Inspection of axles in light maintenance

The axles of trains must be inspected regularly for signs of fatigue caused by dynamic loads and external influences using ultrasound. In light maintenance, this is done with the SHUTTLE system directly on the train from the longitudinal bore of the axle. This enables a reliable evaluation of the axle condition with minimum downtimes. The SHUTTLE system can be optimally adapted to the local conditions of the depot.
