6.2 Lubrication – Load Chain, Hooks, and Suspension
6.2.1 Load Chain
• For longer life, the load chain should be lubricated.
• The load chain lubrication should be accomplished after cleaning the load chain with an acid
free cleaning solution.
• Apply only Harrington Hoist, Inc. food grade lubricant (Part No. 2AFG003S1951) to the bearing
surfaces of the load chain links as indicated by the shaded areas in Figure 6-2. Also apply the
lubricant to the areas of the load chain (shaded areas in Figure 6-2) that contact the load
sheave. Ensure that the lubricant is applied to the contact areas in the load sheave pockets.
Figure 6-2 Chain Grease Application
• The load chain should be lubricated every 3 months (more frequently for heavier usage or
severe conditions).
6.2.2 Hooks and Suspension Components
• Hooks – Bearings should be cleaned and lubricated at least once per year for normal usage.
Use only Nevastane HT/AW 2 White Drum food grade lubricating grease. 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.

6.3.2 DETERMINING OIL LIFE - Refer to Section 6.1.3 in the ER2OM when estimating gear oil life
based on operations.
6.3.3 NER2 OIL LEVEL – 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.
