Heavy-duty truck HD9

3-axlefor mining applicationsconstruction

The HD9 tractor stands out for the strength and reliability it guarantees in off-road conditions. It is used particularly for oversize loads (trailers, half-trailers or dual-use) in the oil and extraction sectors, thanks its ability to adapt to difficult and adverse weather and terrain conditions, from the heat of the African deserts to the ice of Alaska. Available in a 2 or 3-axle and tridem version, it offers a combined total weight above 200 tons. PRODUCTIVITY The HD9 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. Its robustness ensures it is reliable. The simplicity of its mechanical and electronic structure limits maintenance time and costs. 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 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 "C-section" with flat, parallel elements to ensure easy configuration POWER RING 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
