When inspecting chain blocks, the following should be checked:

  • Chain blocks should be kept lubricated
  • Chain block brakes operation and their cleanliness from oil and grease (if applicable by the design)
  • Latches. They should be free from defects and move freely with proper fitment to the block
  • Wear of hooks and fittings
  • Damaged or distorted chain end anchor
  • Chain wear including bends, notches, elongations, twisting
  • Load slipping, jamming
  • Damaged covers
  • Illegible markings
  • Bent operating handles

If any defects have been found, they must be removed from service, kept separately and sent for examination/service/repair by an authorized party.

Slings should be inspected and removed from service if any of the below defects observed:

  • Missing or illegible sling identification
  • Acid or caustic burns
  • Melting or charring of any part of the sling
  • Holes, tears, cuts or snags
  • Broken or worn stitching in load bearing splices
  • Excessive abrasive wear
  • Knots in any part of the sling
  • Conditions that cause doubt as to continued use of a sling
  • Discoloration and brittle or stiff areas on any part of the sling
  • Pitted, corroded, cracked, bent, twisted, gouged or broken fittings
