Massive earthmoving trucks are a critical link in the production of raw materials and the backbone of surface mining operations worldwide. The biggest trucks are wider than 30 feet and as tall as a two-story building, and can weigh as much as 260 full sized pick-up trucks when fully loaded. These are real bruisers, no doubt about it.
In quarries and mines around the world, Haulpak and Lectra Haul off-highway haulers are legendary and are some of the largest trucks in operation today. The Haulpak truck line launched in the late 1950s and the Lectra Haul diesel-electric drive truck introduced in the early 1960s, 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, which would become part of Terex, Bucyrus International, and now Caterpillar, Inc. Each truck's designs were the templates for most future mining hauler models in use around the world. Construction Equipment author Eric Orlemann honors these off-highway marvels that carried these names, both past and present, with historic and modern photography, much of it never seen in published form before.
