The Astra HHD9 Tractor is ideal for oversize loads in difficult weather and terrain conditions.
The HHD9 Tractor boasts features that make it a champion of productivity: the high value of the combined total mass enables the use of trailers with high capacities reducing the time of the working cycle.
LOADS UP TO 10 TONS
Loads up to 10 tons thanks to reinforced front drive axles for the most arduous off-road use (routes with steep slopes or heavy loads concentrated on the front of the vehicle).
LOADS UP TO 20 TONS
Loads up to 20 tons for each rear axle with width of 2.9 m, and standard reinforced suspension.
TOTAL COMBINED WEIGHT ABOVE 300 TONS
Total combined weight above 300 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 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.
- 320x90x10 mm 3 assi
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 permits a load of up to 40 tons on the rear tandem.
