SEMI-GANTRY CRANES

DOUBLE BEAM SEMI-GANTRY CRANES

The double semi-gantry cranes are composed of two main beams, based a tone end over two legs, which are connected at their bottom to the translation head support and at the other end connected directly to the other translation head support and the hoist device works over the two main beams. It should also be noted that in the same semi-gantry can work more than a hoist, working simultaneously with the main deive, or performing an auxiliary function.

SINGLE BEAM SEMI-GANTRY CRANES

The single beam semi-gantry cranes are composed by a main beam, which is supported at one end over one or two legs, which are connected at their bottom to the translation head support and at the other end connected directly to the other translation head support and the hoist device works under the main beam. It should also be noted that in the same semi-gantry it can work more than one hoist, working simultaneously with the main device, or performing an auxiliary function.
