Maintenance 6.1-4
Correct lubrication of the crane bearings:
•
Before lubricating clean the area to be lubricated thoroughly because dirt injected into the bearing
with the new lubricant will lead to rapid wear of the bearings.
•
Inject fresh grease into the bearing at the lubrication points provided (lubrication nipples etc.) until
it flows out of the bearing.
Correct lubrication of the pillar bearing (gear rack, stop ring)
•
Before lubricating the pillar bearing raise the boom to its full height so that the lubricaton grease
can spread evenly in the bearings. The pillar bearing should be lubricated via the lubrication
points provided by Palfinger. If you lubricate by means of central lubrication ensure that adequate
lubrication takes place.
•
After you have injected grease into all lubrication points for the first time slew the crane through
the full slewing range. Then repeat this process as often as necessary until grease comes out
between the crane pillar and crane base.
Example:
After lubrication excess grease must be
cleaned off the bearings.
Correct lubrication of the crane’s hydraulic extendable arms:
•
Extend the hydraulic extendable arms completely and then rest the load arm on a piece of wood.
•
Before lubrication clean the lubrication points to remove old dirty grease and other dirt.
•
Then apply grease to the underside of the hydraulic extendable arms with a
suitable aid (brush etc.).
•
Now retract the hydraulic extendable arms under slight pressure (lower boom).
