The invention relates to an electro-hydraulic proportional control forklift, in particular to a forklift electro-hydraulic proportional control valve group. A safety control valve of the forklift electro-hydraulic proportional control valve is connected in an LS oil way, one end of the safety control valve is connected to a pressure compensation valve, the safety control valve is a two-position four-way electromagnetic valve, one station of the safety control valve is in a Y shape, and the other station of the safety control valve is in a one-way on-way and one-way off-way shape. The valve group of the electro-hydraulic proportional control forklift is optimized, and it is guaranteed that the valve group cannot be started due to mistaken touch.

    本发明涉及电液比例控制叉车,尤其涉及一种叉车电液比例控制阀阀组。叉车电液比例控制阀的安全控制阀,它连接在LS油路中,其一端连接至压力补偿阀,所述安全控制阀是个两位四通电磁阀,它的一个工位是Y型,另一个工位为一路通一路断型。本发明针对电液比例控制叉车的阀组进行优化,保障不会因误触碰而启动。
