The Astra HD9 Tractor is used particularly for oversize loads (trailers, half-trailers or dual-use) in the oil and extraction sectors, thanks to its ability to adapt to difficult and adverse weather and terrain conditions.
LOADS UP TO 10 TONS
Thanks to reinforced front drive axles for the most arduous off-road use (routes with slopes or heavy loads concentrated on the front of the vehicle).
LOADS UP TO 20 TONS
For each rear axle with width of 2.5 m, standard reinforced suspension.
TOTAL COMBINED WEIGHT
Above 200 tons depending on the configuration of the vehicle.
820 mm wide, unique heavy duty chassis
Two side members in high resistance special steel with a tensile strength of 530 Mpa with large sections to secure easy equipment mounting and most importantly a high level of torsional stiffness (up to 202 kNm) and high stability in the most extreme situations.
- 320x70x8 mm 2 axles.
- 320x90x10 mm 3 and 4 axles.
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. This enables a load of up to 40 tons on the tandem.
