林口工务段自从一九七六年三月开始试制养路机械液压捣固机,到去年末为止已经制成二十四台,先后在七个养路机械化工区投入使用。全段职工一致认为液压捣固机结构简单,性能良好、效率高、捣固质量好,是发展方向。林口工务段在一九七五年经过七个月的努力奋战,全段基本上实现了以四头电动捣固机为主的养路机械化。大家说,使用电动捣固机把大头镐甩掉了,但它构造复杂、另件多,易发生故障,操纵人员比较紧张。不少同志提出在巩固四头电动捣固机的基础上,我们要更上
Linkou Public Works Section Since March 1976 trial production of road maintenance machinery hydraulic tamping machine, until the end of last year has been made 24 units, has seven road maintenance mechanization area put into use. The whole paragraph of workers unanimously believe that hydraulic tamping machine structure is simple, good performance, high efficiency, tamping good quality, is the development direction. Linkou Public Works section after seven months of hard work in 1975, the whole section basically achieved with four electric tamper-based road maintenance mechanization. Everyone said that the use of electric tampers to pick up the bulk pickaxe, but it is complex in structure, and more pieces, prone to failure, the operator more nervous. Many comrades have proposed that we should be even more on the basis of consolidating the four-headed electric tamping machine
