根据铺轨工作现代化的需要,铁道部第三工程局结合长期铺轨实践,经过一年的时间,设计了一台铺轨机。 设计完成后,在全局范围内组织力量,由三个单位分别承担结构、机械和电气部分的试制,于1978年7月中旬全机组装完成。制成以后,作了一般负荷、超负荷和远距离的挂运试验,后又作了局部改进。 “长征一号”铺轨机于同年8月10日在东陇海复线上正式使用,铺轨进度不断提高,每个台班可稳产
According to the needs of modernization of track laying work, the Third Engineering Bureau of the Ministry of Railways, in combination with long-term track laying practices, designed a track laying machine over the course of a year. After the design was completed, it organized forces in a global scale. Three units undertook the trial production of the structure, machinery and electrical parts respectively and completed the assembly in mid-July 1978. After made, made a general load, overload and long-distance hang-up test, and later made a partial improvement. The “Long March No. 1” track laying machine was officially used on the East Longhai Double Line on August 10 of the same year, and the track laying progress was continuously improved.
