Abstract (en)
[origin: EP1247778A2] The lifting winch has a rotatably mounted drum (12) and a drive (16) by which the drum is rotated for winding a cable (11) onto it and off it. A control unit and measurement unit continuously determine the momentary tensile force on the cable. When the tensile force falls below a predetermined residual tensile force the power of the drive is corresponding reduced by the control unit and adjusted, whereby the tensile force is kept below the residual tensile force by regulation. An Independent claim is included for a procedure for the operation of a lifting winch.
