摘要
随着现代文明社会的发展，叉车的使用越来越普遍。叉车主要用途是进行装卸，堆垛和拆垛以及短途的搬动工作。由于叉车具有良好的机动性，又有较强的适用性。适用于货物多，货量大且必须迅速集散和周转的部门使用，因此叉车港口码头，铁路车站，仓库货场几乎不可缺少的机种。由于社会对叉车的需求不断加大，使叉车的性能得到了改善，数目，品种和规格也不断增多，使用范围也不断增多.
随着我国经济建设步伐的加快,各项工程建设也会不断增多，工程建设中也就离不开起重机械。目前起重机的控制系统主要是机械液压控制，随着电液比例控制技术和电子技术在控制系统中的比重越来越大以及它的优越性，电液控制将是主要发展潮流。随着液压元件、微机技术和信息技术的不断发展，智能液压起重机即将出现。那时这种“巨人”可以替代人们做更多的繁重工作，为人类的发展起到无法估计的作用。
关键词：叉车、电液控制、液压元件
Abstract:
Along with the development of modern civilized society, the use of forklift truck is more and more common. The purpose of forklift truck loading and unloading, storage and open and the short form the move work. Because have good mobility, forklift truck and a strong applicability. Apply to more than goods, the volume and must be quickly distribution and the department, so use turnover forklift ports, railway station, warehouse almost indispensable freight model. Because of the social demand for forklift truck increasing, make the performance of the forklift truck improved varieties and specifications, and the number is growing, using range and grow.
As China's economic construction, speed up the pace of the engineering construction will also increase; engineering construction also cannot leave the hoisting machinery. At present the control system is mainly crane mechanical hydraulic control, with electro-hydraulic proportional control technology and electronic technology in control system is more and more big and the proportion of its superiority, the electro-hydraulic control will be the main development trend. Along with the hydraulic components, computer technology and information technology, the development of the intelligent hydraulic crane are coming in. Then the "giant" can replace people do harder work for human development have can't estimate role.
Keywords: forklift、electro-hydraulic control、hydraulic components
