Product Detail

Product Description: Steering Gear Assembly 80300654 for XCMG QY25K Truck Crane

The Steering Gear Assembly 80300654 is a genuine XCMG OEM component engineered for the QY25K series truck crane, a 25‑ton class mobile crane widely used in construction, port logistics, bridge building, oilfields, and industrial material handling. As the core control unit of the vehicle‘s hydraulic power steering system, the steering gear assembly converts the operator’s steering wheel input into precisely controlled hydraulic signals, directing the steering cylinders to execute smooth left and right turns. This assembly is designed to withstand the high cyclic loads, vibration, and environmental exposure typical of heavy‑duty crane operations, ensuring reliable and fatigue‑reducing steering performance on both public roads and rough job sites.
