Komatsu is a Japanese company that manufactures construction, mining, and military equipment, industry machinery such as press machines, lasers, and thermoelectric modules.
Komatsu is the world's second largest manufacturer of Construction and Mining Equipment after Caterpillar. However, in certain geographic areas (Japan, China, Middle East), Komatsu has a larger market share than Caterpillar.[citation (source) needed]
Its headquarters is at 2-3-6, Akasaka, Minato-ku, Tokyo, Japan.
Its name was taken after the current city of Komatsu, Ishikawa at the company's foundation there in 1917. Its main plants are located in the city.
Komatsu makes the largest bulldozer in production in the world, the D575, the Italian company Umberto ACCO built a one-off machine of 1,300 hp (970 kW), weighing in at 183 ton, for a contract in Libya, which never took place.
History[]
Komatsu Iron Works was started by Takeuchi Mining Industry as a subsidiary to make industrial tools for the parent company. Komatsu eventually became large enough to sell to the public, and was spun off on 1921-05-13 as Komatsu Ltd.
Komatsu produced its first agricultural tractor prototype in 1931. Through the 1930s, Komatsu also produced military tractors for the Japanese military, as well as bulldozers, tanks and howitzers. After World War II, Komatsu added non-military bulldozers and forklifts to its line of equipment. Its growth as a company was aided by the strong demand for its bulldozer during Japan's post-war reconstruction in the 1950s. By 1957 they had advanced enough technologically that all of there models were also using Komatsu's own engines.
Komatsu began exporting its products in the 1960s, looking to counteract the postwar image of Japanese products as being cheap and poorly made, and entered the U.S. market in July 1967, taking on Caterpillar, the world's largest bulldozer maker, in its home market, under the leadership of President Yashinari Kawai. Komatsu did so under the rallying cry "Maru-C", translating into English as "encircle Caterpillar" (in the context of Go (board game) encircling an opponent results in capture of their territory).
Expansion overseas was a major focus in the 1970s, with Komatsu America Corporation being established in February 1970 in the United States. A year later, in January 1971, Komatsu Singapore Pte. Ltd. was established in Singapore. September 1974 saw the founding of Dina Komatsu Nacional S.A. de C.V., a joint venture with truck maker DINA S.A. in Mexico. April 1975 was the founding Komatsu do Brasil Ltda. in Brazil. This company produced the Komatsu D50A bulldozer, marking Komatsu's first offshore production of construction equipment. Komatsu Australia Pty., Ltd. in Australia was established in Feb. 1979.[1]
In the 1980s, Komatsu and International Harvester of the USA had a joint venture to produce compact tractors called KIMCO.
In 1982, PT Komatsu Indonesia was founded and began production began in 1983 in Indonesia. Two divisions in the USA were established for manufacturing in 1985, Komatsu America Manufacturing Corp. and Komatsu America Industries LLC. Komatsu Industries Europe GmbH was set up in 1986 in Germany.[1]
Komatsu and Dresser Industries established Komatsu Dresser to make mining tractors, construction equipment and related equipment in 1988[2] This 50-50 ownership lasted from September 1988 to August 1994, when Komatsu bought out Dresser's share.[2] Komatsu's mining products were consolidated under the name Komatsu Mining Systems in 1997. To prevent brand-name confusion during these corporate changes, the name "Haulpak" was used for the product line Komatsu began with Dresser. The name "Haulpak" dates back to 1957 when LeTourneau-Westinghouse introduced a range of rear dump trucks known as "Haulpaks". LeTourneau-Westinghouse equipment later became known simply as WABCO equipment in 1967. The name Haulpak was an industry term that eventually became applied to any type of rear dump truck. A detailed history of the development of the Haulpak can be found in Wabco Australia.[3]
In 1989, Komatsu bought a share of Hanomag AG and since 2002 Komatsu Hanomag GmbH has been a 100% subsidiary of the global company.
During the 1990s Komatsu had a joint venture in Europe with Moxy were Komatsu designed ADTs were built under license for the European market by Moxy. (in 2008 Moxy was taken over by Doosan of Korea).
Fai S.p.A. of Italy was invested in during 1991. As Komatsu's equity increased, the company was renamed in 1985 to FKI Fai Komatsu Industries S.p.A., which was then renamed in 2000 to Komatsu Utility Europe S.p.A. when Komatsu assumed 100% ownership.[1]
Komatsu owns the former Demag range of Mining Machines, which have been upgrades but are basically the same, with the PC3000 being the old Demag H185, of which over 200 have been built under both brands/model nos.
In 1993, two joint ventures were formed with Cummins; Komatsu Cummins Engine Corporation (KCEC) to manufacture Cummins engines in Japan, and the Cummins Komatsu Engine Corporation (CKEC) to manufacture Komatsu engines in the USA. Another joint venture was set up in 1997 to manufacture industrial engines in Japan.[1]
Additional overseas expansion, primarily in Asia, was accomplished in the 1990s. Komatsu Saigon Co., Ltd. in Vietnam in 1995; Komatsu Changlin Construction Machinery Co., Ltd. (renamed Komatsu(Changzhou) Construction Machinery Corporation in November 2000) in Changzhou, China in 1995; Komatsu Shantui Construction Machinery Co., Ltd. in 1995; Bangkok Komatsu Co., Ltd. in Thailand; Komatsu (Shanghai) Ltd. in 1996 in Shanghai, China; Industrial Power Alliance Ltd. in Japan, a joint venture with Cummins, in 1998; L&T-Komatsu Limited in India in 1998 (shares sold in 2013); and Komatsu Brasil International Ltda. in [{Brazil]] in 1998.[1]
The 2000s saw Komatsu working with The Linde Group of Germany for sales and manufacturing of lift trucks. In 2001, Komatsu established GALEO as a new brand of new-generation construction equipment for worldwide distribution. 2002, Komatsu Italy S.p.A' was established. In 2004, Komatsu Forest AB was established to purchase Sweden's Partek Forest AB, formerly Valtra and Valmet, a manufacturer of forest machinery. Also in 2004, founded Komatsu Zenoah (Shandong) Machine Co.,Ltd in China, (renamed Komatsu Utility Machine Co., Ltd. in 2007), to manufacture mini excavators and hydraulic equipment, as well as founding Komatsu Power Generation Systems (Shanghai) Ltd. to manufacture power generators. Komatsu Forklift Manufacturing (China) Co., Ltd was also founded in 2004 in China to produce forklifts.[1]
Komatsu moved into Russia in 2008 with Komatsu Manufacturing Rus, LLC being founded, and production began in 2010.[1]

The factory is a full production line fabricating pre-cut plate & sheet steel to make the major elements from scratch, like booms and main frames. The factory is a former Caterpillar plant, that was used to benefit from the North East's Engineering and fabrication skills base from the ship building & heavy industries following there decline in the 1970s. Caterpillar still have a plant near by at Peterlee that builds ADTs.
Engines come from the Cummins Engine factory at Darlington down the road, on a JIT (Just In Time) basis.
