Apply Harrington Hoist, Inc. lubricating grease (Part No. ER2CS1951) or an equivalent to industrial
general lithium grease, NLGI No. 0, to the bearing surfaces of the load chain links as indicated by
the shaded areas in Figure 6-2. Also apply the grease to the areas of the load chain (shaded
areas in Figure 6-2) that contact the load sheave. Insure that the grease is applied to the contact
areas in the load sheave pockets.
Machine or gear oil (grade ISO VG 46 or 68 oil or equivalent) may be used as an alternative
lubricant but must be applied more frequently.
Figure 6-2
Chain Grease Application
The chain should be lubricated every 3 months (more frequently for heavier usage or severe
conditions).
For dusty environments, it is acceptable to substitute a dry lubricant.
6.2.2
Hooks and Suspension Components:
Hooks - Bearings should be cleaned and lubricated at least once per year for normal usage. Clean
and lubricate more frequently for heavier usage or severe conditions.
Suspension Pins - Lubricate at least twice per year for normal usage; more frequently for heavier
usage or severe conditions.

Lubrication - Gearbox
6.3.1
The ER2 (with mechanical load brake/friction clutch) uses different gear oil than
the NER2 (with friction clutch). DO NOT use any oil or quantity other than that listed below. New
hoists are prefilled with the correct type and amount of oil.
6.3.2
DETERMINING OIL LIFE
- Refer to Section 6.1.3 when estimating gear oil life based on operations.
6.3.3
NER2 OIL LEVEL
For hoists equipped with a Friction Clutch, the oil level is checked by removing the
oil plug on the side of the hoist as shown in Figure 6-3 for NER2 hoists. The oil level should be just
below the hole when the hoist is level.
