Assessing the condition of the hoist rope

If in doubt about damage assessment, always consult an approved inspector.
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 strand,
– 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.
