Construction-site and on-road use impose different requirements on the frame. That's why we have developed two for the Arocs. One with a narrow frame track of 744 mm, which boasts high torsional flexibility and stability even under extreme off-road conditions and one with a wide 834 mm frame track, which comes into its own in on-road use while also performing convincingly in light off-road use.
For applications focusing primarily on construction-site and off-road use, the narrow frame consisting of cold-worked, high-strength fine-grained steel, measuring 744 mm in width and with longitudinal members measuring 8 or 9 mm in thickness, is employed. This ensures high load capacity and torsional flexibility even in difficult conditions. When the Arocs is used primarily on the road, the 90 mm wider (total width of 834 mm) and more rigidly configured frame of 7 mm or 8 mm in thickness provides for a particularly good combination of attributes such as driving dynamics, torsional flexibility and load-bearing capacity.
