The invention relates to an integrated hydraulic control system for a lifting platform. The hydraulic control system comprises a valve block, and a lifting valve, a priority valve, a conversion valve and a walking valve which are respectively mounted on the valve block, the valve block is provided with a valve block oil inlet, a valve block oil return port, a lifting oil port, a first steering oil port, a second steering oil port and a brake release oil port; the lifting valve is used for achieving the ascending and descending functions of the lifting platform and connected with the valve block oil inlet, the valve block oil return opening, the lifting oil opening and the priority valve. The priority valve is used for achieving the steering priority function and connected with the steering valve, the brake release oil port and the walking valve so as to supply oil to the steering valve, the brake release oil port and the walking valve, and the steering valve is connected with the first steering oil port and the second steering oil port. The steering device has steering priority and load sensitive functions, and is small in size and convenient to machine and maintain.
