820 mm wide, unique heavy duty chassis
Reinforced Frame
Two side members in high resistance special steel with a tensile strength of 530 Mpa with large sections to ensure easy equipment mounting, and most importantly, a high level of torsional stiffness (up to 300 kNm) and high stability in the most extreme situations.
Power Ring
Up to 40 tons on the rear tandem
To increase the robustness and rigidity of the entire structure of the chassis, Astra has patented the power ring: a closed ring structure of the rear suspension, made up of cast iron carriage shoulders and a lower cross member, which improves the redistribution of forces on the tandem.
