Danger of the slewing bearing being ripped off.
If while checking you notice very loose, broken or missing screws, then the
slewing bearing
has been overloaded and is no longer safe to use. During
crane operation, the slewing bearing may rip off suddenly and thus cause
fatal accidents.
Do not put the truck crane back into operation and have the slewing bearing
repaired by
Manitowoc Crane Care.
