Howo V7-X 350HP 8×4 Dump Truck – U-Shape Dump Box

The SINOTRUK HOWO V7-X 350HP 8×4 Dump Truck belongs to the HOWO V7-X series, designed to meet the needs of construction works, ground leveling, material transportation, and mining operations. Let’s explore the all-new exterior and features of this dump truck.

EXTERIOR DESIGN

The HOWO V7-X is the pinnacle of engineering collaboration among three world-leading brands: VOLVO, MAN, and SINOTRUK.
Its low-roof single-sleeper cabin features a sophisticated design, manufactured according to MAN – Germany standards, ensuring refined lines, structural rigidity, and safety during operation.

• Inherited the safety of VOLVO, the cabin offers optimal visibility and a strong structure. The chassis is built with VOLVO technology, featuring the legendary NS07 suspension system: Twin I-Beam Suspension (12-leaf springs), V-rod axle stabilizer, and a wide chassis version. The solid truck frame ensures stability when cornering or carrying heavy loads, providing a balanced driving experience on rough terrains.
• To enhance operational safety, SINOTRUK upgrades the vehicle with a 360-degree camera system. This wide-angle system activates not only when reversing but also when checking the front blind spot of the vehicle—bringing safety to a whole new level.
• The bumper height is raised by 10cm compared to the previous generation, making it more suitable for construction sites. The iron bumper has a very sturdy design. The towing hook is now mounted directly onto the chassis frame, eliminating the risk of the bumper coming loose or breaking off during towing, as seen on older models.
• Rear-view mirrors are designed with a wide viewing angle, and large mirror surfaces offer excellent visibility.
• The front grille now features a more harmonious and robust design, representing the signature look of the new-generation HOWO.
• The headlamp system follows the design of the VOLVO FM-X, equipped with super-bright BI-XENON projector headlights and daytime running LED lights. The front bumper and grille exude a strong VOLVO-inspired appearance.

INTERIOR DESIGN

The interior design inherits the elegance of the VOLVO FM-X. The window control system is now fully integrated into the door panel for better convenience. Both sides feature power-operated windows, electrically adjustable and heated mirrors with four-way adjustment for optimal visibility.

• Smart key system – no more traditional mechanical keys. The windows can be raised or lowered remotely, helping reduce cabin heat before entering during hot days.
• Four-spoke steering wheel with premium aesthetics, integrated multi-function controls, hands-free calling, and cruise control for effortless driving.
• 10.3-inch multimedia display, supports Carbit Link and Bluetooth connection, shows 360° camera view, Wi-Fi connectivity, and multitasking entertainment—unprecedented features for a dump truck.
• Automatic air conditioning with a new rotary design, replacing traditional push-button control.
• Completely redesigned dashboard and cabin trim, providing a spacious, elegant, and refined interior. The overhead lighting system adds a pleasant cabin ambiance at night.
• Additional soundproofing and waterproofing rubber seals have been applied, improving cabin insulation and reducing noise. The engine compartment features a dedicated dust-proof partition.
