Development and Application of Lever Type Anti Jump Device for European Winch Crane

In view of the problem that the steel wire rope of the hoisting mechanism of the light European double beam winch crane under 50 t is easy to jump, a lever type anti jump device is developed and manufactured. The device can assist the drum rope groove to control the wire rope to be arranged in order and wound on the rope groove to avoid groove skipping. At the same time, it also enables the crane to have the function of rope groove skipping detection, so as to avoid accidents caused by rope groove skipping and bring potential safety hazards to production.
