Mobile Gantry Cranes

Double beam gantry cranes

The gantry cranes are composed of two main beams based over four legs, connected to the end carriages that execute the translation movement of the gantry crane. The hoist; lifting and direction movement; works on top of the two main beams. It should also be noted that more than one hoist can work on the same gantry crane, working simultaneously with the main hoist or performing an auxiliary function.

Single beam gantry cranes

The gantry cranes are composed of one main beam, which has two or four legs, connected at their bottom to the end carriages that execute the translation movement of the gantry crane.  The hoist device works under the main beam. It should also be noted that more than one hoist can work on the same gantry crane, working simultaneously with the main hoist or performing an auxiliary function.
