higher filling results in an increased working resistance of the grease and thus in
a much higher running temperature.
How to lubricate the chain drive
The service life of the chain drive depends, among other things, on good main-
tenance and lubrication. Lubrication intervals, type of lubricant and method of
lubrication depend on chain speed and operating conditions. Exposed chains
and special chains have to be relubricated after approx. 10 operating hours (or
once per shift), protected chains after approx. 400 to 800 operating hours. The
chain must be thoroughly cleaned before each lubrication. Under normal condi-
tions, for example mineral oil VG 220 can be used. For higher or lower tempera-
tures, special lubricants are to be applied. The lubricant is applied with an oil can
or a brush between roller link plate and outer link plate on the inner side of the
chain.
In case of manual lubrication, the maintenance staff should use the lubricants
known and proven in the factory.
How to lubricate the linear guide
The initial lubrication will be sufficient for an average height of lift of 300,000 m.
The intervals applied to ball guides for relubrication or change of lubricant de-
pend on many factors. These are for example load, speed, temperature and
environmental stress.
The relubrication intervals must be adapted to the respective operating condi-
tions. KP2N-30 lubricant is to be used. The approximate grease quantities are
indicated in the following table.
