Abstract
Prior to immersion into the ballast, a hand tamper ( 1 ) for tamping a track is detachably connected to an anchor element ( 10 ), fixed to the track ( 9 ) and lying opposite with regard to a tamping motion ( 18 ), by means of a fixing member ( 15 ) fastened to a tamper section ( 6 ) situated between a drive motor ( 3 ) and a tamping blade ( 5 ). Thus, an improved compaction effect can be achieved.
Claims
exact text as granted — not AI-modified1 . A method of tamping a track by immersing a hand tamper into ballast, wherein prior to the immersion into the ballast, the hand tamper is detachably connected to an anchor element, fixed to the track and lying opposite with regard to a tamping motion, by means of a fixing member fastened to a tamper section situated between a drive motor and a tamping blade.
2 . The method according to claim 1 , wherein two hand tampers, each serving as an anchor element, are used for tamping, the tampers being connected to one another by means of the fixing member and plunging into the ballast at the same time at an opposite longitudinal side of a sleeper, respectively, with regard to a tamping movement.
3 . The method according to claim 1 , wherein a rail anchor detachably connected to the rails is used as an anchor element.
4 . A The method according to claim 3 , wherein the anchor element is fastened at an intersection of the sleeper and the rail.
