3.10.1 Pre-use Inspection
In addition to the thorough examination required under statutory provisions, all chain hoists should be visually inspected by a suitably qualified and experienced person prior to use. For hoists in regular use it is good practice to make the inspection at the start of each shift or working day. For hoists used infrequently it should be done before use on each day of use.
It is recommended that a formal system of pre-use inspection is implemented, and a written record kept identifying the date inspected, confirmation that it passed inspection and the name and signature of the person making the inspection. In the event that it does not pass inspection, there should be a procedure to quarantine the hoist to prevent further use of the equipment until the problem has been resolved.
The purpose of the pre-use inspection is to test the functionality of the hoist and make a visual check for any obvious defects and if any of the following faults are present, the hoist shall be withdrawn from service and referred to a competent person.
The load chain is worn or damaged. In particular, attention should be given to the wear which occurs on the bearing surfaces inside of the links and to damage in the form of bent, notched, stretched or corroded links. The chain should articulate freely.
Obvious signs of ‘opening out’ of hooks, that is any noticeable increase in the throat opening, or any other form of distortion in the hooks or suspension fittings.
Obvious signs of damage to the slack end anchor which connects the load chain to the hoist casing or to the load chain stop where one is fitted.
The hand chain is worn or damaged, particularly on the bearing surfaces on the inside of the links, or is corroded, bearing in mind possible damage to the operative’s hands.
When operated under load there is any jumping or excessive noise of either the hand chain or load chain, any undue effort is required or any visible slipping of the brake.
General damage to the hoist body, including any gear covers or chain guides.
The load chain wheel should be checked for debris in the pockets. Any build-up of debris will prevent the load chain from seating correctly and should be removed.
In certain circumstances, very rapid wear of the load chain can develop, which is characterised by a rough appearance on mating surfaces inside of the links. If such circumstances are suspected, then the equipment should be withdrawn from service immediately and referred to a Competent Person.
