1. The steel wire rope shall be laid evenly, tightly and not loose, and the steel wire shall not be wavy under the condition of unfolding and no load.
2. In a steel wire rope, the steel wire joints shall be minimized, and butt welding, brazing or splicing shall be carried out according to the specified methods.
3. In the same wire rope, the structure and laying condition of the same layer of strand shall be the same, and the lay distance shall not be significantly different.
4. The core size of the wire rope shall be able to ensure that it has sufficient supporting function, so that the outer wrapped strand can be evenly twisted.
5. All rope strands are not allowed to be spliced.
6. There shall be no broken, staggered or bent steel wire in the steel wire rope. The steel wire surface shall also be free of defects such as depression, rust, flattening, collision, forgery or cutting damage.
7. The steel wire rope shall be evenly twisted, and there shall be no "lantern" shape on the steel wire rope
8. There shall be no broken, cut, staggered and inverted steel wires in the sealing steel wire rope
9. Each layer of steel wire in the sealing rope shall be tightly and uniformly attached to the inner layer of steel wire, the surface of the sealing rope shall be flat, and the special-shaped wire must form a continuous seal
10. The sub rope group of the flat rope shall be arranged alternately by left and right twisting. The sub rope shall be evenly twisted and the whole rope shall be evenly twisted
11. The sub rope of the flat rope must be tightly stitched without looseness. The stitched strand wire on the side of the rope shall be close to the wire rope and shall not protrude.
