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 truck s 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.
