OVERHEAD CRANES

DOUBLE BEAM OVERHEAD CRANES

The overhead cranes are composed of two main beams supported at the extremities by the translation supporting heads and the hoist device works on top of the two main beams. It should also be noted that more than one hoist can operate on the same crane, working simultaneously with the main device or performing an auxiliary function.

SINGLE BEAM OVERHEAD CRANES

The single beam overhead cranes are composed by a main beam supported at the extremities by the translation supporting heads and the hoist device works under the main beam. It should also be noted that more than one hoist device can be operated on the same crane, working simultaneously with the main device, or performing an auxiliary function.
