The end of the hauling rope is connected with a component of a lift car, a counterweight or a machine room bearing beam. Taper sleeve type, self-locking wedge type, rope clamp type and other types. Of which the taper sleeve type is the most commonly used; the self-locking wedge type is less in use; the rope clip is used more, and is generally used as a sundry elevator; other types have structures such as a splicing rope head and a sleeve fixing screw head. The end of the main rope is treated by rope end, the shackle bar connected with the rope sleeve is communicated with the cage frame hole, the counterweight frame and other retainer rope hitch plates, and then the shackle bar is fastened by double nuts. Springs are typically incorporated at each shackle stem to ensure uniform tension in the hoist ropes. The mechanical strength of the combination of the hoisting rope and the rope head is at least 80% of the minimum breaking load of the hoisting rope.
In the traditional elevator rope head combination, a taper sleeve type rope head combination needs to arrange the end of a hoisting rope into the rope head combination and carry out permanent or semi-permanent locking; the structures of self-locking type, rope clamp type and the like need to fold the traction rope end in half and then put the traction rope end into a rope head combination. The bending radius of the hoisting rope at the folded part is generally 2-4 times of the nominal diameter of the hoisting rope, and after the hoisting rope is bent, the hoisting rope can be repeatedly used, particularly after the hoistway construction elevator needs to be lifted along with a temporary machine room, the bent hoisting rope needs to be used as a suspension hoisting rope, so that the hoisting rope has a great influence. Meanwhile, the rope head installation mode brings great inconvenience to multiple lifting operations of the temporary machine room.
