SiemenseHighway for electric trucks in Germany
Siemens was commissioned by the state of Hesse to build an overhead line system for an electrified road freight transport system on a 10 km route. The overhead line will supply the electric drive of a hybrid truck with electricity.
In the follow-up project Enuba 2, Siemens entered into a partnership with the Swedish company Scania. The focus is on the optimized integration of drive technology and pantographs into the vehicle as well as the provision of the necessary traffic control systems. To this end, an extended test track was put into operation in Groß Dölln, north of Berlin, which is adapted to the conditions of real operation. The route was given a curve that can be negotiated at speeds of up to 90 km/h with an overhead line adapted to the curve. A sign gantry and cantilever arm with traffic signs, which are common on long-distance roads, were also installed. Because the overhead line has to be installed at a safe distance below the traffic signs, the catenary and suspension cable were lowered so that the pantograph can maintain contact throughout, even at full speed.
