The HOWO NX 6x4 tractor is a flagship model developed by China National Heavy Duty Truck Group (CNHTC) for harsh operating scenarios such as mining and infrastructure construction. Equipped with a detachable reinforced cab protective fence, it has undergone multiple safety certifications and performance optimizations to provide all-round protection for transportation operations in complex conditions such as mining equipment transportation, bridge steel component transportation, and infrastructure material transfer, and to provide all-weather protection for heavy-duty transportation.
The powertrain offers a choice of multiple engine series, including MC11 and WP12, with horsepower ranging from 340 to 460. Paired with a 12-speed transmission such as the HW19712, the maximum input torque reaches 2100 Nm, maintaining stable power output even under complex conditions such as mountain climbing and heavy-load starts. When matched with a four-axle flatbed semi-trailer, the vehicle's load capacity reaches 65 tons, easily handling the transportation needs of heavy goods such as bridge steel components and mining equipment.
The vehicle body is assembled from four main components, including protective supports and stiffening assemblies, using 8.8-grade high-strength bolts. Damaged components can be replaced independently, reducing maintenance costs by over 60%. It uses 1.5mm thick high-strength galvanized steel plates, offering superior corrosion resistance compared to similar products in the industry, making it suitable for harsh environments such as rainy and dusty conditions. Multiple cab models are available, including H77L (single sleeper) and H78L (double sleeper, 900mm wide), with a maximum internal height of 1935mm, meeting the needs for long-distance rest. The four-point suspension and air-cushioned seats, combined with wide-angle rearview and lower-view mirrors, balance shock absorption and driving visibility.
Low maintenance costs: The replacement cost of a single protective grille component is only 40% of that of a traditional unibody structure, and the maintenance cycle for core components such as the transmission and drive axle reaches 100,000 kilometers.
