Wire rope use and scrapping standards

　　1. The wire rope is mechanically damaged due to the load on the sharp projections.

　　2. Local wear due to friction of the support structure. The wire rope vibrates between the sky wheel and the reel.

　　3. Narrow wear can cause fatigue breakage, which can be caused by wire ropes working in oversized rope grooves or working in too small support tanks.

　　4. The wire rope is severely worn and the main core of the fiber protrudes. Should stop using, replace the new wire rope

　　5. Severe wear of the same-twisted wire rope due to friction between the intersections of the multi-layer wound wire ropes.

　　6. The steel wire rope is immersed in the chemically treated water and the steel wire rope will be damaged. Therefore, the wire rope should be placed in moisture-proof and dry.

　　Storage.

　　7. There is almost no sign of damage on the exterior, but the internal corrosion is rusted, and the gap between the strands completely disappears.

　　8. Typical broken wire caused by bending fatigue of wire rope. This type occurs mostly in the type of point contact wire rope, so it is recommended to use a wire contact wire rope.

　　9. The hungry wire between the strands or the cord is significantly different from the strand "top" broken due to lack of rope support.

　　10. Disconnected under the action of high stress (the main structure of the independent structural steel wire rope), pay attention to the biting of the outer strand steel wire.

　　11. The core is protruding and the wire rope should be replaced with a larger wire rope due to the distortion caused by the sudden load.

　　12. Typical conditions of local wear and deformation in previously knotted areas.

　　13. Multi-strand wire ropes have a "birdcage" shape, which can be seen in the anchoring end of a multi-rope crane due to distortion imbalance.

　　14. Protruding due to sudden load (independent structural wire rope main core).

　　15. Significant wear and severe internal rust. In this case, high tensile forces, friction and corrosive environments coexist.
