HOWO-TX 8×4 Dump Truck (Model: ZZ3317V386GB1)

The HOWO-TX 8×4 Dump Truck (Model: ZZ3317V386GB1) is a heavy-duty construction truck designed for demanding applications such as construction projects, mining operations, quarry transportation, road construction, and bulk material hauling. With a 400 hp diesel engine, reinforced chassis, dual rear drive axles, and a high-strength T700 steel cargo body, this 8×4 dump truck is built to handle tough working conditions and frequent heavy-load transportation.

Its front-tipping cargo body, robust suspension system, and proven HOWO drivetrain provide a practical combination of power, durability, and operating efficiency for demanding engineering projects.

What Makes the HOWO-TX 8×4 Suitable for Heavy-Duty Work?

Heavy-duty dump trucks operating on construction sites need more than a powerful engine. The chassis, axles, frame, suspension, cargo body, braking system, and tipping mechanism all need to work together under repeated heavy loads.

The HOWO-TX 8×4 uses a reinforced double-layer frame with an 8+8 configuration and a frame width of 300 mm. Reinforced front and rear multi-leaf springs with 11/11/12 leaves provide additional support for demanding transportation conditions.

The 8×4 drivetrain configuration also provides four driven rear wheels across the two rear axles, making the truck suitable for construction environments where road conditions can be difficult.

How Powerful Is the Engine?

The truck is powered by a WP12.400E201 diesel engine rated at 400 hp. This engine provides the power required for transporting heavy loads across construction sites, highways, and other engineering environments.

The engine is equipped with an EVB exhaust brake system, which provides additional braking assistance during downhill driving and heavy-load operation. This can help reduce dependence on the service braking system during certain operating conditions.

The truck uses an engineering-grade air intake system with an oil filter and a standard exhaust system, providing a configuration designed for practical heavy-duty operation.

What Transmission Does the Truck Use?

The HOWO-TX 8×4 is equipped with an HW19712 transmission together with an HW50 direct-coupled PTO.

The 12-speed gearbox provides multiple gear ratios for different operating conditions, allowing the driver to select a suitable gear according to load, road conditions, and vehicle speed.

The direct-coupled PTO can be used to transfer engine power to auxiliary hydraulic equipment, which is particularly important for a dump truck because the hydraulic system needs sufficient power to operate the tipping mechanism.

How Is the Chassis Built for Heavy Loads?

The chassis is reinforced for demanding construction applications. The truck features:

• Reinforced front and rear wheels

• Double-layer frame, 8+8/300 mm

• Reinforced multi-leaf springs

• 11/11/12-leaf spring configuration

• VGD95 front axle with drum brakes

• MCP16ZG dual rear axles with drum brakes

• 5.92 rear-axle gear ratio

• 12.00R20, 18PR mixed-tread tires

This configuration gives the vehicle a strong foundation for heavy material transportation and frequent loading and unloading operations.

The MCP16ZG dual rear axles and 5.92 gear ratio are particularly suited to applications where pulling power and low-speed performance are important.

What Type of Cargo Body Does It Have?

The HOWO-TX 8×4 uses a rectangular cargo box with front tipping. The body is manufactured using high-strength T700 steel, providing increased structural strength for heavy-duty material transportation.

The main cargo body specifications include:

The 8.0 mm T700 steel floor is designed to withstand repeated contact with heavy materials during loading and unloading. The 6.0 mm T700 side panels provide additional structural strength while maintaining a practical dump-body configuration.

How Does the Front-Tipping System Work?

The dump body uses a front-tipping mechanism powered by a Juntong 180 lifting cylinder. During unloading, the hydraulic system raises the front of the cargo body, allowing bulk materials to slide toward the rear and discharge efficiently.

This configuration is commonly used for transporting materials such as sand, gravel, soil, construction debris, and other bulk cargo.

The PTO works together with the hydraulic system to provide the power required for lifting the dump body. Proper operation and regular inspection of the hydraulic system are essential for maintaining reliable tipping performance.

What Is Included in the TX-F Deluxe Cab?

The truck is equipped with the TX-F Deluxe Version cab, which combines practical driver controls with additional convenience features.

Cab equipment includes:

• Multifunctional steering wheel

• Electric and heated rearview mirrors

• Electric cab lifting system

• MP5 multimedia system

• Russian-language instrument panel

• Door lower trim panels

The electric and heated rearview mirrors are particularly useful for operations in colder environments, while the electric cab lifting system provides more convenient access for maintenance and inspection.

A Russian-language instrument panel is also available for markets where Russian is required for vehicle operation.

What Fuel and Safety Equipment Does It Use?

The truck is equipped with a 400-liter aluminum alloy fuel tank, providing a substantial fuel capacity for extended working schedules.

Safety-related equipment includes a 2 kg fire extinguisher and reverse buzzer. The reverse buzzer provides an audible warning when the vehicle is moving backward, which can be useful on busy construction sites and loading areas.

The specified configuration does not include ABS, so buyers should confirm the final vehicle specification and applicable local regulations before placing an order.

Where Can the HOWO-TX 8×4 Dump Truck Be Used?

With its 8×4 drivetrain, reinforced chassis, powerful diesel engine, and high-strength steel dump body, this truck is suitable for a wide range of heavy-duty applications, including:

• Construction material transportation

• Road and bridge projects

• Quarry operations

• Mining support transportation

• Sand and gravel hauling

• Earthmoving projects

• Infrastructure development

• Construction waste transportation

• Large-scale engineering projects

The combination of a 7.6-meter cargo body and high-strength T700 steel construction makes it suitable for projects requiring frequent transportation of heavy bulk materials.

Why Choose a 400 hp 8×4 Dump Truck?

For heavy-duty construction transportation, engine power needs to be matched with the correct axle, transmission, frame, suspension, and cargo-body configuration. A 400 hp engine provides substantial power, while the 8×4 drivetrain distributes traction across the driven axles.

The reinforced frame and multi-leaf suspension are designed for demanding loads, while the T700 steel dump body provides a durable working platform for repeated loading and unloading.

This balanced configuration makes the HOWO-TX 8×4 a practical choice for businesses and contractors looking for a heavy-duty dump truck for demanding engineering operations.
