Robust in any terrain

    Off-road vehicles must withstand extreme situations. We have an understanding of the special conditions for which our customers build vehicles, and we have therefore been a sought-after partner of many leading manufacturers for years. We are just as reliable as the machines in which our developments can be found. Marquardt has something to offer for every application and for every kind - if in agriculture, on the construction site or for sports and leisure. Complete reliability and an individual, user-friendly design are the guidelines according to which we produce our driving authorization systems, control elements and switching solutions. For us there is no path too rocky.
