HowoV7X 380 8×4 Dump Truck – Square Shape Dump Box (8+8)

The HOWO V7X dump truck series is the latest upgraded generation of SINOTRUK HOWO dump trucks. This new generation is jointly developed with three of the world’s leading commercial vehicle manufacturers, integrating the best advantages from each brand: Volvo’s top-level safety standards, MAN’s powerful drivetrain and robust chassis technology, and China’s most advanced commercial vehicle technologies. The vehicle is ideally suited for construction projects, land leveling, building material transportation, mining operations, and other heavy-duty applications.

The chassis system is exceptionally robust, featuring a double-layer 8+8mm chassis frame – one of the strongest in its segment. The cargo body has also been comprehensively upgraded with a stronger structure and enhanced load-carrying capability..

Exterior 

The vehicle features a newly redesigned front grille with a more harmonious, aggressive, and modern appearance compared to previous HOWO dump truck generations in Vietnam. The V7X cabin is the latest upgraded version, inheriting advanced Volvo-inspired cabin safety technology. The cabin structure is finely engineered, rigid, and durable, while the expanded field of vision enhances operational safety for the driver.

Exterior Highlights:

• Heavy-duty steel front bumper specially designed for construction-site operation.
• The bumper height is raised more than 10cm compared to previous-generation dump trucks, improving ground clearance for rough terrain and eliminating concerns about bumper impacts.
• Reinforced towing hook mounted directly onto the chassis frame, preventing bumper damage during towing operations.

To further improve driving safety, SINOTRUK equips the vehicle with an ultra-wide-angle 360-degree camera system – the first factory-installed 360° camera system on HOWO dump trucks in Vietnam. The camera system is integrated into a large 14-inch LCD display, significantly improving operational safety.

• Electrically adjustable 4-way rearview mirrors with heating function
• Electrically tilting cabin with lower-mounted engine start control system
