The end of the main rope is processed as a rope end, a shackle rod connected with the rope sleeve is communicated with a car frame hole, a counterweight frame and other stop piece rope end plates, and then is fastened by double nuts. Springs are typically inserted at each shackle stem to ensure uniform tension in the hoisting ropes. The mechanical strength of the hoisting rope in combination with the rope head should be at least 80% of the minimum breaking load of the hoisting rope.
In the traditional elevator rope end combination, the taper sleeve type rope end combination needs to be provided with a traction rope end in the rope end combination and is locked permanently or semi-permanently; the self-locking type and rope clamping type structures are all required to fold the traction rope end in half and then put into the rope end combination. The bending radius of the hoisting rope at the folded position is generally 2-4 times of the nominal diameter of the hoisting rope, and after the hoisting rope is bent, the hoisting rope is repeatedly used, and particularly after the hoistway construction lifter is lifted along with a temporary machine room, the bent hoisting rope is required to be used as a suspension hoisting rope. Meanwhile, the rope end installation mode brings great inconvenience to the repeated lifting operation of the temporary machine room.
