Abstract
The bucket lift of a distribution crane is controlled by a device which includes a single drum hoist. A second single drum hoist is used to shut the bucket by means of two cables routed on the two pulleys located on the tip of the boom. The movement of the distribution carrier along the boom of the crane is controlled by a distribution hoist which includes two drums that are bound in rotation with the two drums of the lifting and shutting, through an epicyclic gear set. As the dsitribution hoist is activated, the bucket moves horizontally, thus reducing the amount of strain put on the distribution hoist, as well as the cable wear.
