Liebherr to Supply Roll Coupling Components for Combino Low-Floor Trams in Potsdam

Each of the eight trams is being extended from five to seven cars. The hydraulically coupled roll joints were developed in collaboration by Siemens and Liebherr. On uneven or winding tracks, they reduce the stress on the car body structure and the chassis by allowing rotary movements between the cars. A patented circuit configuration automatically corrects misalignments.

Extending the vehicles increases the torsion along their entire length when driving on bends in the tracks. The roll coupling system absorbs torsion in the joints, reducing the stress on the car body structure.
