GANTRY / GOLIATH CRANES are running on rails installed at ground
level. Such cranes are used at –
Construction sites
Workshops where existing columns cannot bear the wheel loads of a bridge crane
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
Out door fabrication yards
Capacity : 3T to 30 T
In workshops where part utilization of shop bay is required (as in a tool room attached to a press shop), Semi-Goliath/Gantry Crane shall be 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 or at a lower elevation.
Gantry or semi gantry cranes can be either of the Single Girder type or Double Girder type.
