6.2Lubrication – Load Chain, Hooks, and Suspension6.2.1Load 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.

•The load chain should be lubricated every 3 months (more frequently for heavier usage or severe conditions).

•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.
