PREVENTION APPARATUS FROM CONFUSED STEEL WIRE ROPE WINDING MOVABLE WINCH

摘要

This prevents wire ropes from winding around when the crane is over-wound.;The winding position detection sensor 10 is mounted on the sheave bracket 4 fixed to the tip of the boom 1, and the weight is passed through the wire 13 to the rod 12 protruding from the winding position detection sensor 10. (14) is hanging. When the hook 6 is rolled up and the distance between the sieve bracket 4 and the hook becomes shorter than the predetermined length b, the weight 14 abuts on the hook 6, and the wire 13 is loosened and wound up. The detection sensor 10 is switched off. The signal is received by the controller and the hydraulic pressure or speed of the winch for winding the hook 6 is reduced, the tension and speed of the wire rope 5 are reduced, and the wire rope is fed into the wire rope wound on the winch drum. Prevents the creation of random power.
