12.10.3 Maintenance

A routine preventive maintenance programme should be drawn up. This can be combined with the maintenance programme that will be necessary for the lifting appliance. It should meet the requirements set out in the manufacturer’s installation and maintenance instructions in addition to any requirements of the particular site due to the conditions of service. In any event attention should be given to the following points:

  1. In particular, attention should be given to the lubrication of wheel and castor bearings, which should turn and swivel freely.

  2. Screw jack threads should be cleaned, free of any debris and lubricated; ball joints should also be lubricated as necessary.

  3. The general condition of the structure should be maintained in good order. Where necessary, paint work should be rubbed down and repainted.

  4. The face of the runway track on which the trolley runs must be cleared of all debris or other matter which may impede the smooth operation of the trolley. The track face should not be lubricated or painted as this may cause the trolley wheels to slip or skid.
