Scrap Standard For Wire Rope

Rope scrap standards are as follows:

1. For the cross-wound wire rope, the number of broken wires within a lay distance (refers to the axial distance of any wire rope strand around) shall be 10% of the total number of wires of the rope.

2, lifting hot metal or dangerous goods of the wire rope, the number of scrap broken wire to take half of the general crane, namely 5%.

3, the surface layer of steel wire rope corrosion or wear up to 40% of the surface of the original wire diameter.

4, the wire rope has obvious internal corrosion.

5. The diameter of wire rope can be reduced by 7%.

6, the steel wire rope and aluminum alloy joint parts crack or slip deformation; The insertion part of the pluggable wire rope is seriously pulled out. The casting steel wire rope anchorage and steel wire rope displacement, the phenomenon of pumping.

7, the surface of the wire rope wear or corrosion, and a certain number of broken wire.

8. The whole strand is broken or burned out.

9, local outer wire rope elongation is "cage" shape or wire rope fiber core diameter increase is serious.

10, the rope torsion, dead Angle, hard bending, plastic deformation, hemp core out and other serious deformation.
