Technical Advice: When installing the retaining ring, ensure the pin face and the kingpost seat are free of burrs and old grease deposits. Proper tightening of the collar locking bolt is essential to prevent play, which can lead to the wearing out (ovalization) of the holes in the kingpost structure. Regular inspection of the rings is recommended during each lubrication of the swing system – any cracks or deformations of the collar signify a need for replacement to prevent the pin from sliding out during boom operation.
