铁路在我国发展已经有百余年的历史。一百多年以来,铁路养护手段随着铁路事业的整体进步,得到了飞速发展,从纯粹的人力到小型机械化,再到大型机械化,铁路养护手段发展的历史,就是铁路百年史的缩影。铁路养路机械设备的进步,对确保列车安全、平稳、快速运行,保证线路几何尺寸和线路使用状态,延长线路各组成部分的使用寿命起到了重要作用。 The development of railways in our country has been more than one hundred years of history. Over the past hundred years, with the overall progress of railway undertakings, the means of railway maintenance have been rapidly developed. From a purely manpower to small mechanization to large-scale mechanization and the development of railway maintenance means the history of the railway is a microcosm of the centuries-old railway. The improvement of railway maintenance equipment has played an important role in ensuring the safe, smooth and rapid operation of trains, ensuring the geometric dimensions of the railway line and the service status of the railway line, and extending the service life of each component of the railway line.
