Contrx gantry cranes are available in fixed and telescoping standard designs, with capacities from 1 to 20 ton. Custom and motorized travel designs are also available on request. Motorized designs for large capacities only. Goliath / Gantry Cranes are self propelled cranes running on rails installed at ground level. Such cranes are used at -

Construction sites
Ports and harbors
Workshops where existing columns cannot bear the wheel loads of a bridge crane
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 loadshare to be shifted from points outside the crane span as in the case of an overhang on either side of the rails

In workshops where part utilization of shop bay is required (as in a tool room attached to a press shop), a Semi-Goliath/ Gantry Crane is used. In such a configuration one end-carriage of the crane will travel on the regular gantry rail while the opposite end-carriage will travel on a rail mounted typically on the ground.
