8.9.4 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 strands
– The rope diameter (à Operating manual).
In a lang lay rope (1) the wires run 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.
H
If there are multiple layers of strands, only the outer layer is counted.
