The invention discloses a forklift hydraulic system and a forklift, the forklift hydraulic system comprises an oil supply assembly, the oil supply assembly comprises a liquid storage tank and a liquid pump, and the liquid pump communicates with the liquid storage tank; the oil inlet end of the multi-way control valve is communicated with the liquid pump, the oil return end of the multi-way control valve is communicated with the liquid storage tank, and the multi-way control valve is used for achieving front-back movement, lifting, inclination and lateral movement of the portal frame; the oil inlet end of the hydraulic brake valve is communicated with the liquid pump, the oil return end of the hydraulic brake valve is communicated with the liquid storage tank, and the hydraulic brake valve is used for achieving forklift braking. According to the forklift hydraulic system, the loading and unloading functions of hydraulic braking, front-back movement, lifting, inclination, lateral movement and the like of the portal frame can be achieved only through one liquid pump, the integration degree is high, pipelines are simple, and the system saves energy.

    本发明公开了一种叉车液压系统和叉车,叉车液压系统包括:供油组件,所述供油组件包括:储液罐和液泵,所述液泵和所述储液罐连通;多路控制阀,所述多路控制阀的进油端和所述液泵连通且回油端和所述储液罐连通,所述多路控制阀用于实现门架前后移、升降、倾斜和侧移;液压制动阀,所述液压制动阀的进油端和所述液泵连通且回油端和所述储液罐连通,所述液压制动阀用于实现叉车制动。叉车液压系统仅用一个液泵就能实现液压制动和门架前后移、升降、倾斜、侧移等装卸功能,集成化程度较高,且管路简单、系统节能。
