Wire Ropes, Chains, and Ropes

  • Wire ropes, chains, ropes, and other rigging equipment must be inspected prior to use and as necessary during use to ensure their safety.
  • Defective gear must be removed from service immediately
  • Job or shop hooks and links or makeshift fasteners formed from bolts, rods, or other such attachments must not be used.
  • When U-bolts are used for eye splices, the U-bolt must be applied so that the “U” section is in contact with the dead end of the rope.
  • When U-bolt wire rope clips are used to form eyes, the following table must be used to determine the number and spacing of clips.
