ROTATION SYSTEM LUBRICATION
There is one grease fitting on the right-hand side of the rotation bearing. This should be
used to lubricate the bearing every 50 hours. Rotate the turntable 90 degrees while
pumping grease into the fitting. Use about 3 ounces (89 mL) of grease each time the
bearing is lubricated.
Also, lubricate the four grease fittings on each end of the two swing cylinders.
TORQUE HUBS
Use Mobilube
HD 80W-90 gear lube
or equivalent
SAE 80W-90.
On new cranes, drain oil
after first 50 hours of
use and refill.
Check oil level every 50
hours.
Drain and refill after
1,000 hours of operation
or after one year of ser-
vice, whichever comes
first.
WIRE ROPE LUBRICATION
The wire rope should be cleaned and lubricated every 50 hours of normal operation and
more frequently when used in dirty or corrosive environments. Whenever the rope is dirty
or dry, it should be serviced.
The rope should be cleaned with solvent and compressed air or solvent and rags. A wire
brush may be used for difficult areas.
The recommended lubricant is AMOVIS #2-X. It should be sprayed or dripped onto the
rope where it is bent, as it passes over the tip sheave. Wrap rags around the wire rope
behind the sheave and swab the excess oil that is carried along on the rope. Always
wear heavy leather gloves when handling wire rope.
