Listen to this everyone!


Train wheelsets need to be inspected regularly, since they have to be absolutely safe. Cracks in the wheels or damaged axles can lead to dangerous accidents.

Listen in to the wheelset material – with Trotec’s LD6000 Combination Detector. The acoustic signals will tell you where there are weaknesses in the material, and you can repair the damage quickly and easily. An inexpensive inspection that you can carry out whenever you wish! Make the most of the cutting edge technology in the LD6000 frequency analysis set. It will ensure that you are always on the safe side with your logistics.

Listen to this everyone!

In early July 2009, an Intercity-Express leaving Cologne’s main railway station suffered a broken axle. It turned out that a wheelset axle had an obvious crack in it. Damaged wheelsets repeatedly cause dangerous situations on the rail network, both for passenger transport and industrial logistics. We read about broken wheels on light railway trains, early fatigue in wheelset material, cracks in axles and wheels. This type of situation does not always have a happy end. Wherever there is a great deal of rail traffic, there is also plenty of danger, even if the wheels have to be replaced regularly. Nobody can get inside a wheelset. But Trotec can now help you to listen inside the material. This is made possible by the LD6000 pipe detector.
You may already know of the LD6000 from its application in leak detection and pipe location. It was for those purposes that this technical all-rounder was developed. And the detector has certainly proven itself in those applications. For example, the LD6000’s acoustic measurements and analyses are used to pinpoint leaks, encircle flaws in pipes, and to locate pipework in general. The high-performance microphone in this frequency analysis set, “made in Germany” of course, is used to record and analyse acoustic signals. And it is precisely this method which is equally well suited to locate cracks and faults in train wheels and wheelsets.

Listen to faults? How does that work?

The frequency analysis makes sound waves audible. And they provide key information about the condition of the material. The LD6000’s vibration sensors record the sound of the material in various places. These frequencies show up on the high resolution colour graphics display. The sound levels at the different measuring points in the wheelset are compared with one another. Differences are looked for. It’s as simple as this: the louder the sound at any measuring position, the greater the probability that there is damage there. Pick up the signs of material fatigue and cracks early on. With the LD6000 combination detector you can prevent worse damage and accidents.
