If in doubt about damage assessment, always consult an official inspector.

– the type of rope (lang lay rope)
– the number of load-bearing wires in the outer strands
– the rope diameter (

In a lang lay rope (1) the wires ru
n at an angle
of approximately 45° to the longitudinal
direction of the rope.
The number of load-bearing outer wires (1)
is found by
counting the number of outer
strands of the rope and multiplying by 7.

If there are multiple layers of strands, only the outer layer is counted.
