Lubricating The Slew Drive
NOTICE
REGULARLY LUBRICATE THE SLEW DRIVES TO PROLONG THEIR SER-
VICE LIFE AND ENSURE SAFE OPERATION.
NOTICE
ALWAYS USE THE LUBRICANTS SPECIFIED IN THE ORDER DRAWING. IF
USING OTHER LUBRICANTS PAY ATTENTION TO THE RELATIVE MIX
ABILITY OF THE SUBSTANCES. THE STANDARD LUBRICANTS USED ARE
"R.TECC NORPLEX LKP2" FROM RHENUS, OR THE GREASE "OPTIMOL
LONGTIME PD0" FROM CASTROL. IF IN DOUBT, OR IF THERE IS NO
SPECIFICATION ON THE DRAWING, CONSULT WITH OUR CUSTOMER
SERVICE. USING THE WRONG LUBRICANT MAY CAUSE DAMAGE TO THE
SLEW DRIVES AND REDUCE THE SERVICE LIFE. IN THIS CASE, ANY
WARRANTY SHALL BE EXCLUDED. COMPLY WITH THE INSTRUCTIONS
PROVIDED BY THE LUBRICANT MANUFACTURER!
•
If possible use a central lubrication system to lubricate
the raceway system. In this regard ensure that the
hoses are filled with grease at commissioning and
that the storage tanks are regularly topped up with
grease.
•
An automatic re-lubricating system significantly facili-
tates re-lubrication for the raceway system and the
toothing. Functional safety as well as wear behavior
are improved.
•
Comply with the instructions in the operating manual
provided by the respective manufacturer for lubrica-
tion of optional intermediate gear units, brakes, and
motors.
•
If it is evident that moisture has penetrated into the
slew drive, or has been absorbed by the grease, you
must re-lubricate more intensively.
