Haulpak and Lectra Haul: The World’s Greatest Off-Highway Earthmoving Trucks
In quarries and mines around the world, Haulpak and Lectra Haul off-highway haulers are legendary. The Haulpak truck line (launched in 1957) and the Lectra Haul diesel-electric drive truck (introduced in 1960) shaped the way all modern off-highway haulers are designed even to this day. The Haulpak name was carried by such companies as LeTourneau-Westinghouse/WABCO (Westinghouse Air Brake Company), Dresser, Komatsu-Dresser, and finally Komatsu. Lectra Haul was the trademark name for trucks built by Unit Rig, becoming part of Terex and sold to Bucyrus International. Each trucks designs were the templates for most future mining trucks. Construction Equipment author Eric Orlemann honors these off-highway haulers that carried these names, both past and present, with historic and modern photography, much of it never seen in published form before.
R G LETOURNEAU HEAVY EQUIPMENT,The Electric-Drive Era 1953-1970
Robert Gilmour LeTourneau is considered by many to be the dean of high-speed mobile earthmoving equipment. His designs of the 1920s, 30s, and 40s revolutionized the earthmoving industry. During the 1950s and 1960s, LeTourneau was able to develop and employ one of his greatest engineering design achievements - the electric drive wheel concept. This second volume of fantastic machine creations covers the time period from 1953 up until the sale of the company to Marathon in 1971. Standard production, specials, and experimental machines are shown in rare archival images, some being shown in print for the very first time, help showcase what made R. G. LeTourneau so revered in the heavy equipment industry.
