The electrification of road freight traffic with eHighway is an economical alternative to the use of fossil fuels in freight transport. Green, efficient and resource-friendly. eHighway trucks are supplied with electrical energy via overhead lines. An adaptive current collector provides the contact between the vehicle and the overhead line. If the contact with the overhead line is interrupted, for example while overtaking or when traveling on non-electrified routes, the eHighway truck automatically switches over to its diesel-hybrid drive. In operation it is therefore just as flexible and universal as a conventional truck. eHighway offers considerable advantages in particular where rail transport is not possible due to economic or space-related restrictions.
