SHIP CRANE

FINE slewing ring bearing is an essential and strategic part because of the light structure of the crane. FINE slewing rings are widely used in kinds of cranes, such as tower cranes, ship deck cranes, mobile cranes, railway cranes and so on.
Large shipboard crane will use a triple row external gear roller slewing ring. The high load capacity and compact proportions of this type of slewing ring are ideally matched to the mast and base block proportions of the crane.
The vessel was fully loaded and on voyage to the discharge port, where the use of the impaired crane was absolutely necessary, as harbour cranes were not available for dockside discharge
Class-certification is available for all bearings, at additional cost. If the original calculations for the bearings are no longer available, we can have them recalculated by our own structural engineers.
