<p>The winding device with differential band break of a forestry winch with improved differential band brake (10) features a hydraulic unit (103) made as a single-direction pulling hydraulic cylinder. Inside the hydraulic cylinder (1032) there is a release spring (1034) located between the bottom of the hydraulic cylinder (1032) and the piston rod (1031). On the rod (1031) there is a triggering spring (1033) located between the hydraulic cylinder (1032) and the differential lever (102). The triggering spring (1033) as well as release spring (1034) are implemented as pressure springs. The differential brake (10) is implemented inside the enclosure (2).</p> |
