Its caterpillar tracks were not reliable enough to operate at such depth, so the company imagined two Archimedes screws to drag its vehicle through the mud.

Overlord rides the Bullwhip Cannon, an eight-wheel all-terrain vehicle equipped with a large laser cannon. The other Black Widows ride Sledge Hammers, a one-man minitank that has triangular caterpillar tracks and has whirling mace arms on either side. They also have a special delta-winged aircraft called the Intruder.

A Humvee with Fisher plow, serving with the United States Army 27th Engineer Battalion in Kosovo Modern winter service vehicles will usually also have a satellite navigation system connected to a weather forecast feed, allowing the driver to choose the best areas to treat and to avoid areas in which rain is likely, which can wash away the grit used—the most advanced can even adapt to changing conditions, ensuring optimal gritter and plow settings.Institution of Civil Engineers, pp. 53–54 Most run on wheels, often with snow chains or studded tires, but some are mounted on caterpillar tracks, with the tracks themselves adapted to throw the snow towards the side of the road. Off-road winter service vehicles mounted on caterpillar tracks are known as snowcats.

Lombard is credited with developing an early version of caterpillar tracks, a vehicular propulsion mechanism that eventually saw broad application in a variety of application, most notably in military vehicles and earthmoving equipment. The Lombard Steam Log Hauler was Lombard's effort to capitalize on this invention. He also patented a turbine water wheel control mechanism.

It differed from modern tanks in that it did not use caterpillar tracks--rather, it used a tricycle design. The two front spoked wheels were nearly in diameter; the rear-mounted third wheel was only high. The upper cannon turret reached a height of nearly . The hull was wide with two more cannon in sponsons.

Form follows function. # Robots have electrical components which power and control the machinery. For example, the robot with caterpillar tracks would need some kind of power to move the tracker treads. That power comes in the form of electricity, which will have to travel through a wire and originate from a battery, a basic electrical circuit.

During World War I, the stalemate of trench warfare during on the Western Front spurred the development of the tank. It was envisioned as an armoured machine that could advance under fire from enemy rifles and machine guns, and respond with its own heavy guns. It utilized caterpillar tracks to cross ground broken up by shellfire and trenches.

Chain track drive sprocket (Leclerc battle tank, 2006) In the case of vehicles with caterpillar tracks the engine-driven toothed-wheel transmitting motion to the tracks is known as the drive sprocket and may be positioned at the front or back of the vehicle, or in some cases both. There may also be a third sprocket, elevated, driving the track.

Bentley 2017, p. 111. For its re-appearance in "Crater 101", the Moonmobile model was fitted with a cargo module intended to store the Lunar Tractor. The script described the Lunar Tank as running on "ball tyres"; however, the miniature model used caterpillar tracks. The Moonmobile cockpit seats were a re-use of the Thunderbird 2 and 3 seats from the film Thunderbirds Are Go (1966).

Its principal weakness was its Holt caterpillar tracks. They were much too short in relation to the vehicle's length and heavy weight (23 tons). Later models attempted to rectify some of the tank's original flaws by installing wider and stronger track shoes, thicker frontal armour and the more effective 75mm Mle 1897 field gun. Altogether 400 Saint-Chamond tanks were built, including 48 unarmed caisson tanks.

An air ambulance from the University Medical Center Groningen attended. The Grove MZ 90 CR elevated work platform weighed 20 tonnes. Equipped with caterpillar tracks, it had a top speed of approximately . The platform had been parked on the south side of the railway line, and was to be driven to a point north of the railway where it was to be loaded onto a lorry.

For the firing of the gun and coaxial machine gun at night, the tank was equipped with two special projector-type headlamps, and a mask placed on the gun. Subsequently, these lights were retrofitted to earlier models of the tank. Improvements were also made to the drive wheels, caterpillar tracks and gearbox by 1938. In parallel with the main modification, 154 BT-7A artillery tanks were produced between 1936 and 1938.

OCC opted for their most radical design to date, an all-electric prone-rider tadpole trike with caterpillar tracks instead of wheels. James fielded one of his traditional hand-built choppers. On December 6, during a live edition of American Chopper, PJD and the T-51 Mustang bike won the online fan voting and was declared the winner of the buildoff. James came in second, with OCC coming in last.

In November 1915 Schwob was reappointed to the board of the Banque de l’Afrique occidentale (BAO). At the end of World War I (1914–18) he introduced Adolphe Kégresse, a specialist in caterpillar tracks, to Hinstin and Citroën. In December 1920 he became administrator of the Cie générale des colonies. He became president of the Société française pour le Commerce avec les Colonies et l’Etranger, the new name adopted by the Maison Gradis in 1921.

The operator's cab is on the east-facing front end, with most of the rest of the section housing the shovel's three steam engines and a boiler, no longer in working condition, with horizontal flues. A plate on its door bears the number 5304. An coal bin was added to the rear after it was built. The section rests on two pairs of caterpillar tracks, one pair out in front on a outrigger, the other in the middle.

On his return Brillié, who had earlier been involved in designing armoured cars for Spain, convinced the company management to initiate studies on the development of a Tracteur blindé et armé (armoured and armed tractor), based on the Baby Holt chassis, two of which were ordered. Experiments on the Holt caterpillar tracks started in May 1915 at the Schneider plant with a 75-hp wheel-directed model and the 45-hp integral caterpillar Baby Holt, showing the superiority of the latter.

After all these projects failed by June 1915, ideas of grandiose landships were abandoned, and a decision was taken to make an attempt with US Bullock Creeping Grip caterpillar tracks, by connecting two of them together to obtain an articulated chassis deemed necessary for manoeuvring. Experiments failed in tests made in July 1915. Another experiment was conducted with an American Killen-Strait tracked tractor. A wire-cutting mechanism was successfully fitted, but the trench-crossing capability of the vehicle proved insufficient.

Driving extra wheels meant more drive train weight, which required a larger and heavier engine to maintain performance. Even worse, none of the extra weight was put into an improvement of armour or armament carried, and the vehicles could still not cross very rough terrain. The adoption of caterpillar tracks offered a new solution to the problem. The tracks spread the weight of the vehicles over a much greater area, all of which was for traction to move the vehicle.

The results of the Baby Holt caterpillar were excellent, displaying remarkable mobility in the difficult terrain of Souain. The length of the Baby Holt however appeared to be too short to bridge German trenches, justifying the development of longer caterpillar tracks for the French tank project.Landships The Souain prototype could effectively bridge shell holes and trenches up to 1 meter in width, with a maximum limit of 1.20 meters, but required some support to bridge wider gaps, rendering it unsatisfactory as such.Gougaud, p.

The driver had insufficient time available to avoid the accident or retreat from the cab to a survival space within the train. Following the accident, vehicles with steel caterpillar tracks were prohibited from using level crossings in the Netherlands. One of the recommendations was that ProRail should look at the issue of drivers of large/slow vehicles being able to ascertain whether or not it was safe to cross a level crossing. ProRail has responded by stating that it is "embracing" the recommendations.

The 3-inch Gun M5 was the main weapon of towed Tank Destroyer Battalions. After the North African campaign, planners believed that towed guns were a better option than mobile units. This opinion changed in the months following the Normandy invasion in 1944. Tanks developed out the experiences of World War I, whereby the internal combustion engine was combined with steel armor plate, caterpillar tracks, cannons, and machine guns to produce a vehicle that could defeat the stalemate of trench warfare.

This deployment proved successful, with the vehicles being used in similar roles to those they had performed during the Vietnam War. However, the squadron had difficulty maintaining the M113s, particularly due to a shortage of links for their caterpillar tracks. After the withdrawal of 1 RAR, a ten man team from the Special Air Service Regiment which was deployed to Somalia in 1994 used two United Nations M113s. In April 1993 a civilian stole a M113 from an Army facility in Perth, and rampaged through the city for two hours.

The Type 1 Ho-Ha was based on the German Sd.Kfz. 251/1 (known popularly as Hanomag), the main armoured personnel carrier of the German Army, but did not use the overlapped and interleaved road wheels of the German design's suspension. Further, it had a "vertical rear plate with a door", akin to the American M3 Half-track; however, the door itself was a copy of the German "two-leaf" design. The Type 1 Ho-Ha had a pair of road wheels in front, supported by a pair of short caterpillar tracks to the rear.

Mercedes-Benz Unimog in the Dunes of Erg Chebbi in Morocco. Note the high ground clearance due to Portal gear axles An off-road vehicle is considered to be any type of vehicle which is capable of driving on and off paved or gravel surface. It is generally characterized by having large tires with deep, open treads, a flexible suspension, or even caterpillar tracks. Other vehicles that do not travel public streets or highways are generally termed off-highway vehicles, including tractors, forklifts, cranes, backhoes, bulldozers, and golf carts.

In December 1915, the influential Colonel Estienne made the Supreme Command very enthusiastic about the idea of creating an armoured force based on these vehicles; strong Army support for tanks would be a constant during the decades to come. Already in January and February 1916 quite substantial orders were made, at that moment with a total number of 800 much larger than the British ones. French Saint-Chamond tanks had long bodies with a lot of the vehicle projecting forward off of the short caterpillar tracks, making them more liable to get ditched in trenches.

During World War II, the median strips of some autobahns were paved over to allow their conversion into auxiliary airstrips. Aircraft were either stashed in numerous tunnels or camouflaged in nearby woods. However, for the most part during the war, the autobahns were not militarily significant. Motor vehicles, such as trucks, could not carry goods or troops as quickly or in as much bulk and in the same numbers as trains could, and the autobahns could not be used by tanks as their weight and caterpillar tracks damaged the road surface.

This was ideal for trench warfare, but made the tanks painfully slow in open battles. Their light cannons and machine-guns were usually unable to inflict serious damage on German vehicles. The exposed caterpillar tracks were easily broken by gunfire, and the Matilda tanks had a tendency to incinerate their crews if hit, as the petrol tanks were located on the top of the hull. By contrast the Infantry tank Matilda II fielded in lesser numbers was largely invulnerable to German gunfire and its gun was able to punch through the German tanks.

The library has room in the central tower for 180,000 volumes and room for over 1 million volumes in the underground book stacks. The library's collection, which is housed both in the library's main building and at Yale University's Library Shelving Facility in Hamden, Connecticut, totals roughly 1 million volumes and several million manuscripts. During the 1960s, the Claes Oldenburg sculpture Lipstick on Caterpillar Tracks (Ascending) was displayed in Hewitt Quadrangle. The sculpture has since been moved to the courtyard of Morse College, one of the university's residential dormitories.

A 1949 Bombardier B12 A J5 tractor and trailer, capable of snow or muskeg use Before the start of the company's development of track vehicles, Joseph-Armand Bombardier experimented with propeller-driven snow vehicles (similar to Russian aerosanis). His work with snowplane designs can be traced to before 1920. He quickly abandoned his efforts to develop a snowplane and turned his inventive skills to tracked vehicles. From the start, the company made truck-sized half-track vehicles, with skis in the front and caterpillar tracks in the rear, designed for the worst winter conditions of the flatland Canadian countryside.

All the horses of the Brigade, except those of the officers, have been withdrawn and sent to the Remount Department. The personnel of the Brigade are now being trained to drive and to repair the kind of tractors to be used. It is understood that a tractor fitted with caterpillar tracks has been officially recommended for the trials, which are to take place shortly in the Aldershot Command. It is urged in favour of mechanical draught that it is economical in man power since the personnel of a battery might be reduced to approximately one half, when compared with one relying on horse draught.

A Cat train is a train of one or more supply sleds/sleighs hauled by a continuous track vehicle, and is typically used in roadless areas. They are so named for the caterpillar tracks of the hauling vehicle. In northern climates, they were used to haul supplies to isolated communities in winter before engineers such as John Denison created modern winter roads which enabled standard winterized semi-trucks and trailers to haul these loads and heavier freight. Cat trains are still used in areas where winter roads cannot be built, such as along the Hudson Bay, as seen in Season 9 of Ice Road Truckers.

Mechanical construction Electrical aspect A level of programming There are many types of robots; they are used in many different environments and for many different uses. Although being very diverse in application and form, they all share three basic similarities when it comes to their construction: # Robots all have some kind of mechanical construction, a frame, form or shape designed to achieve a particular task. For example, a robot designed to travel across heavy dirt or mud, might use caterpillar tracks. The mechanical aspect is mostly the creator's solution to completing the assigned task and dealing with the physics of the environment around it.

Originally, the shell- proof tank was referred to simply as the Heavy Tank, then Foster's Battle Tank. Where the nickname 'Flying Elephant' came from no one knows for sure, though it was probably the result of the trunk-like nose gun, domed front, and enormous bulk combined with a traditional British lightheartedness. Another view of the model at The Tank Museum, UK. The tank was fitted with two pairs of caterpillar tracks. The outer tracks resembled those of the Mark I, but were flatter and 61 centimetres wide, while a pair of additional, narrower tracks were fitted to the underside approximately 6 inches higher than the main tracks.

There was a convertible version developed for the Australian market. It was also successful in Cuba where it was one of the best-selling cars of its time and an estimated 10.000 still exist today. Throughout the 1980s, there were several experimental prototypes developed in Poland. A cargo version called "Bombel" (literally "bubble", but also a colloquial term for "small child") because of its fibreglass bubble- shaped cargo area; an off-road version propelled by caterpillar tracks and a front wheel drive, front engined model, with a longer front end and a flat cargo area in the rear where the original 126 had its engine.

On his return, Brillié, who had earlier been involved in designing armoured cars for Spain, apparently without mentioning being influenced in this by Quellennec, convinced the company management to initiate studies on the development of an armoured fighting vehicle, based on the Baby Holt chassis, two of which were ordered. The type was intended to be sold to the French Cavalry. Experiments on the Holt caterpillar tracks started in May 1915 at the Schneider plant with a 75 hp wheel-directed model and the 45 hp integral caterpillar Baby Holt, showing the superiority of the latter. The Castéran and the Killen-Strait Tractor were also tested but rejected.

The limitation on armour and firepower was no longer the ground pressure but the power and weight of the power-plant. Swinton (now Colonel) with Benjamin Holt in Stockton, California, relays gratitude to the inventor for his company's contribution to the war effort. The remaining issue was how to use and configure a vehicle. Major Ernest Dunlop Swinton of the Royal Engineers was the official British war correspondent serving in France in 1914 and recounted in his book Eyewitness how the idea of using caterpillar tracks to drive an armoured fighting vehicle came to him on October 19, 1914 while he was driving through northern France.

The metallic- blue, tank-like SPV serves as Spectrum's primary armoured interceptor ground vehicle. It is long, weighs eight tons, and has a maximum speed of either on land. It is fitted with five pairs of wheels (the three over the front, middle and rear axles constituting the main drive), with additional traction for mountainous environments provided by rear-mounted, hydraulically-lowered caterpillar tracks. Within the hermetically-sealed control compartment, the driver, co-driver and a passenger are seated backwards, facing the rear, to reduce the possibility of injury in the event of a crash; the driver is aided by a video monitor displaying (vertically-flipped) forward and rear views.

The British Ice Challenger exploration team used a screw drive in their Snowbird 6 vehicle (a modified Bombardier tracked craft) to traverse the ice floes in the Bering Strait. The rotating cylinders allowed Snowbird 6 to move over ice and to propel itself through water, but the screw system was not considered suitable for long distances, and the cylinders could be raised so that the vehicle could also run on conventional caterpillar tracks. The Ice Challenger website says that the design was inspired by a Russian vehicle used to pick up cosmonauts who landed in Siberia (perhaps the ZIL-2906). Russian inventor Alexey Burdin has come up with a screw-propulsion system "TESH-drive Transformable worms".

At the surface the MEV extends caterpillar tracks to negotiate the rocky terrain.Thunderbirds Are Go (1966), Century 21 Cinema/United Artists. The concept of a reusable first-stage lifting body (or in this case, bodies) boosting a smaller spacecraft to high altitude for more efficient use of its propulsion was in direct competition with the vertical-ascent rocket doctrine of the 1960s as a means of achieving spaceflight, and for some time lost out to it, as even the Space Shuttlewhich landed as a conventional aircraftmakes a vertical rocket-powered ascent in the "classical" manner. In more recent years Virgin Galactic have re-established the concept, providing the first private commercial suborbital spaceflights in a similarly launched vehicle.

There is a monument in Wentworth at the junction of the Darling and Murray Rivers in Australia commemorating the time in 1956 when both rivers flooded and a fleet of little grey Fergies was used to build levee banks to save the town. Commonwealth Trans-Antarctic Expedition A fleet of seven Ferguson TE-20s was used on the 1955–58 Commonwealth Trans-Antarctic Expedition which was led by Edmund Hillary. Four petrol-engined and three diesel models were used. Some were supplied as half-tracks, with steerable front skis, whilst others of the New Zealand team were fitted with an extra wheel on each side and full caterpillar tracks, developed by the expedition in the Antarctic.

The prefabricated movie set of the sandcrawler was shipped from England and took special effects genius John Stears and his crew four days to move it thirty miles into the Tunisian desert. It was two stories tall and ninety feet long when it was fully assembled, with the caterpillar tracks being almost twice as tall as a person, and covered in sand and mud to give them a "used" look. The night before the scene with the Jawas was to be shot, a sandstorm blew apart the set, and it took a day to put it back together and an additional day to shoot the scene. Afterwards, it was transformed into a burned-out hulk, taking another day.

The Renault FT, the first "modern" tank to enter production French development into tanks began during World War I as an effort to overcome the stalemate of trench warfare, and largely at the initiative of the manufacturers. The Schneider CA1 was the first tank produced by France, and 400 units were built. The French also experimented with various tank designs, such as the Frot- Laffly landship, Boirault machine and Souain experiment. Another 400 Saint- Chamond tanks were manufactured from April 1917 to July 1918, however these tanks were largely underpowered and of limited utility due to the design of the caterpillar tracks, which were too short in comparison with the tank's length and weight.

An improved cooling system and a new lightweight suspension was fitted, featuring hollow metallic wheels of a small diameter and caterpillar tracks with rubber joints. The tank would be armed with the D-54TS and frontal armour of 120 mm. As it did not present a clear superiority in terms of combat characteristics when compared to the T-55, which was entering active service, Morozov decided that production was not yet ready given the project's drawbacks. However, studies conducted on the obyekt 430U, featuring a 122 mm gun and 160 mm of armour, demonstrated that the tank had the potential to fit the firepower and armour of a heavy tank on to a medium tank chassis.

Whilst several experimental machines were investigated in France, it was a colonel of artillery, J.B.E. Estienne, who directly approached the Commander-in-Chief with detailed plans for a tank on caterpillar tracks, in late 1915. The result was two largely unsatisfactory types of tank, 400 each of the Schneider and Saint-Chamond, both based on the Holt Tractor. The following year, the French pioneered the use of a full 360° rotation turret in a tank for the first time, with the creation of the Renault FT light tank, with the turret containing the tank's main armament. In addition to the traversible turret, another innovative feature of the FT was its engine located at the rear.

Also the T-41 amphibious tank was also produced, with the chassis, in part, borrowed from the T-33, and the caterpillar tracks entirely from the T-27 tank. The multi- turreted T-35 heavy tank also showed flaws; Soviet tank designers started drawing up replacements. The T-35 conformed to the 1920s notion of a 'breakthrough tank' with very heavy firepower and armour protection, but poor mobility. The Spanish Civil War demonstrated the need for much heavier armour on tanks, and was the main influence on Soviet tank design just prior to World War II. Of the tanks produced between 1930 and 1940, 97% were either identical copies of foreign designs, or very closely related improvements.

The Aerosani, propeller-driven and running on skis, was built in 1909–1910 by Russian inventor Igor Sikorsky of helicopter fame. Aerosanis were used by the Soviet Red Army during the Winter War and World War II. There is some dispute over whether Aerosanis count as snowmobiles because they were not propelled by tracks.On this site, they tell you to go to Snowmobile when you search for Aerosani Adolphe Kégresse designed an original caterpillar tracks system, called the Kégresse track, while working for Tsar Nicholas II of Russia between 1906 and 1916. These used a flexible belt rather than interlocking metal segments and could be fitted to a conventional car or truck to turn it into a half-track, suitable for use over soft ground, including snow.

The Bajac agricultural tractor however proved not mobile enough — the initial experiment had only tested the wire-cutting ability — and had the severe disadvantage of having to approach the enemy lines driving backwards. Breton and Prétot then considered using some of the two hundred American four-wheel drive Jeffery tractors that had been commanded by the French Artillery. When this was refused, Commandant Boissin directed Breton to the Schneider company which was working on the caterpillar track system, under a production licence from the American Holt Manufacturing Company. Experiments with the Holt caterpillar tracks had started in May 1915 at the Schneider plant with a 75 hp wheel- directed model and the 45 hp integral caterpillar Baby Holt, showing the superiority of the latter.

Most cities thus have at least twice as many plows as trucks. Smaller narrow body plows, with Caterpillar tracks or huge snow tires salt and clear sidewalks in some cities, but in many others with less snowfall and/or less pedestrian traffic individuals are tasked with clearing the sidewalk in front of their homes. Ecological movements often oppose this use of salt because of the damage it does when it eventually washes off the roads and spreads to the environment in general. Credit for the concept that municipalities should remove snow from public roadways usually goes to Edward N. Hines, a celebrated early 20th century transportation thinker who also was the first to put a painted center line stripe on an automobile-era road.

A Delaunay-Belleville armoured car body was fitted, making the Killen-Strait machine the first armoured tracked vehicle, but the project was abandoned as it turned out to be a blind alley, unable to fulfil all-terrain warfare requirements. After these experiments, the Committee decided to build a smaller experimental landship, equivalent to one half the articulated version, and using lengthened US-made Bullock Creeping Grip caterpillar tracks. This new experimental machine was called the No1 Lincoln Machine: construction started on 11 August 1915, with the first trials starting on 10 September 1915. These trials failed however because of unsatisfactory tracks. Development continued with new, re-engineered tracks designed by William Tritton, and the machine, now renamed Little Willie, was completed in December 1915 and tested on 3 December 1915.

The length of the Baby Holt however appeared to be too short to bridge German trenches, justifying the development of longer caterpillar tracks for the French tank project.. For Estienne the vehicle shown embodied concepts about armoured fighting vehicles which he had been advocating since August 1914. Already on 1 December Estienne had proposed to the French GHQ the use of tracked armoured tractors to move infantry, equipment and cannon over the battlefield, having performed some trials with British caterpillar tractors.. On 11 December Estienne let a certain lieutenant Thibier draw a sketch of two conceptions: the one of a Baby Holt chassis fitted at the front and the back with auxiliary rollers, to improve the trench-crossing capacity; the other of an elongated suspension protected by side armour.

In January 1915, the French arms manufacturer Schneider sent out its chief designer, Eugène Brillié, to investigate tracked tractors from the American Holt Company, at that time participating in a test programme in England. The original French project was to provide mobility to mechanical wire-cutting machines of the Breton-Pretot type. On his return Brillié, who had earlier been involved in designing armoured cars for Spain, convinced the company management to initiate studies on the development of a Tracteur blindé et armé ("armoured and armed tractor"), based on the Baby Holt chassis, two of which were ordered. Experiments on the Holt caterpillar tracks started in May 1915 at the Schneider plant with a 75 hp wheel-steered model and the 45 hp all-caterpillar Baby Holt, showing the superiority of the latter.

In 1903, H. G. Wells published the short story "The Land Ironclads," positing indomitable war machines that would bring a new age of land warfare, the way steam-powered ironclad warships had ended the age of sail. Wells' literary vision was realized in 1916, when, amidst the pyrrhic standstill of the Great War, the British Landships Committee, deployed revolutionary armoured vehicles to break the stalemate. The tank was envisioned as an armoured machine that could cross ground under fire from machine guns and reply with its own mounted machine guns and cannons. These first British heavy tanks of World War I moved on caterpillar tracks that had substantially lower ground pressure than wheeled vehicles, enabling them to pass the muddy, pocked terrain and slit trenches of the Battle of the Somme.

The development of tanks in World War I began as an attempt to break the stalemate which trench warfare had brought to the Western Front. The British and French both began experimenting in 1915, and deployed tanks in battle from 1916 and 1917 respectively. The Germans, on the other hand, were slower to develop tanks, concentrating on anti-tank weapons. The German response to the modest initial successes of the Allied tanks was the A7V, which, like some other tanks of the period, was based on caterpillar tracks of the type found on the American Holt Tractors. Initially unconvinced that tanks were a serious threat, the High Command ordered just twenty A7Vs, which took part in a handful of actions between March and October, 1918. They suffered from numerous design faults, and Germany actually used more captured British tanks than A7Vs.

At the time the Government owned two hotels, the Hotel Kosciusko at Diggers Creek and the Chalet at Charlotte's Pass and, between the two, a much smaller lodge, Betts Camp. The Government realised that it could not keep up with the booming post- war interest in skiing and decided to allow ski clubs to build their own accommodation. The first clubs to build were Kosciusko Snow Revellers Club in Perisher Valley (1950), Ski Tourers Association at Lake Albina (1951), KAC at Charlotte's Pass (1952) and Telemark Ski Club in Perisher Valley (1952). In 1953 a syndicate of KAC members formed the Alpine Transport Company (ATC) to start an oversnow transport service, based at Smiggin Holes, for skiers and goods in Perisher Valley.KAC Bulletin (1953) September, p.12 ATC used ex World War II M. 29 Cargo Carriers ("Weasels") with caterpillar tracks.

However, he is also something of a coward, preferring softer targets that he can inflict more pain upon while chanting his catchphrase: "Big jobs!" He has no compunctions about massacring humans, evidenced in The Third Element when he is annoyed about having missed most of a battle because of the time it took to remove all the "human gristle" clogging his caterpillar tracks. In his early stories he openly loathed Hammerstein and Ro-Jaws (as a result of their time in Ro- Busters), but later this hatred was toned down to a general dislike of everything and everybody except videos of chainsaw torture. Despite this Mek- Quake is eager to show his intelligence and importance, and in Kronicles of Khaos he kept trying to join in at the end of Deadlock's statements so he could seem like he was already versed in Khaos.

Claes Oldenburg Museum of Modern Art, New York. In 1967, New York city cultural adviser Sam Green realized Oldenburg's first outdoor public monument; Placid Civic Monument took the form of a Conceptual performance/action behind the Metropolitan Museum of Art, New York, with a crew of gravediggers digging a 6-by-3-foot rectangular hole in the ground. In 1969, Oldenberg contributed a drawing to the Moon Museum. Geometric Mouse- Scale A, Black 1/6, also from 1969, was selected to be part of the Governor Nelson A. Rockefeller Empire State Plaza Art Collection in Albany, NY. Many of Oldenburg's large-scale sculptures of mundane objects elicited ridicule before being accepted. For example, the 1969 Lipstick (Ascending) on Caterpillar Tracks, was removed from its original place in Beinecke Plaza at Yale University, and "circulated on a loan basis to other campuses".

Before 1914, inventors had designed armoured fighting vehicles and one had been rejected by the Austro-Hungarian army in 1911. In 1912, L. E. de Mole submitted plans to the War Office for a machine which foreshadowed the tank of 1916, that was also rejected and in Berlin an inventor demonstrated a land cruiser in 1913. By 1908, the British army had adopted vehicles with caterpillar tracks to move heavy artillery and in France, Major E. D. Swinton RE heard of the cross-country, caterpillar-tracked Holt tractor in June 1914. In October, Swinton thought of a machine-gun destroyer, that could cross barbed wire and trenches and at GHQ discussed it with Major-General G. H. Fowke, the army chief engineer, who passed this on to Lieutenant-Colonel Maurice Hankey, the Secretary of the War Council but this had evoked little interest by January 1915.

It was the sight of them in use by the British that later inspired Estienne to have plans drawn up for an armoured body on caterpillar tracks.

For instance, there is a long- lived story that, back in the 1970s, if all seven draglines at Peak Downs Mine (a very large BHP coal mine in central Queensland, Australia) turned simultaneously, they would black out all of North Queensland. However even now, if they have been shut down, they are always restarted one at a time due to the immense power requirements of startup. "Walking" dragline animation based on Martinson's patent of 1926 In all but the smallest of draglines, movement is accomplished by "walking" using feet or pontoons, as caterpillar tracks place too much pressure on the ground, and have great difficulty under the immense weight of the dragline. Maximum speed is only at most a few metres per minute,"Maid Marian's journey becomes a 'drag'" The Daily Gleaner (10 October 2008) accessed 1 November 2008] since the feet must be repositioned for each step.

French Saint-Chamond tanks had long bodies with a lot of the vehicle projecting forward off of the short caterpillar tracks, making them more liable to get ditched in trenches. Army enthusiasm and haste had its immediate drawbacks however. As a result of the involvement of inexperienced army officers ordered to devise a new tank based on the larger 75 hp Holt chassis in a very short period of time, the first French tanks were poorly designed with respect to the need to cross trenches and did not take the sponson-mounting route of the British tanks. The first, the Char Schneider CA equipped with a short 75 mm howitzer, had poor mobility due to a short track length combined with a hull that overhung front and rear. It was unreliable as well; a maximum of only about 130 of the 400 built were ever operational at the same time.

Within the development process, the Kung Feng VI was initially planned to be placed on top of an M42 Duster chassis, however due to difficulties in procurement the M113 chassis was used instead, which was unable to properly bear the weight of the rocket system. Henceforth, the ROC army gave up on the prospects of implementing the Kung Feng VI on caterpillar tracks, and began working on placing them on M809 five tonne wheeled trucks, in addition to implementing the FAC-202R fire control apparatus in order to improve precision. The ROC armed forces quickly retired its Kung Feng IV launchers and replaced them with the newer VI model as it entered service, however at the same time the launchers were incapable of fast reloading and had no dedicated transport trailer. Upon firing, it took soldiers 15 minutes to manually load the next rockets before the Kung Feng VI could fire again.

Sprung and unsprung mass are shown Sprung mass (or sprung weight), in a vehicle with a suspension, such as an automobile, motorcycle, or a tank, is the portion of the vehicle's total mass that is supported by the suspension, including in most applications approximately half of the weight of the suspension itself. The sprung mass typically includes the body, frame, the internal components, passengers, and cargo, but does not include the mass of the components at the other end of the suspension components (including the wheels, wheel bearings, brake rotors, calipers, and/or continuous tracks (also called caterpillar tracks), if any), which are part of the vehicle's unsprung mass. The larger the ratio of sprung mass to unsprung mass, the less the body and vehicle occupants are affected by bumps, dips, and other surface imperfections such as small bridges. However, a large sprung mass to unsprung mass ratio can also be deleterious to vehicle control.

Jules-Louis Breton (1872-1940) The Breton-Prétot machine was a saw designed to cut the barbed wire protecting enemy trenches of World War I. The first version consisted of a small circular saw, driven by a six hp engine, attached to a long lever that was placed on a small cart with four wheels, that had to be pushed towards its objective. Breton proposed the machine to the French government in November 1914 and a prototype was tried in January 1915, when it was shown that the system in this form had little practicality. The use of caterpillar tracks was discussed that same month, but since none was available at that time, the system was then mounted at Liancourt on the back of a Bajac tractor in an attempt to obtain all-terrain mobility, towards the end of February 1915. The small circular saw was replaced by a large vertical saw with thirteen teeth, but a larger horizontal circular saw was added, just above ground level to cut the barbed-wire poles.
