铁道道床的捣固是一项工作量较大,强度较高的劳动。长期以来,由于受修正主义路线的干扰,机械化水平一直很低,广大工人仍旧靠一把大镐一双手来养路,远远不能满足运输工作发展的需要。锦州工务段广大工人和技术人员,在段党委的领导和大力支持下,在深入开展“工业学大庆”的群众运动中,大搞养路机械化,于1972年试制成功720型冲击式捣固机和圆筒式捣固机,实践证明,效果良好。现将二种捣固机分别介绍如下:
Tamping iron railroad bed is a heavy workload, high intensity of labor. For a long time, due to the interference of the revisionist line, the level of mechanization has been very low.

Jinzhou Public Works section of the vast number of workers and technical staff, with the leadership and strong support of the party committee in the paragraph, in-depth “Industrial Science Daqing” mass movement, large road mechanization, in 1972 trial success 720 impact tamper and Cylinder tamping machine, proved that the effect is good. Now two tamping machines were introduced as follows:
