Sitrak C9H 570hp Tractor

Designed and engineered for modern long-haul logistics and cross-region freight transportation, the SITRAK C9H 570HP 6×4 tractor stands as one of the most competitive high-end heavy-duty trucks in the Sinotruk lineup. Rooted in German MAN core technology and optimized for global road conditions, this model balances extreme power, outstanding fuel efficiency, reliable durability, and premium driver comfort, making it one of the most powerful fuel-powered tractors in the entire SITRAK series while maintaining excellent economic performance for daily commercial operation. Unlike conventional heavy trucks that prioritize power at the cost of high fuel consumption or pursue economy with insufficient torque reserve, the C9H 570HP achieves a perfect dual balance, fully meeting the long-distance, high-load, and high-efficiency demands of modern logistics companies.

At the core of its performance is the advanced MC13H.57-61 diesel engine, a 13.02L large-displacement inline six-cylinder power unit adopting international high-pressure common rail fuel injection, turbocharging and intercooling technology. It delivers a maximum power of 570 horsepower and a peak torque of 2600 N·m, with a wide torque plateau ranging from 950 rpm to 1400 rpm. This design ensures sufficient torque output at low speeds, enabling stable starting, smooth climbing, and effortless heavy-load cruising even on mountainous roads and complex terrains. The engine is certified with China VI b emission standards, compliant with mainstream global environmental regulations, ensuring wide adaptability for domestic and overseas transportation scenarios. Meanwhile, optimized combustion calibration and aerodynamic body design effectively reduce overall fuel consumption, bringing significant cost savings for long-cycle fleet operation.

Matching the robust power unit is the mature ZF 12-speed AMT automatic transmission, integrated with an original hydraulic retarder. The transmission features precise gear shifting logic and fast response, eliminating frequent manual operations and reducing driver fatigue during long-distance driving. The integrated hydraulic retarder provides stable and continuous braking force, greatly reducing the wear of service brakes, lowering maintenance costs, and improving driving safety during continuous downhill sections. Cooperated with the high-strength MCY12BGS dual-reduction drive axle and a scientific 2.71 high-efficiency speed ratio, the entire power chain forms a highly matched and efficient transmission system, realizing low-speed high-torque output and high-speed fuel-saving cruising, adapting to both mountain heavy-load transportation and flat highway long-haul scenarios.

In terms of chassis and overall structure, the SITRAK C9H adopts a 270mm high-strength single-layer frame with excellent rigidity and impact resistance, ensuring stable vehicle posture under long-term heavy-load operation and effectively extending the service life of the whole vehicle. The suspension system uses optimized few-leaf spring structure, with optional air suspension configuration, which greatly improves vehicle stability and cargo protection performance. Equipped with 1000L large-capacity aluminum alloy dual fuel tanks (optional 1100L extended version), the truck achieves ultra-long cruising range, effectively reducing frequent refueling stops and improving overall transportation efficiency. The lightweight body design further reduces curb weight, increasing effective load capacity and creating higher economic benefits for fleet users.
