It is also possible that it extends along the compartment.

The measuring device 17 is arranged along this guide 16 and thus parallel to the track 8 to the tire 9 arranged on the surface of the carrier 10 and/or to the power transmission mechanism 14. However, it is preferable that the measuring device 17 is automatically displaced. For that purpose, the measuring device 17 is supported in the guide 16 via the roller 18 and is attached to the measuring device 17 to act on the measuring device 17 as shown in the drawings. It may be displaced or moved along the guide 16 by a driving device arranged on the surface of the device or incorporated in the measuring device 17.

The measuring device 17 comprises at least one sensor for detecting characteristics, in particular geometrical and/or vibrational characteristics, of the power transmission mechanism 14 or of individual components of the power transmission mechanism 14, for example the drive wheels 12 or the drive means 13. 19, in particular having an optical sensor.
