8.12.4 Assessing the condition of the hoist rope
H
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 (
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.
H
If there are multiple layers of strands, only the outer layer is counted.
