For anyone who ever stood in awe of a three-story-high dump truck or marveled at the engineering revolution propelling mechanical vehicles into the robotic age, Ultra Haulers presents the past, present, and future of the worlds greatest haul trucks. From early rigid trucks and articulated dump trucks to tire technology and scraper tractors, Ultra Haulers details the innovations, evolutions, and revolutions in large-scale earthmoving equipment. Author Mike Woof, former editor-in-chief of World Mining Equipment magazine and current international editor for E&MJ and Coal Age, is a leading authority on mining equipment, including the largest, most sophisticated factory-made equipment produced. The book incorporates original analysis, primary data, and firsthand commentary, putting an ear to the ground and a finger to the pulse of this dynamic and exciting field. Both knowledgeable hobbyists and industry veterans will enjoy Woofs sweeping overview, which is beholden to no one manufacturer, no one type of machine, and no one era, but to the entire field. With expert, prescient commentary, Woofs understanding of these machines and enthusiasm for the engineering triumphs they represent comes through on every page.
