High-Power SINOTRUK HOWO 6x4 Tractor Truck (Trailer) — For Construction Engineering

High-Power SINOTRUK HOWO 6x4 Tractor Truck for Construction Engineering

Equipped with high-power engines—either from Weichai or independently developed by SINOTRUK—this vehicle offers a maximum power output ranging from 400 to 580 horsepower. Compliant with China's National VI emission standards, it ensures robust power delivery even under complex operating conditions, such as heavy-load hauling and steep-grade climbing. The powertrain is paired with a SINOTRUK 12-speed or 16-speed manual transmission; featuring a low first-gear ratio of 14.941 and a maximum input torque of 2500 N·m, it works in conjunction with third-generation MAN-technology axles to achieve a transmission efficiency of up to 98.6%. Furthermore, the rear axle boasts an extended maintenance interval of up to 240,000 kilometers, significantly reducing maintenance costs.

Chassis and Load-Bearing Capacity

The vehicle utilizes a flexible, high-strength frame based on MAN TGA technology. Combined with a "2-leaf front / 2 or 3-leaf rear" suspension design, the chassis strikes an optimal balance between lightweight construction and load-bearing performance. The front axle features an allowable load of 7 tons, while the rear axle supports an allowable load of 18 tons. Fitted with 12R22.5 tubeless tires and supporting a 10-wheel configuration, the truck ensures stable and reliable transport of construction materials—such as sand, gravel, and concrete—even across challenging terrain. A dual-fuel tank design (comprising an 860L main tank and a 200L auxiliary tank) further extends the vehicle's cruising range, effectively meeting the operational demands of remote construction sites.

Cab and Comfort

The cab features an integral cage-structure frame with sheet metal plating up to 1.5 mm thick, mounted on a four-point full-floating suspension system that effectively dampens road vibrations. The driver's seat is an air-suspension model upholstered in leather, offering multi-directional adjustment capabilities and lumbar support. The sleeper bunk measures 90 centimeters in width and is fitted with a thick mattress, providing the driver with a comfortable environment for rest and recuperation. Thanks to optimized NVH (Noise, Vibration, and Harshness) performance, interior noise levels at idle remain below 52 decibels, thereby reducing driver fatigue during long-haul operations.

This high-power SINOTRUK HOWO model is widely utilized in the construction engineering sector for material transport—specifically for the heavy-duty hauling of goods such as sand, gravel, concrete, and steel. With its high-power drivetrain, robust load-bearing chassis, and ergonomically designed cab, the vehicle significantly enhances transport efficiency while simultaneously lowering total lifecycle operating costs, making it the ideal choice for construction industry professionals.
