Optimum framework conditions for off-road assignments. Based on the straight frame of the Actros construction vehicle, a robust and durable ladder-type frame with open C-section longitudinal members and bolted C-section transversal members was designed. Interior reinforcements ensure maximum load-bearing capability. The frame is torsionally flexible with 2 x 500 mm axle articulation (diagonal). The frame head was also designed to enable attachment of equipment, and for towing or lifting the vehicle. And the frame concept enables a high degree of flexibility for mounting body assemblies.
