Single Girder Overhead Crane

The Single Girder Overhead Crane is made of a main beam supported at each end by headstocks that conduct the Bridge's translation action. The hoisting device; lifting and steering mechanism; operates on the main beam. It should also be noted that many hoisting devices may operate on the same overhead crane, either concurrently with the main device or as an auxiliary function.

Double Girder Overhead Crane

The Double Girder Overhead Crane consists of two main beams supported at the ends by the headstocks that perform the translation movement of the Bridge. The differential gear; lifting and steering mechanism; works on the two main beams. It should also be noted that more than one differential gear may operate on the same overhead crane, working simultaneously with the main gear, or performing an auxiliary function.
