Cranes and lifting work put a lot of confidence in slings and rigging, which is why you should inspect them before every use. If a device does not pass inspection, take it out of service immediately and repair or replace it. Daily checks keep damaged equipment from being used, while annual inspections cover the overall health of the equipment.
What Do You Look for When Inspecting Rigging?
Check slings, wire rope, chain, and fittings for any sign of damage or wear.
- Missing or illegible sling identification, since each sling should be marked as inspected
- Melting or charring of any part of the sling
- Holes, tears, cuts, snags, or elongation of the sling
- Excessive abrasive wear
- Knots in any part of the sling
- Excessive pitting or corrosion, or cracked, distorted, or broken fittings
- Distortion of chain links
- Visible signs that cast doubt on the sling’s strength, such as loss of color that may indicate ultraviolet light damage
- Distortion, kinking, bird-caging, or other damage to the wire rope structure
- Wire rope with more than 10 percent of its wires broken within any length of eight diameters, which must not be used
