A hauling winch intended as accessory equipment for a forestry tractor or the like, comprising a body 13 and a cable drum 1 mounted so that it can rotate therein. The body is configured so as to be mounted on an extending and retracting boom 33 on the tractor or some other part of the tractor which can move by its own power arrangement. The cable drum is provided with releasable elements 16, which can lock it against rotation when tension is exerted in the cable 15 by retraction of the boom 33. Furthermore, the cable drum is provided with automatically operating elements, preferably in the form of a spring 10, for rotation of the drum and winding up of the loose cable thereon, when no traction force is exerted in the cable. <IMAGE> |
