The invention discloses a servo hydraulic mast control system. The system comprises a servo winch, a working oil path of the servo winch and a control oil path of the servo winch. The working oil path comprises a hydraulic motor, a one-way adjustable throttle valve and a one-way balance valve, and the hydraulic motor, the one-way adjustable throttle valve and the one-way balance valve are sequentially connected. The hydraulic motor is connected to a first working oil opening of a multiway valve, and the control oil path comprises a winch brake, a shuttle valve, a pressure reduction valve, an operated overflow valve, a remote overflow valve and a switching valve; the winch brake is connected to the hydraulic motor and sequentially connected with the pressure reduction valve, the shuttle valve, the switching valve, the remote overflow valve, the operated overflow valve and a second working oil opening of the multiway valve; and the operated overflow valve is further connected with the first working oil opening of the multiway valve, and the first working oil opening of the multiway valve is connected with the shuttle valve and the one-way balance valve. The servo hydraulic mast control system is reasonable in structure, easy and convenient to operate and control and capable of completing manual control operation and servo control operation; all lifting work can be completed only through one person, rapidness and convenience are achieved, the working efficiency is greatly improved, and the manual labor cost is greatly reduced.
