The invention relates to the technical field of hydraulic control, and discloses a hydraulic integrated system which comprises an oil tank, a hydraulic pump, a first multi-stage hydraulic cylinder, asecond multi-stage hydraulic cylinder, a balance valve, a limit switch, a hydraulic integrated block and a pressure control assembly. An oil hole A communicates with rodless cavities of the multi-stage hydraulic cylinders, and an oil hole B communicates with rod cavities of the multi-stage hydraulic cylinders through the balance valve; a first oil inlet cartridge valve, a second oil inlet cartridge valve, a first oil return cartridge valve and a second oil return cartridge valve are arranged in the hydraulic integrated block, and the hydraulic integrated system further comprises a first electromagnetic directional valve, a second electromagnetic directional valve, a third electromagnetic directional valve and a fourth electromagnetic directional valve; and the pressure control assembly comprises a fifth electromagnetic directional valve, a pressure cartridge valve and an overflow valve. According to the hydraulic integrated system, the direction, flow and pressure of oil are controlled, so that a cargo compartment can be stably lifted and lowered, the structure is simple, and operation is stable.
