A parking brake device of a lift truck comprises a generator, a regulator, a diode, a storage battery, an electromagnetic valve, an energy accumulator, a parking brake, a parking hydraulic cylinder, amanual reversing valve and an oil tank. The output end of the regulator, the diode and the storage battery are electrically connected in sequence to form a loop, the anode of the diode is electrically connected with the positive electrode of the output end of the regulator, and the cathode of the diode is electrically connected with the positive electrode of the storage battery; and one end of the wiring end K of the electromagnetic valve is electrically connected to a connection point of the positive electrode of the output end of the regulator and the anode of the diode. Magnetic steel anda proximity switch are further included; the other end of the wiring end K of the electromagnetic valve is electrically connected with one end of the proximity switch, and the other end of the proximity switch is electrically connected to a connecting point of the negative electrode of the storage battery and the negative electrode of the output end of the regulator; and the magnetic steel corresponds to the proximity switch. Automatic parking braking can be achieved during flameout, and automatic parking braking can also be achieved during lifting operation of the lift truck.
