The HÜBNER Group develops and manufactures high-quality upper and lower articulation systems for trams and streetcars. These systems are available both as complete systems in the vehicle gangway and also as standalone components. They securely connect carbodies while providing maximum freedom of movement in curves and stable dynamics during operation.
With HÜBNER’s modular adapter concepts, the articulations can be individually tailored to specific vehicle designs and customer requirements. On request, we also can deliver customized systems that are specifically engineered for a particular vehicle type and project requirements. As always – lightweight, robust and highly durable.
