The invention relates to a fork movement control system of a forklift, which comprises a right fork oil cylinder, a left fork oil cylinder and a mode switching valve group, and is characterized in that the mode switching valve group consists of a throttle valve, a first electromagnetic directional valve, a second electromagnetic directional valve and a third electromagnetic directional valve; the flow direction of fluid can be changed through a first electromagnetic reversing valve, a second electromagnetic reversing valve and a third electromagnetic reversing valve, and single action of a left fork, single action of a right fork, same-direction movement of left and right double forks and reverse movement of the left and right double forks are achieved. The two pallet forks can move independently, move in the same direction at the same time or move in the opposite directions at the same time, and have the advantages of being high in reliability, good in synchronism, good in low-speed performance, small in heat emission and insensitive to oil temperature and load changes.

    本发明涉及一种叉车的货叉移动控制系统,包括右叉油缸、左叉油缸、模式切换阀组,其特征是:所述模式切换阀组由节流阀、第一电磁换向阀、第二电磁换向阀和第三电磁换向阀组成;能够通过第一电磁换向阀、第二电磁换向阀和第三电磁换向阀对流体流向进行改变,实现左叉单动、右叉单动、左右双叉同向移动和左右双叉反向移动;其能够使两个货叉的单独移动,两个货叉同时、同向移动或同时、反向移动,具有可靠性高,同步性好,低速性好,发热少,对油温和负载变化不敏感的特点。
