6.2 Lubrication

6.1.1 Lubricate the following trolley components with only Nevastane HT/AW 2 White Drum food grade

lubricating grease.

6.1.2 Track Wheel Gear – Clean and re-grease the Track Wheel gears and motor output pinion every

three months (more frequently for heavier usage or severe conditions). Do not use an excessive

amount of grease and avoid getting any grease on the running surfaces of the Track Wheels or

the beam.

6.1.3 Gear Box – The reduction gearing in the motor should be cleaned and lubricated at least once

per year for normal usage. Clean and lubricate the reduction gear assembly more frequently for

heavier usage or severe conditions. Gain access to the gears by removing the four bolts that

mount the motor assembly to the trolley Side Plate. Make sure to properly orient and reuse the

neoprene gasket between the motor and Side Plate.

6.1.4 Suspension Pins, Bolts and Shafts – Grease at least twice per year for normal usage (more

frequently for heavier usage or severe conditions).
