Wire rope sling is a wire rope as raw material after processing, mainly used for lifting, traction, pulling and carrying. The steel wire rope has high strength, light weight, smooth, not easy to suddenly the whole root fracture characteristics, widely used in iron and steel, chemical industry, transport, ports and other industries.
Below we summarize some possible situation, one of the following circumstances should stop the use of wire rope sling.
1, irregular attention of wire rope damage distribution, in the six times the length of wire rope range, with to the twisted rope visible broken wire total can not exceed 5% of the total number of steel wire rope, interactive rope twisting visible broken wires in the total can not exceed 10% of the total number of steel wire rope.
2, knot, distortion, distortion, caused by the extrusion of steel wire rope core crush, damage, or wire rope rope diameter is 20% more than the original flat
3, due to the burning of the wire rope caused by the burning arc or prolonged exposure to high temperature environment caused by the decline in strength
4, the compression, wear and tear, metal casing damage or diameter reduced to 95% of the original diameter
5, the rope end is fixedly connected with the metal casing pipe or the splicing part is sliding out.
