Chain Warnings:
Caution: It must be recognized that certain factors in the usage of chain and attachments can be
abusive and lessen the load that the chain or attachments can withstand. Some examples are twisting
of the chain, disgurement, deterioration by straining, usage, weathering and corrosion, rapid applica-
tion of load or jerking applying excessive loads, and sharp corners cutting action.
Due to the crushing effect Grab Hooks have upon chain, the design factor of all assemblies must be
reduced by 20% for Grab Hook applications.
Use the following chart to determine when the chain must be replaced. Replacement of the
entire chain is necessary if any of the previous page problems are found or the maximum
dimensions on the charts that follow are reached.
