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.
