Sep,1988 Established Komatsu Dresser Company in the United States. Komatsu and Dresser Industries established Komatsu Dresser to make mining tractors and related equipment.[5] This 50-50 ownership lasted from September 1988 to August 1994, when Komatsu bought out Dresser's share.[5] 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 Construction
