In a broad sense, elevators, overhead cranes, winches, stabilizers, cranes, hoists, etc. can all be called hoists. Hoists generally refer to large-scale mechanical equipment with high power and strong lifting capacity. The transportation process is completed by dragging the flexible wire rope and the transported goods up and down by power machinery. Wire rope is an indispensable and important part of lifting machinery. The main varieties are phosphate coated wire rope, galvanized wire rope, stainless steel wire rope, smooth wire rope, etc.

[0007] Preferably, the six arcuate sprocket discs are arranged in a circle, and large bolts penetrate the outside of two discs, and a large nut is threadedly connected to the outside of the large bolts on one side of one disc.
[0008] Preferably, the number of the large bolts is six, and the large bolts pass through the inside of the circular hole.
