How is Safe Working Load (SWL) defined?

Safe Working Load is the maximum load a lifting device is considered safe to lift in normal use, calculated as the breaking strength divided by the safety factor. The breaking strength is the force at which the equipment would fail, and the safety factor accounts for uncertainties like dynamic forces, wear, and misuse. By dividing the breaking strength by the safety factor, you establish a conservative limit that helps prevent failure during real-world operation. For example, with a breaking strength of 50,000 N and a safety factor of 5, the SWL would be 10,000 N. This limit is not the actual weight being lifted, nor simply the average rated load, and it’s not obtained by multiplying by the safety factor.
