  • Device for setting and automatic adjustment of the tractive force of a cable of an overhead winch for a ski slope preparation and maintenance machine
    Patent number: 6585232
    Abstract: Device for setting and automatic adjustment of the tractive forces of the cable of an overhead winch for a ski slope preparation and maintenance machine, comprises an adjustment control unit connected to a controllable winch drive; and a processing device connected to sensors and to the adjustment control unit. The sensors are pressure sensors which detect pressure applied to a selection valve with maximum value, the selection valve being connected between delivery ducts of hydraulic drives on the right-and left-hand sides of the ski slope preparation and maintenance machine in a first travel direction or a travel direction opposite thereto. The processing device includes an algorithm which calculates a nominal value based on the pressure taken by the pressure sensors and which controls the winch operation through the adjustment control unit.
