5.5.2 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 should be based on a minimum factor of safety of 5:1. This applies to the machine, the rope and the terminal fittings.

For pulling applications the manufacturer may permit a lower factor of safety (in the order of 3:1) to give a higher working capacity. Check in the manufacturer’s instructions for use.

For people-carrying applications, the factor of safety of the machine, rope and terminal fittings should be increased to a minimum of 10:1, i.e. the SWL should not exceed 50% of the rated capacity. Additional precautions are, however, required. (See 5.5.4 People carrying Applications - Special Requirements)
