SLEW DRIVE GEARS
The slew drive gear is designed to be
largely maintenance free. However, we
recommend the gear teeth be greased
on a weekly / monthly basis with a high
pressure grease depending on
operating conditions. Always clean the
gear first to remove any road dirt and
grime. In very dusty or sandy conditions
take care to prevent a build-up of grit /
sand mixed with grease which may
cause premature wear on the gear.
Additionally, the ring gear and gear box should be greased on a six monthly basis. The
grease nipple for the ring gear is on the top face of the slew gear, set between the fixing
bolts. It can be accessed by lifting one of the side covers, and slewing the structure appro-
priately.
The ring gear should be inspected on a six monthly basis for excessive play. It is unlikely
there will be any wear if the machine is maintained correctly.
To check the gear, place a payload of approximately 80Kg in the platform. Elevate the lower
boom to approximately half way. Then gently elevate the top boom, whilst observing the
ring gear. Excessive wear will be observed by noticing more than 0.5mm movement be-
tween the inner and outer bearing rings. If excessive wear is present the gear ring should
be replaced
