Figure 22. Completely dry and damaged chain
Lubrication intervals of the chain
Defining the required maintenance interval for the chain depends on the use of the product, and
must be determined case-by-case. To fully optimize the lifetime of the components, define the
exact maintenance interval for each hoist application individually.
The following conditions are examples of operating conditions that have an influence on the
required chain maintenance:
• Environment (clean or dusty, cold or hot, indoor or outdoor use)
• Use of the chain hoist (light or full loads, high process cycles, or low maintenance use)
• Construction of the chain hoist (number of chain sprockets)
Evaluate the condition of the chain visually. Combine the visual checks with regular
measurements. For more information, see chapter Inspecting the chain wear.
The following table describes the suggested lubrication intervals of the chain. The data is based
on use of the chain hoist as an industrial indoor application. It is assumed that the chain hoist is
operated under conditions where there are no external particles and where the hoist is in
continuous use with full load.
