7.3 Load Chain

7.3.1 Lubrication and Cleaning

 Clean the chain with an acid-free cleaning solution. The load chain should be kept clean and

lubricated.

 Lubrication - Clean and lubricate the load chain per Section 6 at least once every 3 months for

normal usage. Clean and lubricate more frequently for heavier usage or severe conditions.

When replacing load chain, check for wear on mating parts, i.e. Load Sheave,

Chain Guides and Idler Wheels, and replace parts if necessary. Remove old chain. Remove hook

set assemblies, limit locks, stoppers and end connections from the chain for reuse on new chain. If

the load chain is being replaced due to damage or wear out, prevent its reuse by destroying the old

chain.
