Product Detail

Product Description: Steering Gear Assembly 80300382 (NT110X) for XCMG QY50B Truck Crane

The Steering Gear Assembly (型号: 80300382) is a genuine OEM component engineered for the XCMG QY50B Truck Crane, a 50‑ton (55 US‑ton) class mobile crane widely used in construction, urban infrastructure, ports, bridge building, oilfields, mining and other heavy‑lift applications. As the core hydraulic control unit of the vehicle's power steering system, this assembly — also known by its interchangeable part number NT110X — converts the operator's steering wheel input into precisely regulated hydraulic signals that direct the steering cylinders, enabling smooth and responsive turning of the crane's multi‑axle chassis.
