2.8.2 Cranes
Electric bridge and gantry cranes should be installed by appropriately qualified personnel. Usually, the supplier of the crane will undertake the installation and ensure that all appropriate post-installation tests and checks are carried out and recorded. However, it is the employer’s duty to make sure that this is done and to obtain a report of thorough examination stating that it has been properly installed and is safe to use.
The post installation tests and checks will include but may not be limited to:
Assessment of the installation for compliance with the established design criteria, dimensions, etc.
Proving tests of all controls, limit switches and emergency stop controls.
Appropriate electrical safety checks.
Operation of the crane under full load conditions including checking of specified hoist and travel speeds.
Overload testing of the crane and supporting structure.
Compliance with relevant legislation.
The procedure for overload testing and the amount of load to be applied will depend upon the standard to which the crane was manufactured. It is therefore recommended that before testing any crane that you consult with the manufacturer or suitable LEEA member to ensure that the nature and extent of any testing is appropriate.
