This machine is designed to measure the torsion and out of roundness of the railway wheelsets on both the wheels and the brake discs.

The operating principle consists of turning the wheelset by means of rollers in contact with the axle ends. The torsion and out of roundness is measured using a laser meter.

The measuring equipment can be manually adjusted on the X and Y axes and has 3 lasers. Once the arm supporting the machine has been positioned, the following parameters can be measured:


This measuring bench has two supports to fit the wheelset (one fixed and one movable to adapt to different axles), a motor to set the wheelset in rotation, the manually operated measuring equipment and a protective window.

Once the measurement is performed, the machine produces a report that can be printed using a printer previously installed.
