Abstract (en)
[origin: EP0316757A1] In order to reduce the dynamic stresses associated with the lifting of a moving load in a lifting device, the drive motor of the drive arrangement for the rope winch and/or the rotating mechanism of the lifting device is connected to a differential gearing (2), one shaft of which is in operative connection with the rope winch (3) or via a pinion with the rotating mechanism of the lifting device. The third shaft (4) is connected to a holding device. The holding device is formed by a rope pulley (5) which has at least one rope (6) wrapped around it, and one end of the rope is connected to a damping means (7) whose damping behaviour is conveniently adjustable.
