Abstract
The invention relates to a machine () having a machine frame (), mobile by means of on-track undercarriages () on rails () of a track grid (), and a stabilizing unit () which comprises a vibration exciter () for generating horizontal vibrations extending transversely to the longitudinal direction of the machine and flanged rollers () designed to roll on the rails (). In this, a camera () is mounted on the machine frame () for recording a section of the track grid () set in vibrations, wherein the camera () is connected to an evaluation device () in order to derive from the recorded image data a resulting deflection (s) of the track grid (). In this manner, the amplitude (a) of the sleeper deflection can be recorded, which is a measure of the actually effective vibration for stabilizing the track.
