The invention discloses a forklift and a fork control device of the forklift. The fork control device of the forklift, comprises a hydraulic pump, an oil tank, a manual reversing valve, a lifting oilcylinder, a fork, a fork frame, a chain, a chain wheel, a mast, a generator, a regulator, a diode, a storage battery and an electromagnetic valve; an execution port of the manual reversing valve communicates with an oil inlet of the electromagnetic valve, an execution port of the electromagnetic valve communicates with a rodless cavity of the lifting oil cylinder, and the generator is electricallyconnected with the input end of the regulator; the output end of the regulator, the diode and the storage battery are electrically connected in sequence to form a loop, one end of the wiring end of the electromagnetic valve is electrically connected to the connection point between the anode of the output end of the regulator and the anode of the diode, and the other end of the wiring end of the electromagnetic valve is electrically connected to the connection point between the cathode of the storage battery and the cathode of the output end of the regulator; and when the wiring end K of the electromagnetic valve loses power, the execution port A of the electromagnetic valve communicates with an oil outlet T. According to the fork control device of the forklift, the fork can automaticallydescend to land when an engine is flame out.
一种叉车及叉车的货叉控制装置,包括液压泵、油箱、手动换向阀、起升油缸、货叉、叉架、链条、链轮、门架、发电机、调节器、二极管、蓄电池和电磁阀;手动换向阀的执行口与电磁阀的进油口连通;电磁阀的执行口与起升油缸的无杆腔连通;发电机与调节器的输入端电连接;调节器的输出端、二极管和蓄电池依次电连接并形成回路,电磁阀的接线端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,电磁阀的接线端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;当电磁阀的接线端K失电时,电磁阀的执行口A与出油口T相通。本发明可实现发动机熄火时货叉自动下降着地。
