Abstract
A tamping device comprises a drive motor which, via a spring mechanism, drives a soil contact element for compacting the soil. A detection device records the speed of rotation of the drive motor. An evaluation device evaluates the dynamic response of the speed of rotation and recognizes an aperiodic response. A control device prompts a change in the speed of rotation of the motor if an aperiodic response has been recognized.
