Super-Duty Earthmovers

This colorful photohistory features the giant equipment used in the mining and excavation industries. A bucketload of magnificent color photography depicts giant rear- and bottom-dump trucks, track dozers, wheel dozers, wheel loaders, scrapers, graders and hydraulic excavators--all of which are shown at work and from dramatic angles that accentuate their gargantuan size. More than half of the 24 manufacturers represented are North American.
