Optimum frame conditions for off-road assignments. Based on the Actros Bau straight frame, a sturdy, durable ladder-type frame with open C-section longitudinal members and bolted C-section transversal members was designed. Inner reinforcements ensure maximum load-bearing capability. The frame front end, too, was redesigned to enable attachment of equipment for towing or lifting the vehicle. In addition, the frame concept enables a high degree of flexibility for implement attachment.
