7.5.8 SWL

For lifting applications, under normal operating conditions, i.e. where there are no hazardous conditions the SWL will be the same as the rated capacity. The rated capacity of the winch and wire rope should not be more than 20% of the failure load, i.e. there should be a minimum factor of safety of 5:1. For certain terminal fittings this factor may be 4:1.

For people carrying applications, the SWL should not exceed 50% of the rated capacity, i.e. the factor of safety should be increased to a minimum of 10:1. Additional precautions are however required.
