Borers differed in size and mechanism, but a typical machine was made from a log of wood, tipped with iron and supported and driven by windlasses or ropes. Once a series of holes had been bored along the length of a wall, the holes were typically filled with rods of dry wood, saturated with sulfur or pitch and then ignited. Bellows could be used to encourage a blaze.

By at least the 18th dynasty, the ancient Egyptians were employing a "sack press" made of cloth that was squeezed with the aid of a giant tourniquet. The use of a wine press in winemaking is mentioned frequently in the Bible but these presses were more elaboration of treading lagars where grapes that were tread by feet with the juice running off into special basins. The more modern idea of a piece of a winemaking equipment used to extract the juice from the skins probably emerged during the Greco-Roman periods where written accounts by Cato the Elder, Marcus Terentius Varro, Pliny the Elder and others described wooden wine presses that utilized large beams, capstans and windlasses to exert pressure on the pomace.H. Johnson Vintage: The Story of Wine pg 70, 124-125, 147, 202-214 Simon and Schuster 1989 The wines produced by these presses were usually darker, with more color extracted from the skins but could also be more harsh with bitter tannins also extracted.

It was fitted with a novel hydraulic winch as the normal windlasses could not be used at speeds of much more than , while the Monitor was required to tow targets at double this speed. The original requirement for a target towing aircraft for the RAF was abandoned, and the orders for Monitors was taken over by the Fleet Air Arm, who required an aircraft capable of simulating dive-bombing attacks on warships. To meet this requirement the aircraft, fitted with hydraulically actuated dive brakes, nose cameras for marking Fleet gunnery, a dorsal midship cupola and radar equipment was used to accurately determine height was known as the Monitor TT Mk II. The Monitor's winch was fitted with of towing cable, and was capable of towing flag and sleeve targets as well as -span special winged targets. Spare targets were stowed on board and could be changed in flight, while winged targets were towed off the ground on a line.
