●XCMG 800300305 Slewing Reducer Technical Support
●Part number 800300305 (related part code 800300011) is the genuine heavy-duty multi-stage planetary rotary slewing reducer gearbox assembly engineered for XCMG 50-ton truck cranes.
●Material number 800300305 is mounted vertically upon the crane slewing turntable frame with its output pinion meshing precisely into the large slewing ring bearing teeth. It multiplies hydraulic motor drive torque through high-precision planetary gear stages to provide exceptionally smooth, backlash-controlled 360-degree superstructure slewing and precise boom positioning under full working loads.
●Check gear oil lubrication levels, verify output pinion tooth backlash, and inspect dynamic brake release pressure during scheduled crane servicing.
