SCC1000C Crawler Crane — Maintenance Manual
The slewing bearing is lubricated by the pipeline:
1. In normal operating conditions, perform central
lubrication to the slewing bearing when it
operates for every 8 hours.
2. New lubricating grease must be applied
sufciently before and after long-term shutdown
of the machine.
3. For various lubrications, the roller path must be
lled with lubricating grease, until it oozes from
the seal.
4. While filling lubricating grease, make sure to
slowly rotate the slewing bearing, so that the
lubricating grease is lled equally.
5. Frequently check the integrity of the sealing, if
the sealing tape is found to be damaged, replace
it immediately, if it is found to fall off, restore it in
time.
6. Lubricate the slewing surface by oil feed pipe.
7. The slewing bearing pinion surface should be
cleaned every 250 operating hours, and be
applied with lubricating grease.
