Abstract
A tamping unit for tamping sleepers of a track includes a tool carrier supported in a lowerable manner on an assembly frame, on which two pivot levers with tamping tools are mounted so as to be squeezable toward one another and, while being actuatable with a vibration, are rotatable about a respective rotation axis. A sensor for recording a pivot angle of a pivoting motion about the related rotation axis is associated with at least one pivot lever. The sensor has a multipart configuration with a first sensor part fastened to the tool carrier and a second sensor part fastened to the pivot lever. In this manner, sensitive sensor components in the first sensor part are subjected to lessened stress since the tool carrier merely performs a lowering or lifting motion during a tamping operation. A method for operating the tamping unit is also provided.
