Abstract (en)
[origin: WO2020057865A1] The invention relates to a tamping unit (1) for tamping material under sleepers (5) of a track, having a tool carrier (6) which is mounted on a unit frame (2) such that it can be lowered and on which two pivot levers (11) with tamping tools (15) are mounted rotatably about respective pivot axes (12) such that they can be adjusted relative to each other and such that a vibration can be applied to them, wherein at least one pivot lever (11) is assigned a sensor (16) for sensing a pivot angle of a pivot movement (21) about the associated pivot axis (12). The sensor (16) is constructed from a number of parts, wherein a first sensor part (18) is fastened to the tool carrier (6), and a second sensor part (19) is fastened to the pivot lever (11).
