About DGS
DGS Diesel- und Getriebeservice GmbH has been based in Mainz-Hechtsheim since 1980 and is the general representative of leading manufacturers of drive units and heavy-duty transmissions for commercial vehicles and industrial applications, including Allison Transmission, MTU, John Deere and Hyundai Infracore. The company sees itself as the link between manufacturer, OEM and end user. In its own Application Engineering department, engineers develop and design customer-specific solutions such as transfer and reverse gearboxes, transmission adaptations, cooling systems, enclosures or accessories such as air compressors and hydraulic pumps; CAD-verified designs are manufactured by specialists. The modernly equipped workshop overhauls complete drive units; engine and transmission test benches allow test runs under load as final inspection. In addition, DGS offers maintenance, on-site repair, spare parts sales with original parts, John Deere Reman exchange engines, training courses in its own facilities as well as warranty processing. Customers are OEMs such as Daimler, Liebherr, Tadano Demag, Manitowoc or Tadano Faun from industries such as crane construction, agriculture, bus and municipal vehicles and oilfield applications.
