Gorbel® Shop Crane™ Overhead Bridge Cranes are made of solid steel construction for long lasting durability and dependability. Two parallel steel tracks, or runways, guide a steel bridge over the work space. A non-binding trolley glides along the inside of the enclosed track on the bridge to give complete coverage within the frame of the 4-post structure. Allows a one-man operation to work with and position heavy loads safely and easily. Designed to maximize the amount of lift and headroom possible in standard garages. Used for vehicle restoration, maintenance on farm or golf course equipment or for maintaining a car, ATV, snowmobile or any motor driven vehicle. Available in 1000 and 2000 lb. load bearing units of various dimensions with usable width of 8, 10 and 12 feet.
