Inspection of Wire Rope Slings, Hooks, Shackles and Winches Slings
Slings

6
Should be tested and tagged on a six monthly basis and marked with SWL and inspection date.
They shall be visually inspected by a competent person before all lifting operations.

Slings shall be rejected when there is:

1. Severe deformation - where strands are severely kinked or the core is protruding
2. Severe wear - wear of high points of the sling caused by dragging the sling across decks
contributes to early broken wires. A sling which has wires worn to half normal diameter on
high points should be replaced
3. Termination damage  Severe corrosion (be aware of the possibility of internal corrosion)
No SWL indicated or last inspection date/colour code missing.
Hooks and Shackles
1. Check that the SWL is adequate for the lifts
2. Use only hooks and shackles marked with the SWL
3. Check shackle and pin for excessive wear:
4. Make sure that the pin is free, but not loose in the tapped hole. Secure pins with wire to
prevent them vibrating free
5. Threads of the pin should be undamaged and without appreciable wear
6. Never replace the pin of a shackle with a bolt. Bolts may not be to the same standard and
could fail
7. Check shackle and pin for distortion
8. Check alignment of the pin holes; the untapped hole should not be too large.
