随着养路机械化的发展,各种液压传动机械日益增加,将要逐步代替电动机械。几年来大批小型液压捣固机投产,已经显示出优质、高效的优越性,深受欢迎。在普及使用液压捣固机中,如何减少机械破损,延长使用寿命和旧件的修复,降低机修费用,则是需要解决的课题。 With the maintenance of road maintenance mechanization, a variety of hydraulic transmission machinery is increasing, will gradually replace the electric machinery. Over the past few years a large number of small hydraulic tamping machine put into operation, has shown the superiority of high quality, high efficiency, very popular. In the popularization of the use of hydraulic tamping machine, how to reduce mechanical damage, extend the service life and repair of old parts, reduce the cost of mechanical repair, it is the problem to be solved.
