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
