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.

    一种升降车的停车制动装置,包括发电机、调节器、二极管、蓄电池、电磁阀、蓄能器、停车制动器、停车液压缸、手动换向阀和油箱;调节器的输出端、二极管和蓄电池依次电连接并形成回路,且二极管的阳极与调节器的输出端的正极电连接,二极管的阴极与蓄电池的正极电连接;电磁阀的接线端K的一端电连接在调节器的输出端的正极和二极管的阳极的连接点。还包括磁钢和接近开关;电磁阀的接线端K的另一端与接近开关的一端电连接,接近开关的另一端电连接在蓄电池的负极和调节器的输出端的负极的连接点;磁钢与接近开关相对应。本发明既能实现熄火时自动进行停车制动,又能实现升降车在进行升降作业时自动具有停车制动。
