SINOTRUK HOWO 8×4 Special Engineering Chassis 420HP

This chassis is equipped with Sinotruk MC11 series 420HP diesel engine, which outputs huge torque at low RPM to deliver sufficient power for climbing and long-distance transport after being fitted with heavy tank or cargo box, balancing strong performance and fuel economy. Mechanical injection engine version is available for overseas markets, without complicated electronic control parts for simple maintenance, and spare parts are widely supplied worldwide, suitable for remote mines and construction sites with poor infrastructure. Matched with HOWO 12-speed high-low range manual transmission, low gears amplify torque for heavy-load startup and steep slopes, while high gears reduce engine RPM to save fuel. The heavy-duty large-diameter clutch avoids slipping and overheating under long-term full-load operation to extend the service life of the whole driveline. The 400L large-capacity aluminum fuel tank greatly extends driving range and reduces frequent refueling during long construction missions.

It adopts mature 8×4 four-axle 12-wheel layout, twin front steering axles plus dual 16-ton HC16 heavy-duty drive axles, with much higher load capacity than 6×4 three-axle chassis and larger legal payload limit. The frame is integrally stamped with double-layer thickened high-strength manganese steel, excellent in anti-torsion and anti-impact performance, without permanent deformation after long-term full-load fitting of superstructures. Widened and thickened multi-leaf heavy-duty spring suspensions deliver outstanding shock absorption on bumpy mine and rural dirt roads to protect upper tanks and equipment. Dual front steering axles provide a large steering angle for flexible turning in narrow factories and construction yards. Standard 12.00R20 deep-tread off-road tires are wear-resistant and puncture-proof for complex road conditions including paved highways and muddy gravel construction sites. Metal protective wire mesh is installed on front headlamps to prevent lamp damage from flying gravel on site, and a yellow warning lamp on the cab roof improves safety visibility during night work. Full air brake system with standard ABS ensures stable braking on downhill heavy loads to avoid skidding and rollover.

Standard mounting brackets and fixing holes are reserved on both sides of the frame without secondary cutting and welding, supporting rapid assembly of various special superstructures: dump cargo box, water/oil storage tank, concrete mixer tank, stake cargo box, truck-mounted crane, road wrecker, sanitation tank and more, with extremely strong modification compatibility. Reserved space on frame sides for air reservoirs, hydraulic pipelines, water pumps and control valves ensures neat pipeline layout and short modification cycle. The frame adopts anti-corrosion painting process to adapt to rainy and windy outdoor overseas environments.

The wide-body single-row HW76 engineering cab offers a spacious interior with shock-absorbing seats to ease driver fatigue during long construction shifts. Oversized split rearview mirrors with wide-angle auxiliary mirrors eliminate all blind zones around the vehicle for higher safety during reversing and turning. The cab features superior dust-proof and noise-isolating sealing, perfectly fitting windy and sandy overseas regions. The dashboard has an intuitive layout displaying real-time core vehicle data including engine speed, oil pressure, air pressure and coolant temperature, with centralized control buttons for easy operation for new drivers. The black roof wind deflector optimizes aerodynamics at high speed to cut fuel consumption, and the bright orange engineering body has high visibility for unified fleet management.

As the core base chassis for overseas special engineering vehicles, this 8×4 universal modification chassis can be customized into multiple special transport vehicles as required: mining dump trucks, 20–30 cubic water/oil tankers, concrete mixers, heavy stake cargo trucks, truck-mounted crane carriers, sanitation washing trucks, etc., to meet all kinds of engineering material transportation demands in one stop. The whole chassis features strong load capacity, stable structure and low failure rate. Customization services cover engine emission standards, fuel tank volume, chassis length and body paint color to comply with road regulations of Africa, the Middle East and Central Asia. Supported by Sinotruk’s global spare parts network, overseas clients enjoy convenient chassis maintenance and parts sourcing, making it the top choice for bulk procurement by modification factories and engineering contractors.
