- There should be lubrication in a wire rope and periodically change it for good strength of rope.
- If a wire rope is new or unused always, apply minimum breaking strength.
- It should be considered by a design factor for minimum or normal breaking strength if it reduced and it is not similar for all machines as well as work force so determine from design factor for your actual use strength.

- It should be proper testing for when to stop a rope.
- A qualified person should test for broken wires.
- They should examine corrosion.
When to change electric wire?
- If more than three wires broken in a pendant standing ropes in one lay length
- If is damaged by heat on a metal part.
- Wound on drums and passed through sheaves six or more broken wire on one lay length.
- If Support is missing in diameter, workload, or sizes.
