10. When a wire rope has been removed from service because it is no longer suitable for use, IT MUST
NOT BE RE-USED ON ANOTHER APPLICATION.
11. Every wire rope user should be aware of the fact that each type of fitting attached to a wire rope has a
specific efficiency rating which can reduce the working load of the rope assembly or rope system, and
this must be given due consideration is determining the capacity of a wire rope system.
12. Some conditions that can lead to problems in a wire rope system include:
• Sheaves that are too small, worn or corrugated cause damage to a wire rope.
• Broken wires mean a loss of strength.
• Kinks permanently damage a wire rope and must be avoided.
• Wire ropes are damaged by knots, and wire ropes with knots must never be used.
• Environmental factors such as corrosive conditions and heat can damage a wire rope.
• Lack of lubrication can significantly shorten the useful service life of a wire rope.
• Contact with electrical wires and the resulting arcing will damage a wire rope.
Recommended Lubrication Product:
A high-grade penetrating lubricant for wire rope, chain and cable that contain a petroleum solvent that carry
the lubricant into the core of the wire rope, then evaporates, leaving behind a heavy lubricating film to
protect and lubricate each strand. A penetrating lubricant is essential in any lubrication program as most
wire rope fails from the inside out.
Check and lubricate all guide rollers, sheaves and hardware that are in operational contact are visually
checked for wear and lubrication
HOW OFTEN TO INSPECT
• Lifting cables should be visually inspected at least once each day when in use, as suggested by
American Petroleum Institute (API) RP54 guidelines.
• Any lifting cables that have met the criteria for removal must be immediately replaced.
WHEN TO REPLACE LIFTING CABLES DUE TO BROKEN WIRES
• Lifting cables should be removed from service when you see six randomly distributed broken wires
within any one lay length, or three broken wires in one strand within one lay length.
OTHER REASONS TO REPLACE
WIRE ROPE
• Corrosion that pits the wires and/or
connectors.
• Evidence of kinking, crushing, cutting,
bird-caging or a popped core.
• Wear that exceeds 10% of a wire’s
original diameter.
• Evidence of heat damage.
