目前线路维修主要用三种类型的枕木捣固机械,即:手提电动捣固机、四头电动捣固机以及小型液压捣固车。这三种捣固机械虽已逐步在全路推广使用,但都还在不同程度上存在一些缺陷,有待改进。手提电动捣固机(以下简称电镐)是三类捣固机械中数量最多,使用最广的机械。据不完全统计,现在全路共有各式电镐不下两万台,它是机械化捣固作业的主要机具。由于设计、制造和使用上的原因,目前所用电镐在结构、性能、效率或作业质量上都还有一定的
Currently, there are three main types of sleeper tamping machines used for line maintenance, namely: electric tamping machine, four electric tamping machine and small hydraulic tamping car. Although these three types of tamping machines have been popularized and used all over the country, they still have some defects in varying degrees and need to be improved. Portable electric tamping machine (hereinafter referred to as electric ho) is the largest number of the three types of tamping machinery, the most widely used machinery. According to incomplete statistics, there are now a total of 20,000 electric picks all over the country. It is the main tool for mechanized tamping operations. Due to the design, manufacture and use of the reason, the current electric pick in the structure, performance, efficiency or quality of work there is a certain
