Ingersoll Rand HA1 Manuel D'installation page 9

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

Pivot Points and Bushings
Lubricate grease fittings monthly with 2 or 3 pumps from a grease gun
or more frequently, depending on severity of service.
Hoist and Trolley Drive Motors
Motors are splash lubricated by the oil in the motor housing and have
no other means of lubrication. It is therefore important to use only high
quality, non-detergent hydraulic oil to insure maximum performance
and minimum down time for repairs. Allow oil to settle prior to topping
off.
Hoist:
Oil capacity for the HA1 hoist motor is 0,38 litres (0,1 gals.); the HA2
hoist motor capacity is 0,76 litres (0,2 gals.).
* Hoist motors are shipped from the factory with SAE 20W hydraulic
oil.
Trolley:
Oil capacity for the HA1 and HA2 trolley drive motor is 65 ml (0,1
pints).
Bottom Hook Block Assembly
To prevent moisture entering the bottom block assemblies ensure they
are packed with grease.
Lubricate grease fittings monthly with 2 or 3 pumps from a grease gun
or more frequently, depending on severity of service.
Load Chain
WARNING
• Failure to maintain 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 environment, lubricate more
frequently than normal.
3. Lubricate hook and hook latch pivot points with the same
lubricant used on the load chain.
4. To remove rust or abrasive dust build-up, clean chain with acid
free solvent. After cleaning, lubricate the chain.
5. Use Ingersoll-Rand LUBRI-LINK-GREEN or a SAE 50 to 90 EP
oil.
Trolley Drive Assembly
The gear housing is filled at the factory and shipped with the proper
amount of oil, a non-toxic, rust inhibiting worm gear oil AGMA #7
compound that is suitable for an ambient temperature of 10° to 52° C
(50° to 125° F).
Before placing the hoist in operation, make certain that the breather in
the gear housing is clean and unrestricted.
LUBRICATION
For ambient temperatures of -23° to 10° C (-10° to 50° F) use AGMA
#5 (EP 5).
Fill gear housing through port with breather to the height of level plug
hole located in the cover. The gear housing oil capacity is
approximately 1,5 litres (0,4 gals).
After the first 10 hours of operation, the oil should be changed.
Thereafter it should be changed every 100 hours of service or every 6
months whichever occurs first. The oil is drained by removing pipe plug
located underneath the gear housing. The oil should be replaced using
one of the recommended lubricants or its equivalent.
Trolley Wheels
Lubricate grease fittings monthly with 2 or 3 squirts from a grease gun.
Grease fittings are located on trolley side plates at each trolley wheel
location.
Reduction Gear Assemblies (General)
The reduction gear assemblies are filled and shipped with oil from the
factory. Check levels before operating hoist. If the hoist is used at a
Type Grease
normal frequency replace the oil in the reduction housing once every
EP 1 multipurpose
year.

To ensure correct performance, highest efficiency and long life, it is
EP 2 multipurpose
essential that the lubricating oil be maintained at the correct level.

• Do not over fill. Excess oil will reduce operating efficiency and
increase oil temperature.
Use only high quality lubricants in the reduction gear assembly such as
SAE 90 EP motor oil or high grade EP4 gear oil.
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.
HA1 Reduction Gears
There are two reduction gear assemblies, check oil level on both sides
before initial hoist operation. Brake side oil capacity for the reduction
gear assembly is 1,1 litres (0,3 gals). Motor side oil capacity for the
reduction gear assembly is 0,76 litres (0,2 gals).
Check breathers are clean and unrestricted.
HA2 Reduction Gear
Oil capacity for the reduction gear assembly is 4,2 litres (1,1 gals).
Check vented fill plug is unrestricted.
HA1 Disc Brake Assembly
The brake assembly is sealed from the reduction gear assembly. Check
brake fluid level in disc brake prior to operating hoist. If hoist is used at
a normal frequency replace brake fluid yearly. Use DOT 5 brake fluid.
Capacity is approximately 60 ml (2 fl. oz.).
HA2 Disc Brake
The disc brake housing is filled and shipped with oil from the factory.
Check oil level before operating hoist. If hoist is used at a normal
frequency replace oil yearly. Oil capacity for the disc brake housing is
0,76 litres (0,2 gals).
Fill brake housing to height of level plug.
• Do not over fill. Excess oil will reduce operating efficiency and
increase oil temperature.
Use only high quality lubricants in the disc brake housing assembly
such as SAE 90 EP motor oil or high grade EP4 type gear oil.
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 brake discs.
