ROPE INSPECTION SUMMARY
Any wire rope that has broken wires, deformed strands, variations in diameter, or any
change from its normal appearance, must be considered for e replacement. It is always
better to replace a rope when there is any doubt concerning its condition or its ability to
perform the required task. The cost of wire rope replacement is quite insignificant when
considered in terms of human injuries, the cost of down time, or the cost of replacing
broken structures.
Wire rope inspection includes examination of basic items such as:
1. Rope diameter reduction
2. Rope lay
3. External wear
4. Internal wear
5. Peening
6. Scrubbing
7. Corrosion
