Gantry / Goliath Cranes

Gantry / Goliath Cranes are adapted to applications where overhead runways would be very long, costly to erect, and difficult to maintain in alignment. Where the installation is only temporary, a gantry crane can be moved to a new location with less trouble or expenses than an overhead crane and its runway. Also it is comparatively easy and inexpensive to extend the length of the runway and thus increase the working area of the crane. Most gantry crane installations are outdoors. The initial cost of a gantry crane, which may be double that of an overhead crane, must be equated against the additional cost of an overhead runway.

Goliath / Gantry Cranes are self-propelled cranes running on rails installed at ground level.
Applictions of these type of cranes are -

  • Construction sites
  • Stockyards, Ports and harbors
  • Marble and granite industry
  • Workshops where existing columns cannot bear the wheel loads of a single or double girder bridged crane
  • Workshops 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 the 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
