ROTATION BEARING LUBRICATION
There is one grease zerk in a hole on the right-hand side of the turntable base plate.
This should be used to lubricate the bearing every 50 hours. Rotate the turntable about
45 degrees and pump some grease into the zerk. Repeat until the turntable has rotated
two revolutions. Use about 4 ounces of grease each time the bearing is lubricated.
Also, lubricate the gear teeth of the rotation bearing at the 50 hour interval. Remove the
pinion cover. Brush open gear grease, such as Mobilkote-S, on the teeth on each side
of the pinion at four places around the bearing. Rotate the boom several times and
check the coverage of the grease on all of the teeth. Replace the pinion cover.
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.
