CAUTION
• Do not use hoist if hook latch is missing or damaged.
7. CHAIN REEVING. Ensure welds on standing links face in toward load sheave.
Reinstall chain if necessary. On double fall hoists, make sure chain is not capsized,
twisted or kinked. Adjust as required. Refer to Dwg. MHP0043 on page 9.

8. BRAKE SYSTEM. Check to ensure the brake is able to hold the rated load without
slippage. Check air gap.
CAUTION
• Should the brake solenoid hum, buzz or vibrate, then the air gap (S) must
be reset in accordance with Table 5 on page 6.
• Humming of the motor or slow lifting speed indicates oily or sticky brake
discs or worn or damaged brake cage. Dismantle and ensure brake discs
are clean and dry. Brake cage must be replaced if damaged.
9.
LIMIT SWITCH. Check to ensure chain stopper is securely attached to chain. On
double fall hoists ensure lower hook sheave block capscrews are tightened to
the correct torque. Refer to Table 6 on page 6 for torque specifications.
10. SLIP CLUTCH. The slip clutch is factory pre-adjusted to slip at a nominal 140%
of the hoist rated capacity. If the wear resistant lining is overheated the slip load
will be reduced.
CAUTION
• Adjustment of the slip clutch should only be attempted by a service
designated personnel and must be recorded in the inspection report.
11.
SUSPENSION PARTS. All statically loaded parts are known as suspension parts.
Refer to Table 6 Capscrew Torque Chart on page 6. Torque values are for Grade
8.8 capscrews.
LUBRICATION
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. The lubricant types 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 provide proper
lubrication may result in damage to the hoist and/or its associated components.

Hook and Suspension Assemblies
1. Lubricate the lower hook and hook latch pivot points. Hook and latch should
pivot freely.
2. Use Ingersoll Rand LUBRI-LINK-GREEN or a SAE 50 to 90 EP oil.
n
Trolley (optional feature)
Refer to the manufacturer’s literature for correct lubrication. For additional
information on Quantum motorized trolleys, refer to Parts, Operation and
Maintenance Manual Form Number MHD56108.

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 latch pivot point with the same lubricant used on the load chain.
4. To remove rust or abrasive dust build-up, clean chain with an acid free solvent.
After cleaning, lubricate the load chain.
5. Use Ingersoll Rand LUBRI-LINK-GREEN or a SAE 50 to 90 EP oil.
n
Gears
The gear compartment is filled with grease at the factory to provide continual
lubrication. Replacement of the grease for the life of the hoist should not be required.

If it becomes necessary to remove the gear end cover, first ensure the hoist body is
standing on end with the gear end cover up. Failure to observe this procedure will
allow the grease to flow from the hoist. Whenever the gear end cover is removed,
always replace the cover gasket.
CAUTION
• Use extreme care when removing gear end cover to avoid grease spillage.

LIMITED WARRANTY
Ingersoll Rand Company (“IR”) warrants to the original user its industrial lifting
equipment (“Hoist”) to be free of defects in material and workmanship for a
period of one year from the date of purchase. IR will, at its option either (1)

charges, or (2) replace such Hoist or refund the purchase price, less a reasonable
allowance for depreciation, in exchange for the Hoist. Repairs or replacements
are warranted for the remainder of the original warranty.
If any Hoist proves defective within its original one-year warranty period, it should
be returned to any Authorized Hoist Service Distributor, transportation prepaid with
