It was revised in 2002, and part of this revision included replacing the term “safe working load” with “rated capacity”. “The term ‘safe working load’ has been changed to ‘rated capacity’ and other uses of the word ‘safe’ have been avoided due to the legal significance placed on the word.”
Can you exceed SWL? Yes. Devices fitted to machines, such as cranes, which cut-out hoisting, derricking or trolleying motions, eg when the SWL is exceeded, should be regarded as part of the lifting equipment and be included in the thorough examination. This applies also to any radius/load indicator fitted to lifting equipment.
