How to maintain the tower crane slewing ring? Here are 9 points for reference

(1) Tower crane maintenance technology slewing bearing installation support must be rigid and the mounting surface should be smooth.Before assembling the slewing bearing, the bearing should be de-stressed, and the maintenance of the tower crane can reduce the deformation of the slewing bearing.The contact surface of slewing ring must be cleaned during assembly.

(2) The changes of noise and rotary resistance moment should be paid attention to during the use of tower crane maintenance technology, tower crane maintenance if there is abnormal phenomenon should be removed and checked.

(3) The lifting and maintenance technique of tower crane rotating support must be lifted horizontally or stored, no vertical lifting or storage,to avoid deformation.

What are the selection tips for slewing ring bearings?

In the mechanical industry, slewing bearing has been widely used, because the development of slewing ring, varieties are increasing, and how to choose the slewing bearing using in machinery, we must have some understanding.Let me follow FRB Bearings staff to learn about some of the slewing bearing selection techniques.

Bearing type selection
Bearing type is generally chosen by the user's technical personnel according to the use conditions of the supporting products and the bearing load.The sales mainly know whether the actual load of the user is consistent with the selected bearing. If the bearing fails to meet the use demands, the customer should be advised to change the model as soon as possible.
