Caterpillar R4 Dozer

Caterpillar is the best known manufacturer of construction equipment in the world (probably). The company was formed in 1925 by the merger of The Holt Company, (who built its first crawler machine in 1904), and the company of C.L.Best who started producing Crawler machines in 1913. The new company was then called The Caterpillar Tractor Company. Caterpillar became synonymous with crawler type machines.

Both Best and Holt started as farm machinery manufactures.

Best Edit

Best Invented a portable grain cleaner in 1871, soon followed by a combine harvester. In 1890 the company purchased the rights to manufacture the Remington steam engine and produced a range of steam-driven farm machinery, including steam tractors and combine harvesters. Best Manufacturing was bought by Holt in 1908.

C.L. Best, the son of the founder then formed his own rival company, the "C. L. Best Gas Traction Company" which built gasoline-powered tractors. This new company acquired the rights to manufacture the Lombard Log Hauler, an early tracked crawler, and began producing "tracklayer" tractors

Holt Edit

The Holt 70hp was a 3 wheeled Mechanical tractor built in 1905. In 1905 Holt built the No.77 with tracks in place of wheels. It was originally built as a wheeled machine in 1904. By 1908 Holt was building the Holt 40 a 25hp gas powered crawler tractor. The second one sold was No. 1004 and is today in preserved in America. Holt aquired Best manufacturing 1908. In 1925 merged with C.L. Best Gas Traction company to form what was to come Caterpillar.


1925 Edit

The Birth of the Caterpillar Company. The First models were from the old companies, but renamed as;

  • Caterpillar 30 (from Best)
  • Caterpillar 60 (from Best)
  • Caterpillar 2-ton (from Holt)
  • Caterpillar 5-ton (from Holt)
  • Caterpillar 10-ton (from Holt) this was dropped in late 1925 in favour of the 60
  • Cat 15
  • Cat 20
  • Cat 22
  • Cat 25

In 1928 they Took over the Russell Grader Manufacturing Co. to add a line of graders, dropping models using competitors tractors for power units.

  • Model 10 grader
  • Model 15 grader
  • Model 20 grader

1930's - The Diesel era begins Edit

  • Cat 60 / 65
  • Cat 35
  • Cat 40
  • Cat 50
  • Cat 65 (1d)
  • cat 65 (2d)
  • Cat 70 (8d)
  • cat 70 (1E)
  • Model 112 grader introduced 1939
  • Model 212 grader introduced 1939

The War years Edit

(WORK IN PROGRESS) During the war most of the output is for the Government and large numbers of machines were shipped abroad to the UK under Lend-lease, or shipped out to the Far East to assist in the retaking of the islands from the Japanese and build Airfields and harbors.This made them number one.

1940s - Earth moving beginsEdit

After the war the US Government started the Interstate program of road building, and in the UK rebuilding work and the start of the Motorways program requiring large numbers of earth moving machines, with contractors buying up army surplus machines. (Details require adding)

1950sEdit

  • Caterpillar 944A traxcavator 2cu yd Loading shovel introduced in 1959.
  • Caterpillar 212 Grader ( S.E. Davis & Son Ltd. of Redditch has one in their collection of preserved machines).

1960sEdit

1963 saw the first off highway dump truck launched, the model 769 with a 35 ton capacity.

1970sEdit

1974 saw the Introduction of Articulated Dumper Trucks (ADT) built by DJB in Peterlee, England. These were based on a full Cat Drive train, and after a license agreement Cat bought a share of company for the rights to the designs in 1985 and the company changed name to Artix Ltd. By 1996 they bought the whole company out.[6]

1980sEdit

  • Challenger Tracked Tractor created. It brought tracks back to the fields after a steady decline. Since the 60's, tractor horse power steadily increased and the versatility of tires for transport out wieghed the advantages of increased traction from tracks.

The increase in open pit mining and the availability of high powered hydraulics lead to the growth in hydraulic excavators and an increase in the size of mining dump trucks. Expansion in the 60s was halted by the 70s energy crisis and recession, along with the need to replace machines which in some cases dated from the 1940s.

The Mining Giants CreatedEdit

In the 1980s CAT decided to start building 100+ ton dump trucks to compete with Terex and Euclid. They built a proto-type model Cat 785 in 1983 and started testing of the 130 ton capacity dump truck. The machine followed the lines of the successful Cat 777 line of trucks but with greater capacity.

21st century and the futureEdit

Some product lines dropped, but others join the range as global expansion continues.

At Minexpo 2008 in Las Vegas Caterpillar launched some new models;

  • Cat 795F AC - 345 ton capacity Diesel-electric drive dump truck.
  • Cat 993K 16-19 yd wheeled loader, with a 1050 hp Caterpillar C32 engine.
  • Cat D11T Bulldozer.
  • Cat AD55B - 60 ton capacity articulated dump truck (ADT)

In 2009, Caterpillar and Navistar announced the formation of a new 50/50 joint venture to be called NC2 Global. Based in Chicago, IL, this company is to "develop, manufacture and distribute commercial trucks globally, outside North America and India" under the International and Cat brands.[7]

In 2010 Caterpillar announced that they were acquiring Bucyrus who had inturn had recently acquired the heavy excavator division of Terex, that was based on the former O&K RH excavtor range. This strategic move has given Caterpillar a major force in Mining excavator production to go with the existing dump truck line and offer their clients a range of large hydraulic or cable operated shovels.

DealersEdit

Main article: List of Caterpillar dealerships

Caterpillar has about 175 dealerships word wide operating in 200 countries.[48]

This doses not include all the distributors for other brands that Caterpillar now owns. The recently acquired Bucyrus has yet to be integrated & it was reported at the time of the deal that the largest mining products would be handled by a separate division, but some of the small products merged within the main cat dealer network.[49]
