Between the three points formed by the adjacent clamping plate 704 and the trapezoidal clamping table 706 and the toothed disc 703, and the limiting rope 901 inside the mounting seat 8, the surface steel wire rope 5 under the hoist 6 continues to move quickly, realizing the anti-falling effect of the hoist in the crane, improving the safety guarantee in the hoisting process. When hoisting needs to be moved constantly, the weight of the hoist 6 needs to be lifted first, and during the lifting process, the limiting rope 901 is constantly wound under the action of the binding disc 902, and when the top is lifted, the limiting rope 901 on the surface of the binding disc 902 contacts the piston plate 905, extruding the resin in the storage cylinder 904 into the sleeve 903. The resin gradually flows down and combines with the slotted steel wire rope 5 with moisture, and the resin solidifies after mixing with white water, thereby strengthening the strength of the steel wire rope 5 at the end, and the limiting rope 901 on both sides of the bottom of the mounting seat 8 is tensioned in a triangular shape, avoiding continuous shaking during lifting and affecting the overall hoisting effect.
