Performance & Engineering

At the heart of this SINOTRUK HOWO dump truck lies the WEICHAI 6-cylinder inline diesel engine, displacing over 8 liters and producing a peak output of 294kW (approximately 400 horsepower) with maximum torque rated between 1500-2000Nm. This powerplant is meticulously calibrated to deliver robust low-end torque — a critical characteristic for heavy haulage applications where the vehicle must accelerate under full load from standstill, navigate inclined ramps, and maintain momentum on loose or uneven terrain. The engine's EURO 5 compliance ensures adherence to the most stringent current emissions standards, future-proofing the investment for fleet operators in regions with tightening environmental regulations. The fuel system is optimized for diesel efficiency, with the dual-option 400L or 600L fuel tank configuration enabling extended operational ranges of up to 800-1000 kilometers on a single fill, minimizing downtime associated with refueling cycles on remote construction sites.

The FAST 12-speed automatic transmission with 2 reverse gears represents a cornerstone of the vehicle's drivetrain excellence. This heavy-duty gearbox features precisely spaced gear ratios that maximize engine efficiency across the full RPM range, delivering smooth power delivery during gear changes even under fluctuating load conditions. The 8x4 tri-axle drive configuration distributes the engine's 400HP output across four axles, with the forward drive axles providing propulsion while the rear tandem axle set offers additional load-bearing capacity and enhanced stability. The wheelbase measurement of 1800+2575+1400mm translates to an optimal balance between chassis rigidity and maneuverability, making the vehicle well-suited for both confined urban construction zones and open-pit quarry environments. The chassis engineering incorporates high-strength steel construction with reinforced crossmembers and longitudinal rails designed to withstand the torsional stresses inherent to cyclic heavy-load operations.

The vehicle's braking and stability systems deserve particular attention from fleet procurement specialists. The inclusion of ABS (Anti-lock Braking System) and ESC (Electronic Stability Control System) as standard equipment significantly enhances operational safety, particularly when navigating wet or uneven surfaces with a fully loaded 20 cubic meter payload. The air-suspended driver's seat, automatic climate control system, automatic windows, and integrated multimedia entertainment system create a driver environment that reduces fatigue during extended shifts — a factor directly linked to improved safety outcomes and driver retention rates in fleet operations.

Key Advantages & Features

• WEICHAI 400HP Engine with 1500-2000Nm Torque: The 6-cylinder turbocharged diesel powerplant delivers exceptional low-end torque and sustained horsepower across a wide RPM band, enabling the truck to maintain consistent performance under maximum payload conditions. This engine configuration is renowned in the commercial vehicle industry for its fuel efficiency, extended service intervals, and proven reliability in harsh operating environments, making it an ideal choice for demanding construction and quarry applications.
• 20 Cubic Meter Heavy-Duty Cargo Body: The tipper body measures 5.6m in length with a 2.35m width and 1.5m height, providing a nominal capacity of approximately 20 cubic meters. Constructed from high-strength wear-resistant steel, the cargo body is engineered to withstand the abrasive impact of rock, ore, and compacted soil loads. The body geometry is optimized for efficient material discharge, with self-cleaning surfaces and a robust hydraulic lifting mechanism for rapid tip-over cycles.
• Tri-Axle 8x4 Drive Configuration: The three-axle layout with all-wheel drive capability provides superior traction on soft, muddy, or uneven terrain commonly encountered at construction sites. The tri-axle design distributes the gross vehicle weight (≥30T) across a broader contact patch, reducing ground pressure and improving stability during loading, transport, and unloading operations.
• FAST Automatic Transmission with 12 Forward Gears: The 12-speed automatic gearbox from the FAST transmission brand offers seamless gear shifting that maximizes engine efficiency in all driving conditions. This transmission system is widely adopted in China's commercial vehicle sector for its durability, wide gear ratio spread, and ease of operation — reducing driver fatigue and enabling higher average speeds during transport cycles.
• EURO 5 Emission Compliance: Meeting the EURO 5 standard positions this dump truck as an environmentally responsible choice for urban and metropolitan construction projects where emissions regulations are strictly enforced. Fleet operators benefit from regulatory compliance across multiple jurisdictions, reducing the risk of operational restrictions or penalties.
• Advanced Safety Suite (ABS + ESC): Electronic Stability Control works in concert with the Anti-lock Braking System to maintain vehicle control during emergency braking, sharp cornering, or sudden lane-change maneuvers. These systems are particularly valuable for heavy vehicles with high centers of gravity, such as fully loaded dump trucks navigating active construction sites.
• Extended Operational Range (600L Fuel Tank Option): The available 600-liter fuel tank configuration enables extended uninterrupted operations across large construction sites or long-haul quarry routes, minimizing the frequency of refueling stops and maximizing vehicle utilization rates. This capacity advantage translates directly into improved cost-per-ton economics for fleet operators.
• Driver-Focused Cabin with Multimedia System: The air-suspended driver's seat, automatic air conditioning, automatic windows, and integrated multimedia system create an ergonomic and comfortable working environment for operators spending extended hours behind the wheel. The touchscreen interface and rearview camera support (available through multimedia system) enhance situational awareness and operational safety.
