Abstract (en)

[origin: WO2013176630A1] The invention refers to a forestry winch, which is suitable for attachment to a tractor and by which a transmission of power from a tractor cardan joint shaft to a winding drum is arranged in such manner, that the efficiency is improved and machine parts are exposed to lower stresses, while the transmission gear (1) is integrated within said winding drum (3) as such. The winch according to the invention is further characterized in that said transmission gear (1) is a two-step planetary gear consisting of a first planetary assembly (81) and a secondary planetary assembly (82), which are. both- mounted within the- same easing (9). The planetary gearing (8) is on the one hand via a clutch (5) connected with an input shaft (2), which is connectable with said tractor cardan shaft, and on the other hand with the possibility of transmission of torque also with said winding drum (3), by which said casing (9) is at least partially surrounded, so that said casing (9) of the transmission gear (1) and the winding drum are arranged co-axially to each other, and simultaneously the winding drum (3) is allowed to rotate relative to the casing (9)·
