Product Description: Hydraulic Winch Valve Assembly 803074501 for XCMG QY50K Truck Crane

The 803074501 Winch Valve Assembly is a genuine XCMG hydraulic control component designed specifically for the XCMG QY50K Truck Crane, a 50-ton (50,000 kg) class mobile crane widely used in construction, infrastructure projects, port logistics, and industrial material handling. As a critical valve within the crane‘s hydraulic winch system, the 803074501 winch valve controls the flow, direction, and pressure of hydraulic fluid to the main and auxiliary winch motors, enabling precise hoisting and lowering operations. The QY50K crane is equipped with two independent winches (main and auxiliary) that allow the operator to control lifting speed and load positioning accurately.
