YD-22 II Hydraulic Gasoline Tamping Machine The YD-22 II hydraulic gasoline tamping machine is an updated product developed using new materials and technologies. It can be used for tamping operations on ballasted tracks of type II and III concrete sleepers in China, as well as on various ballasted tracks of concrete sleepers and steel sleepers in foreign countries. This machine is manufactured with a standard gauge of 1435mm and a single side lower track frame. The main technical performance is higher than that of old-fashioned tamping machines. This machine is suitable for tamping operations after large and medium maintenance and screening operations on different types of steel rails and concrete sleeper tracks; It is also suitable for the tamping operation of ballast on newly built track beds. This machine has superior performance, reasonable structure, safety and reliability, high operating efficiency, and fully meets the needs of railway ballast compaction operations.
