Haulpak was a very successful line of off-highway mining trucks. The name was used from 1953 until around 1999; the line continues under the Komatsu name. The name was adopted as Wabco Haulpak when R. G. LeTourneau's business was bought by Wabco, and the Haulpak name continued through Wabco's purchase by American Standard, the operation's purchase by Dresser Industries, the merger into Komatsu-Dresser, and for a time after Komatsu took complete ownership from Dresser.
History
The origins of the Haulpak line began with the purchase of R. G. LeTourneau's construction machinery business in 1953 by Westinghouse Air Brake Company. Wabco had traditionally been a manufacturer of railway air brake systems, but ventured into construction machinery with the purchase of LeRoi air tools and industrial drills in 1952. The subsequent purchase of R. G. LeTourneau's construction machinery line gave Wabco a comprehensive range of machinery including scrapers, rubber-tyred dozers and other attachments. Wabco subsequently added motor graders to their product line by purchasing J. D. Adams in 1955 and thereafter front end loaders, with the purchase of Scoopmobile.
