EXTRAORDINARY INSPECTION
In case of extraordinary events which can jeopardise the safety of the working equipment, extraordinary
testing must be carried out. In particular, extraordinary events include accidents, modifications to the hoist,
prolonged downtime periods and natural phenomena.
Testing must be carried out only by authorised personnel, duly authorised for the purpose.
In addition to the above inspection and testing procedure, a preventive maintenance program should be
established to prolong the useful life of the hoist and maintain its reliability and continued safe use. The
program should include the periodic and frequent inspections with particular attention being paid to the
lubrication of the various components using the recommended lubricants.
