Wire Rope Sling

1. In case any of the following circumstances, the wire rope slings shall be stopped from use and be repaired, replaced or scrapped.

2. Broken wires exceed 5% of the total number in a continue length of 6 times wire rope diameter.

3. Visible Broken wire over 3 numbers.

4. Broken wires appear in the loop end or near to the press sleeves or splicing area.

5. Heavy wear wire rope, the measured diameter is less than 90% of the nominal diameter of the wire rope china lifting sling.

6. Bad corrosion with rough surface and measured diameter is less than 93% of the nominal diameter.

7. Wire rope has distortion, crushing, core damage and wire rope flattening caused by knotting, twisting and extrusion exceed 20% of the original nominal diameter

8. Thermal damage of steel wire rope: due to the hot melting of steel wire rope and molten metal scalding due to the charged thermal arc, or due to its strength reduction due to long-term exposure to high temperature environment.

9. The connector is severely squeezed, worn, the metal sleeve is damaged (such as crack, serious deformation, corrosion) or the diameter is reduced to 95% of the original nominal diameter.

10. The metal sleeve or plug-in part fixedly connected to the rope end slides out.

The maximum temperature that the wire rope sling can withstand is 100℃. Generally, when the temperature exceeds 60℃, the loss of grease of the wire rope will be accelerated and the service life of the wire rope sling will be reduced. If there is ambient temperature when use the wire rope sling, the operator will be in dangerous.

Wire rope slings should be stored in a clean, well-ventilated, dry, dust-free and sheltered place. If it cannot be stored indoors, the wire rope slings should be covered with a waterproof material to prevent moisture from rusting.
