Abstract
A winch has a supporting frame with a first wall and a second wall. The winch also has a drum interposed between the first and second walls and is supported by them so as to rotate about its longitudinal axis which is transverse to the walls. The winch also has a flexible element for moving a load being wound around the drum. The winch also has a drive structure associated with the first wall and with a transmission structure for rotationally actuating the drum. The winch may also have a reaction element which is associated with the second wall, which supports the drum so as to rotate and which is associated with the transmission structure in order to support them.
