  • Method of operating a winch, and associated device
    Patent number: 5984277
    Abstract: The present invention relates to a method of operating a winch, in which a rope which is wound onto a driven reel is supplied to at least one capstan head and wound around said capstan head, with a capstan drive rotating the capstan head and producing a rope advance due to the rope friction existing between rope and capstan head. Moreover, the present invention relates to a corresponding device. As an improvement of the method and the device, the invention suggests a reel drive which is adjusted separately next to the capstan drive.
