叉车液压系统一般分为工作液压系统和转向液压系统,工作液压系统组成由工作泵、多路换向阀、限速阀和起升油缸组成,驱动工作装置油缸的往复运动,实现叉车叉取和卸载货物。转向液压系统由转向泵(有时由工作泵代替)、转向器(或负荷传感转向器)和转向油缸组成,驱动行走装置油缸的往复运动, Forklift hydraulic system is generally divided into working hydraulic system and steering hydraulic system, the working hydraulic system consists of working pump, multi-way valve, speed limit valve and lifting cylinder composition, the reciprocating motion of the working device cylinder to achieve forklift fork and Unload the goods. The steering hydraulic system consists of a steering pump (sometimes replaced by a working pump), a steering (or load sensing steering) and a steering cylinder, which drives the reciprocating movement of the traveling cylinder,
