Forestry winch comprising a winding drum, a brake, a clutch, a chain wheel, a lamellar chain, a driving chain wheel and a hydraulic assembly for controlling said winding drum by means of said brake and clutch in said forestry winch, wherein the hydraulic assembly is a hydraulically controlled displacing assembly, the hydraulic assembly comprising a shaft, which is embedded within a casing of said winch and on which said essentially cylindrical winding drum is mounted, which is suitable for coiling and decoiling of each towing cable and is freely rotatable but also immovable in the axial direction of said shaft, and which is moreover on its first front side furnished with a brake disc with a smooth cylindrical friction surface, which is suitable for cooperation with a belt of each corresponding belt brake, while on the opposite front side of said winding drum said chain wheel is mounted on said shaft also immovably in the axial direction of said shaft and is via said lamellar chain driven by means of said driving chain wheel, which is mounted in appropriate area within said casing of the winch and is driven by means of a cardan shaft, by which the forestry winch may be coupled with the engine of a tractor, to which the forestry winch is coupled during the use in such a manner that its casing is attachable to the tractor by means of a common three-point coupling mechanism, wherein said clutch is a multiple-plate clutch and is mounted on said shaft, so that its friction discs are by means of said hydraulically controlled displacing assembly displaceable along the shaft and are also adapted to be pressed against said winding drum, so that upon activation of the clutch and deactivation of the brake the torque is transmitted from said chain wheel onto the winding drum, while upon deactivation of the clutch and activation of the brake despite to continued rotation of said chain wheel transmission of the torque onto said winding drum is interrupted, characterized in that said clutch together with its friction discs is located on the same side of the winding drum as the brake disc, and said friction discs of the clutch are by means of a hydraulic displacing assembly displaceable in a direction along the shaft, namely towards said front side of the winding drum and in that said hydraulic displacing assembly is embedded within a bearing assembly of said forestry winch, which said bearing assembly is also foreseen for bearing of said shaft within the casing of the forestry winch, so that a casing of bearings (71, 72) of the shaft on the side of brake and clutch represents a stationary unit of said displacing assembly, along which a movable unit of said displacing assembly is by means of pressure of the hydraulic media displaceable in said axial direction towards said friction discs of the clutch. said clutch is a multiple-plate clutch and is mounted on said shaft, so that its friction discs are by means of said hydraulically controlled displacing assembly displaceable along the shaft and are also adapted to be pressed against said winding drum, so that upon activation of the clutch and deactivation of the brake the torque is transmitted from said chain wheel onto the winding drum, while upon deactivation of the clutch and activation of the brake despite to continued rotation of said chain wheel transmission of the torque onto said winding drum is interrupted, characterized in that said clutch together with its friction discs is located on the same side of the winding drum as the brake disc, and said friction discs of the clutch are by means of a hydraulic displacing assembly displaceable in a direction along the shaft, namely towards said front side of the winding drum and in that said hydraulic displacing assembly is embedded within a bearing assembly of said forestry winch, which said bearing assembly is also foreseen for bearing of said shaft within the casing of the forestry winch, so that a casing of bearings (71, 72) of the shaft on the side of brake and clutch represents a stationary unit of said displacing assembly, along which a movable unit of said displacing assembly is by means of pressure of the hydraulic media displaceable in said axial direction towards said friction discs of the clutch.
