LUBRICATION
To ensure continued satisfactory operation of the hoist, all
points requiring lubrication must be serviced with the
correct lubricant at the proper time intervals indicated for
each assembly. Correct lubrication is one of the most
important factors in maintaining efficient operation.
The lubrication intervals recommended in Table 6 are based
on intermittent operation of the hoist eight hours each day,
five days per week. If the hoist is operated almost
continuously, or for more than eight hours each day, or
under severe conditions, more frequent lubrication will be
required.

Lubricant types and change intervals are based on operation
in an environment relatively free of dust, moisture and
corrosive fumes. Use only those lubricants recommended.
Other lubricants may affect performance of the hoist.
Approval for the use of other lubricants must be obtained
from your Ingersoll-Rand Technical Support Department
or distributor. Failure to observe this precaution may result
in damage to the hoist and/or its associated components.
Whenever a hoist is disassembled for overhaul or
replacement of parts, lubricate as follows:
Brake and Gear Assemblies
The gear and brake assemblies share a common oil bath. On
larger capacity hoists, the output shaft from the motor is
offset and utilizes a pinion gear to drive the sun gear. These
gears operate in the motor casing oil bath.

LCA030S and Larger Hoists Oil Fill Level Positions
Fill to the level of the plug on the side of the motor
housing and on the gear end in the center of the brake
end cover.
Replace the oil in the brake and gear housing in accordance
with Table 6 recommendations. Refer to Table 8 for
recommended oil type. If hoist use is at normal frequency,
the oil in the reduction housing is suitable for one year's
operation without changing.
However, when hoist use is at greater frequency, or under
severe conditions, the oil may need to be changed more
often. To ensure correct performance, highest efficiency
and long life, it is essential that the lubricating oil be
maintained at the correct level. The recommended grade of
oil must be used at all times since the use of unsuitable oil
may result in excessive temperature rise, loss of efficiency
and possible damage to the gears.
Liftchain hoists are shipped from the factory with oil in the
brake and reduction gear assembly.

Hook Assemblies
Hoist top and bottom hooks are supported by thrust
bearings. These bearings must be packed with Ingersoll-
Rand No. 68 Grease or a standard No. 2 multi-purpose
grease at regular intervals. Neglect of proper lubrication can
lead to bearing failure.
1. Lubricate the hook and latch pivot points. Hook and latch
should swivel/pivot freely.
2. Use Ingersoll-Rand LUBRI-LINK-GREEN ® or ISO
VG 220 (50W) lubricant.
3. Lubricate hook bearings by applying several shots of
grease from a grease gun to the grease fittings provided
on the hook blocks.
Air Line Lubricator
If an air line lubricator is used, it should be replenished
daily with ISO VG 100 (30W) lubricant (minimum
viscosity 135 Cst at 104° F (40° C)).
Trolley
Grease the wheel bearings and wheel drive gear with
Ingersoll-Rand No. 68 Grease or a standard No. 2 multi-
purpose grease periodically. Refer to the manufacturer's
literature for additional lubrication information.
Load Chain
WARNING
• Failure to maintain a clean and well-lubricated load
chain will result in rapid load chain wear that can lead
to chain failure which can cause severe injury, death or
substantial property damage.
1. Lubricate each link of the load chain weekly. Apply new
lubricant over existing layer.
2. In severe applications or corrosive environments,
lubricate more frequently than normal.
3. Lubricate hook and hook latch pivot points with same
lubricant used on the load chain.
4. If required, clean chain with acid free solvent to remove
rust or abrasive dust buildup and lubricate the chain.
5. Use Ingersoll-Rand LUBRI-LINK-GREEN ® or ISO
VG 220 (50W) oil.
