Assessing the condition of the hoist rope

If in doubt about damage assessment, always consult an official inspector.
To assess the condition of the rope, you must be familiar with the following:
– The type of rope (regular lay)
– 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 regular lay rope (1), the wires run more or
less in the longitudinal direction of the rope.
You get the number of load-bearing outer
wires (1), by counting the number of outer
strands of the rope and multiplying by 7.
