由我所和成都铁路局什祁养路机械厂等单位联合设计的XYD-2型液压捣固机是一种新的线路捣固机械。1980年经铁道部工务局技术鉴定,决定批量生产,推广使用。它将是我国铁路线路维修机械化的主要设备之一。XYD-2型液压捣固机的机型为单升降油缸双导柱式(图1),其结构合理,布置紧凑,
The XYD-2 hydraulic tamping machine jointly designed by the Institute and the Chengdu Railway Bureau Shifang Road Maintenance Machinery Plant is a new line tamping machine. In 1980, through the technical appraisal of the Ministry of Works of the Ministry of Railways, it was decided to mass produce and promote its use. It will be one of the major equipment for the mechanization of railway line maintenance in China. The model of XYD-2 hydraulic tamping machine is a single lift cylinder double guide column type (Fig. 1). Its structure is reasonable and the layout is compact.
