The invention discloses a hydraulic lifting platform. The hydraulic lifting platform is connected with four hydraulic lifting devices through reserved ports. A hand pump is used for providing power for the hydraulic platform to rise and fall. The inclination angle of the platform is controlled by controlling the rising and falling height of front and rear wheels. Throttling valves are controlled to drive the cargo platform to fall to return to the original position. The traveling direction of the cargo platform is controlled by controlling the rear wheels in the traveling process. The platformcan be replaced as required. Through the hydraulic lifting platform, cargos can be loaded and unloaded to an airplane more conveniently.
本发明公开了一种液压升降平台,平台通过预留接口与四个液压升降装置连接,通过手摇泵为液压提供动力使平台升降,控制前后轮的升降高度控制平台的倾斜角度。控制节流阀使货台下降复归原位。平台行走过程中通过控制后轮控制货台行驶方向。平台可以根据需要更换。采用本发明能够使货物上下飞机更加方便。
