Product Detail

Product Description: Rotary Reducer 800300097 for XCMG Crane

The Rotary Reducer 800300097 is a genuine OEM planetary gearbox component engineered for the slewing (rotating) mechanism of XCMG cranes, including truck-mounted cranes, all-terrain cranes, and crawler cranes. As the core power transmission unit of the crane‘s slewing system, the rotary reducer converts the high-speed, low-torque output of the hydraulic slewing motor into low-speed, high-torque rotational motion, enabling smooth, powerful, and precise 360° rotation of the crane’s upper structure—including the cab, boom, and load—relative to the fixed undercarriage.
