Inspecting the wire rope

 

*   Inspect the entire wire rope for damage. The damage shown here or any similar damage should not be detectable on the wire rope.

Examples of damage:

The joining of the wire rope has opened. The inner strands of the wire rope are visible.

 

Loops have formed in the wire rope.

 

There is a kink in the wire rope. This can result, for example, from violent external forces being applied to the wire rope.

 

The wire rope is flattened at one point. This can result, for example, from the wire rope being pinched.

 

A bird cage has formed in the wire rope. This can result, for example, from violent untwisting of the wire rope.

 

The wire rope has a corkscrew-type deformation.

 

 

*   Check the entire wire rope for broken wires. The wire rope must not exhibit more broken wires in a length of 6 times its diameter or 30 times its diameter than is specified for these lengths on the ABUS manufacturer's certificate for wire ropes in the test log book.

Examples of broken wires:

 

Multiple broken wires. Broken wires are signs of normal wear of the wire rope. They occur when the wire rope is bent on the reels under load.

 

Broken wire with protruding wire end.

 

 

*   If damage such as that pictured or similar damage is detected on the wire rope, replace the wire rope with a new one.

*   If the wire rope has broken wires, but not exceeding the permissible number, shorten the test interval until the next regular inspection.

*   If the wire rope has more broken wires than permitted, replace the wire rope with a new one.
