Gantry and Goliath Cranes

Gantry and Goliath Cranes

Gantry cranes are same as the regular overhead cranes except that the bridge for carrying the trolley is rigidly supported on two or more legs running on fixed rails or other runway. These 'legs' eliminate supporting runway and columns and connect end trucks which run on a rail, either embedded in or laid on top of the floor. Workshops with low roof tie height that might restrict the height of lift of a regular bridge crane, Locations where bay lengths are excessive, Locations where bay lengths do not remain constant, Sites / projects where crane itself needs to be relocated from one place to another, Locations where loads are to be shifted from points outside the crane span as in the case of an overhang on either side of the rails.
