WIRE ROPE. Visually inspect all wire ropes. Rope conditions requiring evaluation of safety and
consideration for replacement are as follows:
1.
Corrosion
2
More than one broken wire in any one strand.
3
More than one broken wire near attach fitting.
4.
Excessive wear and/or broken wires in rope sections under sheaves where rope travel is limited.
5.
Evidence of noticeable reduction in original rope diameter after allowance for normal stretch and
diameter reduction of a newly rigged rope.
6.
Excessive abrasion, scrubbing and peening of outside wires; pitting, bird-caging (deformation), or
other damage resulting in physical changes to the rope structure.
7.
Cracked, bent, worn, or improperly installed end connections (wedge socket, turnbuckles, etc.).
Sheaves, guards, guides, drums, flanges, etc., and any other surfaces that come in contact with the rope
should be inspected for any condition that could cause possible damage to the rope.
HOOK BLOCK. Visually inspect for nicks, gouges, cracks, and evidence of any other damage. Replace
a hook containing cracks or showing evidence of excessive deformation of the hook opening (including
twist). Be sure safety latch is free and aligned.
