What are the standards for customized 7*19-1.2 wire rope scrapping?
1. If the radial wear or corrosion of the steel wire exceeds 40% of the original diameter, it should be scrapped. When it is less than 40%, the number of broken wires can be reduced and scrapped according to regulations.
2. Severe wear of the wire rope twisted in the same direction, caused by friction between the intersection points of the wire ropes wound in multiple layers.
3. If the whole strand is broken, it should be scrapped.
4. When the diameter of the customized 7*19-1.2 wire rope is reduced by 7% or more relative to the nominal diameter, even if no broken wire is found, the wire rope should be scrapped.
5. The exposed hemp core should be discarded.
6. The customized 7*19-1.2 wire rope has obvious corrosion and should be scrapped.
7. Part of the outer layer of steel wire elongated in a cage state should be scrapped
8. The wire rope press machine is mechanically damaged due to the load operation on the sharp protrusions.
9. Localized wear due to friction of the supporting structure. The customized 7*19-1.2 wire rope vibrates between the sky wheel and the drum.
10. Narrow wear can lead to fatigue fracture, which can be caused by working in too large a rope groove or working in a support groove casserole that is too small.
