How often should I torque the bolts on a crane slewing ring?
Torque slewing ring bolts initially after 50-100 operating hours, then every 500 hours or annually, whichever comes first.
Slewing ring bolt torque maintenance follows a specific schedule to prevent bearing failure and ensure safe operation. Initial re-torquing should occur after the first 50-100 operating hours when the crane is new or after bearing replacement, as bolts naturally settle during the break-in period.
Remember: "50-100 First, then 500 Each Year" - Initial check after break-in, then regular annual intervals.
