The invention discloses a hoisting arm and winch leveling system of a special pipe hoisting machine for mountainous regions in the technical field of engineering machinery. The hoisting arm and winch leveling system comprises a hydraulic control system and an electrical control system. The hydraulic control system comprises a main valve, a main pump, a pilot pump, a suspension arm leveling oil cylinder and a winch leveling oil cylinder. The main pump and the pilot pump are connected with a hydraulic oil tank through an oil suction filter. The pilot pump is connected with the pilot valve through the pilot filter; the main valve is respectively connected with the suspension arm leveling oil cylinder and the winch leveling oil cylinder; the electrical control system comprises a power supply, a resistor, a controller, a suspension arm gradienter and a winch gradienter; the power supply is respectively connected with the suspension arm gradienter and the winch gradienter through the resistor; the port of the controller is connected with the fifth part of the main valve so as to control the winch leveling oil cylinder, and the port of the controller is connected with the fourth part of the main valve so as to control the suspension arm leveling oil cylinder. The lifting arm and winch leveling function of the mountainous region pipe lifting machine is added, the practicability and safety of the mountainous region pipe lifting machine are remarkably improved, and the difficult problem of mountainous region ramp construction is solved.
