6.9.2 Storage and Handling
When not in use, electric power operated hoists should be returned to storage or parked in a safe position such as at the end of a runway. When the hoist is parked, the hook should be raised so as not to be a danger to persons who may be walking by or working in the area and to ensure it cannot become accidentally engaged with any items which may be in the vicinity. In the case of chain, the slack chain should be housed in the slack chain collecting box if fitted. Where no slack chain collecting box is fitted, care must be taken to ensure the hanging loop of chain does not present a danger.
When electric power operated hoists are returned to storage, the conditions should meet the requirements for storage recommended in section 1.7.2 Storage and Handling of this code together with the following additional requirements:
Electric power operated hoists being returned to storage should be clean, dry and protected from corrosion. Beware of cleaning and drying processes which might damage the hoist or its electrical components.
Any specific manufacturer’s commissioning or decommissioning instructions should be followed.
All electrical functions of the hoist should be checked prior to storage; in particular hoist limits, brakes and pendant cable control. Attention should be given to all electric cables, particularly where they enter the hoist or pendant control box, to make sure no damage has occurred in use. Plug in cables and pendant cables should be removed and stored separate to the hoist to prevent possible damage. The electric power operated hoist should be labelled to show the date on which it was checked and signifying its readiness for use, but after extended storage or where there may be doubt as to the condition before further use, it is advisable to carry out earth continuity and insulation tests to the main electrical components in addition to the pre-service functional tests detailed in 6.8.3 Post Installation Checks.
Exposed surfaces, including chains and wire ropes, liable to corrosion should be suitably protected before going into storage. In the case of electric power operated wire rope hoists, the bottom hook should be raised to its highest position. In the case of electric power operated chain hoists, if the design and storage arrangements permit, the bottom hook may be raised to its highest position and the slack chain housed in the slack chain collecting box if fitted. Where this is not possible, the hook should be raised to within 350 - 500 mm of its highest position, the slack end of chain then wound around the remaining load chain between the hoist body and hook and secured in place with suitable twine or wire.
It is recommended that electric power operated hoists are stored suspended from the suspension fitting so that the bottom hook and, where applicable, the chain box are clear of the ground thus preventing damage in storage. Where this is not possible, as in the case of larger units with built in trolleys, the hoist should be stored on a purpose built rack or pallet suitably packed so as to keep it clear of the ground.
When being handled, electric power operated hoists should be treated with care. Ensure they are not dropped or thrown down and that the chain or wire rope, bottom hook and pendant cable control are not dragged across the floor.
Whilst being transported and during storage, electric power operated hoists should, if necessary, be covered to prevent the ingress of moisture, dust or other foreign particles.
