Lifting equipment, like hydraulic trailer cranes, fall under the Lifting Operations and Lifting Equipment Regulations, known as LOLER and Provision and Use of Work Equipment Regulations, known as PUWER.
Regulations put a responsibility on both the operator and owner of a lift or crane. These include, only purchasing CE/UKCA marked equipment and only using equipment for its intended use. Operations must be planned, and risk assessed, with operators trained to ensure competence.
Owners must adhere to the manufacturers service and inspection schedule. The initial inspection, completed when a crane is first installed on a vehicle, is particularly important, checking the stability and security of mountings in an over-load. All equipment must be inspected annually, in accordance with LOLER, by a competent person with records kept.
