Lifting gear should be tested by a ‘competent person’
- After installation
- After any major repairs
- Every 5 years
Lifting appliance are usually given a static test using a proof load or dynamometer (static test) , Proof load always exceeds the SWL (safe working load) by a given percentage or weight.
Code Of Safe Working Practices states that ‘a mass in excess of SWL should not be lifted unless’:
- A test is required
- The weight of the load is known and is the appropriate proof load
- The lift is a straight lift by a single appliance
- The lift is supervised by the competent person who would normally supervise a test and carry out a thorough examination
- The competent person specifies in writing that the lift is appropriate in weight and other respects to act as a test of the plant, and agrees to the detailed plan for the lift
- No person is exposed to danger.
Lifting plant must be ‘thoroughly examined’ by a competent person (Chief Officer)
- After testing
- At least once every 12 months
A ‘through examination’ means a detailed examination by a competent person, supplemented by stripping the gear down for inspection if this is judged necessary.
