Howo V7-X 400HP 8×4 Dump Truck – Square-Shape Dump Box (8+8 mm Chassis)

The HOWO V7-X 400HP 8×4 Dump Truck – Square-Shape Dump Box (8+8 mm Chassis) is part of the HOWO product lineup and represents SINOTRUK’s latest upgraded generation of dump trucks. This generation was developed through the collaboration of three of the world’s leading truck manufacturers, combining the best strengths of each: the highest safety standards from Volvo, the strongest drivetrain and most robust chassis from MAN, and the most advanced technology equipment from China.

The vehicle is ideally suited for construction projects, land leveling operations, building material transportation, mining activities, and other heavy-duty applications.

Its chassis system is among the strongest in its segment, featuring a double-layer 8+8 mm chassis structure. The dump box has also been significantly upgraded with a stronger and more robust design, offering multiple advantages that increase the truck’s load-carrying capacity.

EXTERIOR DESIGN

The truck features a harmoniously redesigned front grille, giving it a more modern, stronger, and more attractive appearance compared to previous HOWO dump truck models in the Vietnamese market. The V7-X cabin is the latest upgraded version, inheriting many features and designs based on VOLVO cabin safety technology. The cabin is finely crafted, solid, and durable. Visibility has been improved, providing greater safety for the driver during operation.

Exterior highlights include:

• The sturdy iron bumper assembly is highly suitable for construction applications. The bumper height has been raised by more than 10 cm compared to older dump truck generations, making it better suited for construction environments. Scraping the bumper is no longer a major concern, and the iron bumper is designed for exceptional durability.
• The towing hook has been improved and mounted directly to the front of the chassis frame, eliminating concerns about the bumper being damaged during towing, as seen in older models.
• To enhance operational safety, SINOTRUK has upgraded the vehicle with a four-camera system featuring an ultra-wide viewing angle. This is the first HOWO dump truck model in Vietnam equipped with a four-camera system, taking safety to the next level. The factory-installed four-camera system is integrated into a large 14-inch LCD.
• Electrically adjustable four-way rearview mirrors with heating function.
• Electrical tilting cabin with an engine start control unit located underneath.
• Daytime running lights use LED technology; turn signals, fog lights, and marker lights use HALOGEN bulbs; low and high beam headlights use BI-XENON technology.

INTERIOR DESIGN

The spacious cabin features dark tones combined with chrome accents arranged scientifically, complemented by modern patterns on the fabric ceiling and sleeper bed, creating a luxurious and elegant interior.

• Smart-key system replaces the traditional mechanical key. Simply stand outside and press and hold the button, and the windows will automatically go up or down, helping reduce the intense heat when entering the cabin on sunny days.
• Stylish four-spoke steering wheel with multifunction controls for the display, hands-free calling, and convenient cruise control operation.
• LCD display connects to smartphones via Carbit Link and Bluetooth, displays the four-camera system, supports multitasking and Wi-Fi connectivity—never before has driving a dump truck been this entertaining.
• Beautifully designed automatic air conditioning with convenient rotary controls—no more pressing buttons, now you just turn and adjust.
• Additional soundproof and waterproof seals help reduce cabin noise and improve insulation. An engine dust barrier is also included.
• The low-roof V7X cabin features a 700 mm wide sleeper bed. The cabin also includes an integrated storage compartment beneath the sleeper, using lightweight and user-friendly materials that help reduce noise.
• The driver’s seat is an air suspension seat with multiple adjustment modes, upgraded materials, and premium patterns. It also features an automatic seat height adjustment function.
• The passenger seat is a standard seat but is also made from high-quality materials..

CHASSIS

• The chassis is larger and thicker, clearly outperforming other products on the market. While other trucks only use dual-layer chassis configurations of 8+5 mm or 8+4 mm, the V7X 8×4 uses a dual-layer 8+8 mm chassis. Combined with a width of up to 300 mm, it offers outstanding strength and stability.
• The truck is also equipped with a V-shaped axle brace, a familiar design in the Vietnamese market that ensures more stable chassis performance and reduces side-to-side vibration differences. Together with the dump box stabilizing system and cabin stabilizing structure, it significantly improves lateral stability.

Other Specifications

The Howo V7X 400 8×4 Dump Truck – Square-Shape Dump Box is equipped with an additional wet air filter for the intake system before air enters the engine. This filter provides several benefits for both engine performance and the environment:

• Improved engine performance: Protects the engine from impurities in the air, improves fuel-air mixing, increases air injection pressure into the cylinders, enhances combustion efficiency, and boosts engine thermal efficiency and output.
• Reduced fuel consumption and lower noise: Better intake air quality creates a more efficient fuel-air mixture, reducing fuel consumption and minimizing knocking, noise, and vibration.
• Environmental protection: Improved combustion efficiency helps burn fuel more completely, reducing CO and PM emissions.

The V7X dump truck also features an integrated PTO system mounted directly to the gearbox. This design provides longer service life, fewer components, less risk of failure, and lower maintenance requirements compared to conventional PTO systems.
