Der Muldenkipper MK-A20Ex der GHH Fahrzeuge ist in Übereinstimmung mit der ATEX-Richtlinie speziell für den Einsatz in explosionsgefährdeten Bereichen konstruiert und basiert auf dem bewährten MK-A20. Das neu überarbeitete Fahrzeug mit wassergekühltem Motor erfüllt höchste Ansprüche an Ergonomie und Wartungsfreundlichkeit. Die Maschine zeichnet sich durch einen robusten und einfachen Aufbau aus und ermöglicht somit geringste Betriebskosten bei sehr hoher Förderleistung. Der MK-A20Ex kann optimal mit einem LF-10Ex kombiniert werden.
