The invention discloses a forklift hydraulic system, and relates to the technical field of forklifts. The device comprises an oil tank, a filtering device, a gear pump, an oil outlet pipeline, a lifting reversing valve set, an inclined control valve set, a lateral movement control valve set and a distance adjusting control valve set, an oil outlet of the oil tank is connected with the filtering device, an oil outlet of the filtering device is connected with an oil inlet of the gear pump, an oil outlet of the gear pump is connected with an oil inlet of the oil outlet pipeline, and an oil outlet of the oil outlet pipeline is connected with an oil outlet of the distance adjusting control valve set. The oil outlet pipeline is provided with four oil outlets, and the four oil outlets are sequentially connected with an oil inlet of the lifting reversing valve set, an oil inlet of the inclination control valve set, an oil inlet of the lateral movement control valve set and an oil inlet of the distance adjusting control valve set. According to the hydraulic system, the left pallet fork and the right pallet fork can synchronously move leftwards and rightwards as a whole and stretch and retract at the same time, cargoes can move leftwards and rightwards as a whole, flexibility is good, the application range is wide, discharged oil is filtered by arranging the filtering device, and the service life of the hydraulic system is prolonged.

    本发明公开了一种叉车液压系统,涉及叉车技术领域。本发明包括油箱、过滤装置、齿轮泵、出油管路、起升换向阀组、倾斜控制阀组、侧移控制阀组和调距控制阀组,所述油箱的出油口与过滤装置相连,所述过滤装置的出油口与齿轮泵的进油口相连,所述齿轮泵的出油口与出油管路的进油口相连,所述出油管路设置有四个出油口,且四个出油口依次与起升换向阀组的进油口、倾斜控制阀组的进油口、侧移控制阀组的进油口和调距控制阀组的进油口相连。本发明不仅能够使左货叉和右货叉同步实现整体左移、整体右移、同时张开和同时回缩,还能够使货物整体左右移动,灵活性较好,适用范围较广,通过设置过滤装置对排油进行过滤,延长液压系统的使用寿命。
