Proof Load Testing of Lifting Equipment
Proof load testing is designed to ensure that items of lifting equipment can perform to the required standard in accordance with manufacturer’s guidance, by giving it a full strength test. Proof load tests are often needed in addition to the statutory requirements, e.g. LOLER regulations.
When is Proof Load Testing Required?
A proof load test is required on installation of any lifting equipment before the item is brought into service.
There may be other times in the equipment’s life where a proof test is required, e.g.
- following a weld repair to a structural member
- after a complete overhaul
- following an incident
- periodic testing may be specified in some British standards, e.g. BS7121, applicable to lorry loader cranes
