The transverse moving range of a tamping device configured by the existing turnout tamping vehicle can meet the requirement of tamping a third rail, but the transverse movement of a tamping unit is completely manually operated, so that the operation efficiency is low, and the tamping operation requirement of a set track line cannot be met; or the third rail can be tamped or even the fourth rail, but a plurality of steel rails cannot be tamped simultaneously (at most two steel rails can be tamped at the same time), the multi-rail tamping operation efficiency is low, and the same sleeper is tamped for a plurality of times and has the risk of damaging the smoothness of the rail.
Thus, there is a critical need in the country or region of stock track availability for an efficient multi-track tamping vehicle solution.
