8.10.4 Maintenance

Routine preventive maintenance should be carried out according to the manufacturer’s instructions in addition to any requirements of the particular site due to the conditions of service. For in-situ trolleys and hoists, this maintenance can be combined with the maintenance programme that will be necessary for the hoist. In any event attention should be given to the following points:

  1. The trolley should be thoroughly cleaned and moving parts lubricated. Particular care must be taken to avoid contamination of the running surfaces of the wheels and the flanges of the runway beam with lubricants.

  2. In the case of in-situ trolleys, if the trolley wheels or runway are contaminated with debris, lubricant or other fluid that could cause wheel slip, the wheels and beam should be cleaned.

  3. If there is any distortion or appreciable wear of the runway beam on which the trolley is fitted, remove the trolley from service and refer to a Competent Person. If the runway end stops are missing, are ineffective or make contact with the trolley wheel flanges they should be replaced.
