LUBRICATION TO CRANE
Lubrication
• Once a year for winch reduction gears,
and
• Once every 2 years for slewing reduction
gears.
★
After that, replace gear oil:
★
Air enters in and out of the gear case so
that dirt and moisture are brought in the
gear case.
In addition, since hydraulic equipment
gradually wears to produce worn particles,
replace gear oil 6 months after the start of
operation.
