Lubricants for the chain
For information on the lubricants that are delivered with the chain hoist, see chapter Lubricant information.
Checking the lubrication of the chain
Maintaining the chain is one of the most important service tasks of a chain hoist. Lubrication, including the initial
lubrication of the chain, is part of the chain maintenance. If you do not maintain the chain properly, the lifetime of
the chain and the complete chain drive of the hoist reduces drastically. Failing to maintain the chain can result in a
failure of the chain.
Check the proper and sufficient lubrication of the chain visually between the chain links:
Well lubricated
Completely dry and damaged
Figure 4. Checking the chain lubrication
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.
Conditions that have an influence on the needed chain maintenance are, for example, the following (but not limited
to these):
Environment (clean or dusty, cold or hot, indoor or outdoor use)
Use of the hoist (light or full loads, high process cycles or low maintenance use)
Construction of the hoist (number of chain sprockets).
The condition of the chain is evaluated visually, combined with regular measurements. For more information on
inspecting the chain wear, see chapter Inspecting chain wear.
