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.
