The thousandth hand-held probe

The HPK was originally developed by DB Systemtechnik in Minden and has been continuously developed and modernized in Kirchmöser ever since. It is used for the non-destructive testing of hollow axles with longitudinal bores - an essential procedure for quality assurance in rail transport. 

The tests are performed manually using ultrasound and take place as part of the maintenance of traction units and wagons. We supply the HPK in 11 different diameter variants so that different bore sizes can be reliably tested. In this way, the test device makes a precise and important contribution to safety in rail traffic. 

Customers from all over the world rely on our testing systems - whether in Mexico City or Saudi Arabia: this piece of German engineering is used everywhere. 

Our Qualitymanagement

For us, Made in Germany not only stands for production in Germany, but also for durability. We recommend sending the HPK to Germany for inspection every two to three years. DB Systemtechnik will carry out testing and maintenance to ensure performance. After a successful inspection, the device is approved for a further two years.

A general overhaul is carried out every 10 to 15 years, during which all wearing parts are replaced. In this way, our HPKs can achieve an impressive service life of 30 to 35 years. 

Ensuring the quality of our test systems is essential for safe rail operations. At the same time, we gain important insights into material wear and construction through regular maintenance. This knowledge is continuously incorporated into the further development of our products. 

For us, the sale of the 1000th hand-held internal search unit is more than just a number - it is a strong sign of quality, reliability and innovative strength. The trust of our customers confirms our approach: continuous further development, durable technology, maximum safety. Together, we are shaping the future of climate-friendly rail transportation.
