SLEWING DRIVE TECHNICAL - QCB – Slewing rings and drives

Slewing rings should not be suspended from a crane by a single sling or placed on the ground vertically as they may deform under their own weight. Flatness defects Under load, flatness defects must not exceed the values tabulated to avoid tight spots or seizure, both of which will reduce the operating life of the ring.
