Cab-down-style rough terrain cranes are designed for refineries, general contractors, heavy industrial plants and make great yard cranes. The lower profile of these cranes (ranging in capacities from 14 US tons up to 30 US tons) provide "pick and carry" capabilities in extremely tight working areas. These cranes also work well for Drill Rig Maintenance, Rail Road Maintenance, Hi-Rail Mounted, Mining Equipment Maintenance and Heavy Maintenance. The operator's cab is fixed and does not swing with the crane; hence the term "Neck Breaker" that is sometimes used to describe Down Cab RT's.
