Assessing the condition of the hoist rope

If in doubt about damage assessment, always consult an approved inspec-
tor.
To assess the condition of the rope, you must be familiar with the following:
– the type of rope (lang lay rope)
– the number of load-bearing wires in the outer strands
– The rope diameter (
If there are multiple layers of strands, only the outer layer is counted.
à
Operating manual ).
In a lang lay rope (1) the wires run at an angle
of approximately 45° to the longitudinal direc-
tion 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.
