摘要  自行式液压升降车是将剪叉式的升降台放在由两个液压马达驱动的小车上，担负生产车间中中物料的运输、储存、装卸物料等任务，以便节省人的体力劳动，节约时间，提高加工效率。
　　　自行式液压升降车主要由行走系统，电气控制系统和液压控制系统三部分组成。将小车底盘作为工作台，液压马达和液压系统都安装在上面，由接触器-继电器来控制电动机和电磁阀，从而控制液压马达的转速和液压缸的活塞速度，以实现规定的动作，即：液压泵驱动两个液压马达和一个液压缸以实现车轮的转动和液压缸的伸缩。由于这几个机构不是同时工作，泵的最大流量由这几个机构中流量最大的机构所决定。

Title  Self-propelled hydraulic lift truck design
Abstract
Self-propelled hydraulic lift truck that put scissors-type lifting platform on the car is driven by two hydraulic motors, and take in the workshop materials in transport, storage, loading and unloading of materials and so on. It is to save people's physical labor, save time and improve processing efficiency.
Self-propelled hydraulic lift truck mainly by running the system, electrical control system and hydraulic control system composed of three parts. The car chassis as a table, hydraulic motors and hydraulic systems are installed in the top of it. The contactors and relays control hydraulic motor and solenoid valve to control the rotational speed of hydraulic motors and hydraulic cylinder piston to achieve the required action. That is, hydraulic pump drive two hydraulic motors and a hydraulic cylinder to achieve the rotation of the wheel and telescopic hydraulic cylinder. Since the work of these bodies are not the same time, the maximum pump flow of by these agencies determine by the largest bodies.
