The ROMER Absolute Arm measuring device ensures the highest quality of modern trams

With this system the measurement time was reduced by half. Currently, every week one new tram leaves the Poznan plant. It would be impossible without the Hexagon Metrology solution. Marcin Wojciechowski, Quality Control Manager, confirms that “without the arm, a number of measurements would be impossible to make, while others would be made very difficult”.

It is used to measure the two tram body areas; one is the connection of the body with the bogie and the second is the body articulation joints. The operators make measurements quickly and comfortably. The...
