Caterpillar Inc. is an American corporation which designs, develops, engineers, produces, markets and sells machinery, engines, financial products and insurance to customers via a worldwide dealer network. 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, the California-based Caterpillar Tractor Company. In 1986, the company re-organized itself as a Delaware corporation under the current name, Caterpillar Inc. The history of Caterpillar is all about doing: creating, building, problem solving, innovating, testing, servicing and improving. The company also licenses and markets a line of clothing and workwear boots under its Cat / Caterpillar name. Caterpillar machinery is recognizable by its trademark "Caterpillar Yellow" livery and the "CAT" logo.



In 1890s and early 1900s, the steam tractors were extremely heavy, they sometimes weighing 1,000 pounds (450 kg) per horsepower, and often sank into the rich, soft earth of the San Joaquin Valley Delta farmland surrounding Stockton, California. Benjamin Holt tried many attempts to fix the problem by increasing the size and width of the wheels up to 7.5 feet (2.3 m) tall and 6 feet (1.8 m) wide, producing a tractor 46 feet (14 m) wide. Also, there was another solution considered was to lay a temporary plank road ahead of the steam tractor, but this was time-consuming, expensive, and interfered with earthmoving. The photographer of the company observed that the tractor crawled like a caterpillar, so Holt seized on the metaphor. "Caterpillar it is". Holt received the first patent for a practical continuous track for use with a tractor on December 7, 1907 for his improved "Traction Engine".

Holt's track-type tractors played a support role in World War I. Even before the U.S. formally entered World War I, Holt had shipped 1,200 tractors to England, France and Russia for agricultural purposes. These governments, sent the tractors directly to the battlefront where the military put them to work hauling artillery and supplies. When World War I broke out, the British War Office ordered a Holt tractor and put it through trials at Aldershot. The War Office was suitably impressed and chose it as a gun-tractor. Over the next four years, the Holt tractor became a major artillery tractor, mainly used to haul medium guns like the 6-inch howitzer, the 60-pounder, and later the 9.2-inch howitzer. Holt tractors were also the inspiration for the development of the British tank, which profoundly altered ground warfare tactics.

During World War I Holt tractors had become well known in the market. Military contracts formed the major part of the company's production. The heavy-duty tractors needed by the military were unsuitable for farmers. The company's situation worsened when artillery tractors were returned from Europe, depressing prices for new equipment and Holt's unsold inventory of military tractors. C. L. Best Gas Tractor Company, formed by Clarence Leo Best in 1910 and Holt's primary competitor, had during the war received government support enabling it to supply farmers with the smaller agricultural tractors they needed. Best also assumed considerable debt to allow it to continue expansion, especially production of its new Best Model 60 "Tracklayer".


Business Lines of Caterpillar

Machinery :

Caterpillar's line of machines range from tracked tractors to hydraulic excavators, backhoe loaders, motor graders, off-highway trucks, wheel loaders, agricultural tractors and locomotives. Caterpillar has a list of around 400 products for purchase through its dealer network. Caterpillar is the world's largest manufacturer of wheel loaders. he medium size (MWL) and large size (LWL) are designed at their Aurora, Illinois facility. Large wheel loaders are produced in the United States on three separate assembly lines at Aurora, Illinois. Medium wheel loaders are manufactured at: Aurora, Illinois; Sagamihara, Kanagawa, Japan; Gosselies, Charleroi, Belgium; Piracicaba, São Paulo, Brazil; India and the People's Republic of China.


On-Road Trucks :

In 2011, Caterpillar began selling a line of on-road trucks. The CAT VT600, is a Class 8 vocational truck, the truck is offered with a CAT 11 liter CT11 and 13 liter CT13 and is built at Navistar International’s factory in Garland, Texas. As of March 2016, Caterpillar has ceased production of on-highway vocational trucks.


Engines and Gas Turbines :

In 1997, Caterpillar introduced the inline 6 cylinder 7.2 litre Caterpillar 3126 engine as its first electronic diesel engine for light trucks and buses. In the next year, the 3126B version of the engine was introduced through which  Caterpillar decreased emissions and noise. Further in 2002, the introduction of the 3126E, which had an improved high-pressure oil pump and improved electronics. In 2003 Caterpillar started selling a new version of 3126E engine called the C7 to meet increased United States emission standards. C7 had the same overall design as the 3126 version but C7 comes with the improved fuel injectors and electronics which included its new Advanced Combustion Emissions Reduction Technology (ACERT) system. Caterpillar updated the C7 to use common rail fuel injectors and improved ACERT electronics in the year 2007.


Caterpillar Defense Products :

The division, Caterpillar Defense Products provides both propulsion engines and power generation systems to the naval shipbuilding industry, such as the Series 3512B turbocharged V-12 diesel engine for American Virginia class nuclear submarines. Israel buys bulldozers for the Israel Defense Forces (IDF) from Caterpillar through the U.S. government foreign aid money in their civilian configuration. The military modifications and the installment of vehicle armor are done entirely in Israel by the IDF and Israeli security contractors. The IDF uses many Caterpillar machines like, bulldozers, excavators, wheel loaders and graders mainly for engineering, earthworks and building projects. The Israel Defense Forces' use of highly modified Caterpillar D9 bulldozers has led to Caterpillar being criticized by activists and some shareholders.



Agricultural Products :

Challenger is the product range of agricultural tractors produced by Caterpillar. The program started in the 1970s and involved both D6-based units and Grader power units. A parallel program was also developing wheeled high hp tractors based on using the articulated loading shovel chassis was latter merged with the crawler team. The result was the Challenger Tractor and the "Mobi-Trac" system. Since 1997, the Challenger has been marketed in Europe as Claas machines. Claas and Caterpillar formed a joint venture, Claas Omaha, to build combine harvesters.
