    According to the invention, it is provided that the upper guide roller 3 of the forestry winds around the geometric axis 320 of the pulley 32 includes a swinging leg 35, at the free end 351 of which the steering sleeve 33 is provided for the steering of the traction cables 2, wherein said leg 35 is provided in the region around its pivot point, which overlaps with the geometric axis 320 of the pulley 32, with the skirt 352 on which the first attachment point 341 of the gas damper 34 is present, the second attachment point 342 on the housing 31 the upper guide roller 3 is arranged, in such a way that in the starting position of said leg 35, the connecting line 340 between the two attachment points 341, 342 intersects the pivot point of the leg 35, namely the geometric axis 320 of the pulley 32nd
    The term gas damper 34 means a device consisting of a piston rod 34 'and a cylinder 34 ", in which there is compressed gas, or a mixture of gases, for. For example, air. Under load, the piston rod 34 'moves into the interior of the cylinder 34 ", and after its discharge, it returns to its original position.
    At the free end 351 of said leg 35, a supporting rolling element 36 is arranged in the immediate vicinity of said steering opening 33, which is adapted for the cooperation with the traction cable 2. The rolling element 36 is preferably designed as a roller. Thanks to the aforementioned rolling element 36, the traction cable 2 is supported in the region of the aforementioned steering bushing 33, so that the friction between the cable 2 and the steering bushing 33 is minimized.
    In the preferred embodiment of the forestry winch according to the invention, the mentioned leg 35 is fork-shaped with the steering sleeve 33 and extends on the two sides 31 ', 31 "of the housing 31; on each side 31 ', 31 "of the housing 31 is a respective enclosure 352 with the first attachment point 341 of the respective associated gas damper 34. Accordingly, the winch is provided in the upper deflection roller 3 with two gas dampers 34, each on its side 31 ', 31 "of the housing 31 of the upper guide roller 3 is arranged and each by itself in the associated attachment points 341, 342 is attached.
