The JAC K7 540-horsepower 6X4 automatic tractor is a significant offering in the heavy - truck segment, designed with a focus on performance, efficiency, and practicality for logistics distribution. Let's take a closer look at its key features.
The JAC K7 sports a 6X4 drive form, a configuration well - known for its excellent traction and load - handling capabilities. With a wheelbase of 3300 + 1350mm, it provides a stable platform for hauling heavy loads. Measuring 6.94 meters in length, 2.55 meters in width, and 3.85 meters in height, it has a sizeable yet manageable footprint on the road. The front track of 2070mm and rear wheelbase options of 1860/1860 or 1880/1880mm contribute to its overall stability during driving. A minimum turning diameter of 18 meters ensures decent maneuverability in tight spaces, which is crucial for urban and semi - urban logistics operations.
Under the hood, the JAC K7 is powered by the Sinotruk MC13.54 - 50 engine. This 6 - cylinder, inline - arranged diesel engine has a displacement of 12.419L. While it meets the National Five emission standards, its performance is nothing short of impressive. With a maximum horsepower of 540 HP (equivalent to 400kW of maximum output power), it can handle demanding hauling tasks with ease. The engine's maximum torque of 2500N·m, available at a speed range of 1000 - 1400rpm, provides strong pulling power. The rated speed of 1900rpm ensures efficient power delivery across different driving conditions.
The ZF 12TX2621TD gearbox, equipped with AMT (Automated Manual Transmission) technology, is a key component of the JAC K7's powertrain. With 12 forward gears and 2 reverse gears, the AMT system enables smooth and precise gear shifts. This not only enhances driving comfort but also improves fuel efficiency by optimizing gear ratios according to the vehicle's speed and load. The automated shifting reduces driver fatigue, especially during long - distance trips, making it an ideal choice for logistics drivers.
The chassis of the JAC K7 features a frame size of 280×80×8mm, providing a robust structure to support heavy loads. The front axle is a 6.5T unit, while the rear axle is the Fang Sheng 459. The allowable load on the front axle is 7000kg, and on the rear axle (two - axle group) is 18000kg. The rear axle speed ratio of 2.867 is carefully calibrated to balance speed and torque, ensuring efficient power transfer from the engine to the wheels. The vehicle is equipped with 10 tires of the 12R22.5 specification, which offer good grip and durability for various road conditions. The fuel tank, made of aluminum alloy, has a combined capacity of 300 + 600L, providing an extended driving range without frequent refueling stops.
Weighing in at 8.8 tons, with a total mass of 25 tons and a total traction mass of 40 tons, the JAC K7 is built to handle heavy - duty logistics tasks. Its maximum speed of 100km/h is suitable for highway driving, allowing it to keep up with traffic flow while maintaining safety. Designed specifically for logistics distribution, it can efficiently transport goods over long distances, making it a reliable workhorse for the industry.
Originating from Hefei, Anhui, the JAC K7 targets the logistics distribution market. Its combination of a powerful engine, efficient transmission, sturdy chassis, and practical features positions it as a competitive option in the heavy - truck segment. Whether it's for transporting consumer goods, industrial equipment, or other freight, the JAC K7 offers a balance of performance, reliability, and cost - effectiveness. For fleet operators and truck enthusiasts looking for a heavy - duty tractor that can deliver on both power and functionality, the JAC K7 540 - horsepower 6X4 automatic tractor is definitely worth considering.
