A wire rope wears from the inside and the outside. Inspect the full length, especially where it runs over sheaves and at the end fixings.
Replace the rope when you find
- Broken wires above the limit of the standard (ISO 4309) for the rope type
- A reduction of diameter of about 10% or more
- Kinks, bird-caging, crushing or heat damage
- Heavy corrosion or a broken strand
Keep a record of every inspection — the trend tells you when the rope will need replacement.
