电动剪刀车的液压系统设计与维修保养 摘要 社会，市场的快速发展促使高空作业车的市场价值得到体现。如何优化剪刀车的设计？如何让延长剪刀车的使用寿命？这些问题越来越受到关注。是否可以解决这些问题对于公司的经济收益而言是非常重要的。“GS?-3246”为研究对象，对该车型的 关键词：高空作业平台，剪刀车，液压，保养 The electric scissors lift hydraulic system design and maintenance Abstract: With the rapid development of economy, China?city construction is advancing by leaps and bounds. Along with the industrial demand, high-altitude operations is more and more. Taking into account the work efficiency and safety, The electric scissors is a special equipment for high-altitude operations, and has become the main force.Its fork type mechanical structure makes the lifting platform lifting has high stability,.wide working platform and high bearing capacity make a greater range of high-altitude operations. Overhead working truck can not only meet the requirements of several people work together, and our work is more efficient and safer of working environment. Its using range is very wide, including electric power, transportation, engineering, construction, building cleaning, garden maintenance etc.Nowadays, the market demand for overhead working truck is bigger and bigger. How to optimize the design of scissors lift? How to prolong the service life of the scissors lift? These issues received more and more attention. How to solve these problems is the key to improve the economic income of the company step. This topic with GS ? - 3246 as the research object, the model of hydraulic system is designed and optimized, and is researched its maintenance at the same time, and form a plan. Make the life of the scissors lift is more and more long, the average cost is reduced. The final purpose is to?let?the value of the car?to improve. To satisfy the requirement of more aerial work, and to improve the economic income for the company. Key words: Aerial work platform, scissors lift ,hydraulic ,maintenance 目录 第1章 前 言 1 1.1高空作业车概括 1 1.1.1剪叉式高空作业车 1 1.1.2直臂式高空作业车 1 1.1.3曲臂式高空作业车 2 1.2国外高空作业车概括 2 1.3国内高空作业车概括 2 1.4电动剪刀车概括 2 第2章 电动剪刀车“GS?-
