Abstract (en)
[origin: EP1103511A2] The winch operation monitoring method determines the cable force, the load variations, the dynamic response and/or the residual working life of the winch (1), with detection of the torque of the winch drive (2) and the position of a lever arm of the winch cable (4), for calculating the cable force. The collective loading is determined from the time characteristic of the cable loading, for calculation of the residual working life. An Independent claim for a monitoring device for the operation of a lifting winch is also included.
