Caterpillar D10
The Caterpillar D10 is a track-type tractor manufactured by Caterpillar Inc. (then called the Caterpillar Tractor Company). It was the first modern tractor to use the elevated drive sprocket to improve durability, operator comfort, and ease of maintenance. History The Caterpillar D10 was the result of a need for a tractor larger than the Caterpillar D9. At this time, competitors were building bulldozers that were more powerful than the D9. Allis Chalmers introduced at Conexpo 69 in Chicago a HD-41 which was the largest crawler in the world. In 1974 after AC and Fiat merged their construction equipment divisions the 41-B was introduced. For example, the Fiat-Allis 41-B track-type tractor had at the time, while the D9H had . In 1976 Japanese company Komatsu came out with an even larger bulldozer called the D455A at and . The first pilot D10 was D10X1 and was shown in July 1973 at a big Caterpillar corporate meeting. Other prototypes would follow in 1975 and 1977. In March 1 ...

Caterpillar Track
Continuous track is a system of vehicle propulsion used in tracked vehicles, running on a continuous band of treads or track plates driven by two or more wheels. The large surface area of the tracks distributes the weight of the vehicle better than steel or rubber tires on an equivalent vehicle, enabling continuous tracked vehicles to traverse soft ground with less likelihood of becoming stuck due to sinking. Modern continuous tracks can be made with soft belts of synthetic rubber, reinforced with steel wires, in the case of lighter agricultural machinery. The more common classical type is a solid chain track made of steel plates (with or without rubber pads), also called caterpillar tread or tank tread, which is preferred for robust and heavy construction vehicles and military vehicles. The prominent treads of the metal plates are both hard-wearing and damage resistant, especially in comparison to rubber tyres. The aggressive treads of the tracks provide good trac ...

Caterpillar Inc
Caterpillar Inc. (stock symbol CAT) is an American Fortune 100, ''Fortune'' 500 corporation and the world's largest construction-equipment manufacturer. In 2018, Caterpillar was ranked number 65 on the ''Fortune'' 500 list and number 238 on the Global ''Fortune'' 500 list. Caterpillar stock is a component of the Dow Jones Industrial Average. Caterpillar Inc. traces its origins to the 1925 merger of the Holt Manufacturing Company and the C. L. Best Tractor Company, creating a new entity, California-based Caterpillar Tractor Company. In 1986, the company reorganized itself as a Delaware corporation under the current name, Caterpillar Inc. It announced in January 2017 that over the course of that year, it would relocate its headquarters from Peoria, Illinois, to Deerfield, Illinois, scrapping plans from 2015 of building an $800 million new headquarters complex in downtown Peoria. Its headquarters are located in Irving, Texas, since 2022. The company also licenses and markets a li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drive Sprocket
A sprocket, sprocket-wheel or chainwheel is a profiled wheel with teeth that mesh with a chain, track or other perforated or indented material. The name 'sprocket' applies generally to any wheel upon which radial projections engage a chain passing over it. It is distinguished from a gear in that sprockets are never meshed together directly, and differs from a pulley in that sprockets have teeth and pulleys are smooth except for timing pulleys used with toothed belts. Sprockets are used in bicycles, motorcycles, tracked vehicles, and other machinery either to transmit rotary motion between two shafts where gears are unsuitable or to impart linear motion to a track, tape etc. Perhaps the most common form of sprocket may be found in the bicycle, in which the pedal shaft carries a large sprocket-wheel, which drives a chain, which, in turn, drives a small sprocket on the axle of the rear wheel. Early automobiles were also largely driven by sprocket and chain mechanism, a pract ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caterpillar D9
The Caterpillar D9 is a large track-type tractor designed and manufactured by Caterpillar Inc. It is usually sold as a bulldozer equipped with a detachable large blade and a rear ripper attachment. The D9, with 354 kW (474 hp) of gross power and an operating weight of , is in the upper end of Caterpillar's track-type tractors, which range in size from the D3 57 kW (77 hp), , to the D11 698 kW (935 hp), . The size, durability, reliability, and low operating costs have made the D9 one of the most popular large track-type tractors in the world. Engineering and technical description The D9 is a series of heavy tracked-type tractors, carried on continuous tracks and usually used as bulldozers. The series began in 1954 with a prototype tractor called the D9X. Ten D9X prototype models were built in 1954. In 1955, the D9 was introduced to compete against the more powerful Euclid TC-12. The D9 came equipped with a 1,473 cid D353, which powered the D9 until th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Komatsu Limited
or () is a Japanese multinational corporation that manufactures construction, mining, forestry and military equipment, as well as diesel engines and industrial equipment like press machines, lasers and thermoelectric generators. Its headquarters are in Minato, Tokyo, Japan. The corporation was named after the city of Komatsu, Ishikawa Prefecture, where the company was founded in 1921. Worldwide, the Komatsu Group consists of Komatsu Ltd. and 258 other companies (215 consolidated subsidiaries and 42 companies accounted for by the equity method).

Fiat-Allis
Fiatallis (1983 to early 2000s, Fiat-Allis 1974 to 1982), was a brand of heavy equipment (also called construction equipment, earthmoving equipment, or engineering vehicles), such as loaders, bulldozers, backhoes, scrapers, and graders. It began in January 1974, when Allis-Chalmers's construction equipment business was reorganized into a joint venture with Fiat SpA,.. which bought a 65% majority stake at the outset. Allis-Chalmers's construction equipment business was often unprofitable during the 1950s and 1960s. It faced stiff competition from companies such as Caterpillar, Case, International Harvester, Euclid, John Deere, Fiat MMT, and several others. The 1974 formation of a new company, Fiat-Allis Construction Machinery Inc., was essentially a divestment for Allis-Chalmers so that capital could be redirected to their other more profitable divisions. In December 1980, Fiat-Allis Construction Machinery Inc. announced they would be closing the former Tractomotive wheel loade ...

Caterpillar D11
The Caterpillar D11T is a large bulldozer, manufactured by Caterpillar Inc. in East Peoria, Illinois, and mainly used in the mining industry. Primarily designed as a bulldozer, it is also used for push-loading scrapers, and ripping rock overburden. History D11N The D11N was introduced in February 1986 to replace the D10. The D11N had some major improvements over the D10: it includes a bigger track and blade, and a longer track by . The U blade was just under long and high. This increased the blade capacity to . The D11N's weight was . It was powered by a , 3508 V-8 diesel engine. The D11N's improvements made it over 10 percent more productive than the D10. In 1987 a hydraulically powered impact ripper was added to the D11N which raised the weight up to . This would become known as the D11N Impact Ripper. D11R & D11R Carrydozer The D11R and D11R Carrydozer were introduced in Las Vegas, Nevada, at MINExpo International in 1996. Both were and that would be increased to later i ...

Heavy Equipment
Heavy equipment or heavy machinery refers to heavy-duty vehicles specially designed to execute construction tasks, most frequently involving earthwork operations or other large construction tasks. ''Heavy equipment'' usually comprises five equipment systems: the implement, traction, structure, power train, and control/information. Heavy equipment has been used since at least the 1st century BC when the ancient Roman engineer Vitruvius described a crane in ''De architectura'' when it was powered via human or animal labor. Heavy equipment functions through the mechanical advantage of a simple machine, the ratio between input force applied and force exerted is multiplied, making tasks which could take hundreds of people and weeks of labor without heavy equipment far less intensive in nature. Some equipment uses hydraulic drives as a primary source of motion. The term "plant" is used to refer to any mobile type of heavy machinery. History The use of heavy equipment has ...
