The invention provides a hydraulic unloading shuttle valve, mainly solves technical problems of guaranteeing the tightness of a lift valve and the flexibility and convenience of the opening and closing of the lift valve, and adopts a technical scheme that: the shuttle valve is arranged on a lift valve body; a valve core, a left crown bar and a right crown bar are arranged in a shuttle valve body; a left hole and a right hole are reserved at ends of the left crown bar and the right crown bar; a left through hole, a middle hole and a right through hole are reserved on the shuttle valve body; the left through hole is communicated with a high-pressure cavity of the lift valve body; the right through hole is communicated with a low-pressure cavity of the lift valve body; and the middle hole is communicated with a sealed annular cavity. When the valve core of the shuttle valve moves rightwards, the high-pressure cavity and the annular cavity are communicated; and when the shuttle valve moves leftwards, the low-pressure cavity and the annular cavity are communicated. The hydraulic unloading shuttle valve is suitable for various lift valves.
