The HOWO 8x4 Dump Truck is a heavy-duty vehicle produced by Sinotruk (China National Heavy Duty Truck Group Co., Ltd.), designed for transporting large volumes of materials in construction, mining, and other industries. The 8x4 configuration indicates that the truck has eight wheels, with four of them powered by the engine, which allows for a higher payload capacity and better stability compared to 6x4 trucks.

Key Features and Specifications of the HOWO 8x4 Dump Truck:

1. Configuration:

• 8x4 Drive System: Eight wheels, with power distributed to four of them. This setup provides enhanced stability and load distribution, making it ideal for heavy-duty, high-volume transportation.
• Chassis: Built with a robust chassis for handling heavier loads over rough terrains, suitable for challenging working conditions like mining sites and large construction projects.

2. Engine:

• Engine Type: Diesel-powered, usually equipped with Sinotruk’s WD615 or similar engine.
• Power Output: Typically 336 hp to 420 hp, depending on the specific model and configuration.
• Torque: High torque output, often in the range of 1,500 to 1,870 Nm, providing the truck with the ability to handle heavy loads and tough terrain.
• Emission Standards: Complies with Euro II, III, IV, or higher, depending on the region and configuration.

3. Transmission:

• Transmission Type: Manual transmission with 10 to 12-speed gearbox options, such as the HW19710 or HW19712.
• Transmission Performance: Ensures smooth power delivery for the engine to the wheels, designed to handle the high torque and load demands of heavy-duty tasks.

4. Payload Capacity:

• Payload Capacity: Ranges from 30 to 45 tons, depending on the specific model and regional regulations. The 8x4 configuration provides increased stability and capacity compared to 6x4 trucks.
• This truck is ideal for carrying large amounts of material, such as sand, gravel, stones, coal, or debris in construction and mining environments.

5. Dump Bed:

• Body Volume: Typically ranges from 20 to 30 cubic meters, allowing for large volumes of loose material to be transported in one trip.
• Material: Made from reinforced steel to withstand heavy and abrasive loads.
• Tipping Mechanism: Equipped with a hydraulic system that tilts the dump bed from the front, allowing materials to be unloaded from the rear.

6. Axles and Suspension:

• Axles: Comes with four axles, two of which are powered to provide better traction and load distribution. Typically fitted with 16T heavy-duty rear axles for enhanced carrying capacity.
• Suspension: Leaf spring suspension designed to handle heavy loads while maintaining stability and comfort over rough or uneven terrain.

7. Tires:

• Tire Type: Commonly equipped with 12.00R20 or 13.00R25 tires, providing strong grip and durability for off-road and on-road use.
• These tires are designed to handle the weight and stress of transporting large payloads in various terrains.

8. Dimensions and Weight:

• Overall Length: Typically around 9.6 to 10 meters (31.5 to 32.8 feet), depending on the specific model and configuration.
• Width: Around 2.5 meters (8.2 feet).
• Height: Around 3.45 meters (11.3 feet).
• Curb Weight: Approximately 15,000 to 18,000 kg (33,000 to 39,700 lbs).
• Gross Vehicle Weight (GVW): Typically ranges between 38,000 to 45,000 kg (83,775 to 99,208 lbs).

9. Braking System:

• Service Brakes: Uses an air brake system with drum brakes on all wheels, offering strong braking performance under heavy loads.
• Parking Brake: Mechanical brake acting on the rear wheels for secure stopping.
• Some models may include ABS (Anti-lock Braking System) for enhanced control and safety during braking.

10. Cabin:

• Design: The cabin is designed for operator comfort, featuring a spacious layout with ergonomic controls.
• Seating: Often equipped with an air-suspended, adjustable driver’s seat for comfort during long shifts.
• Visibility: Large windows and strategically placed mirrors to ensure good visibility, crucial for safety in work zones.
• Safety Features: Includes seat belts, overhead protection, and safety locks. Some models also come with an optional System of Active Stability (SAS) to enhance safety during operation.

Applications:

• Construction: Transporting large volumes of materials such as sand, gravel, and asphalt for road building and infrastructure projects.
• Mining: Hauling heavy loads of ore, coal, or waste materials from mining sites to processing plants or stockpiles.
• Infrastructure Development: Used in large-scale projects like bridge building, highway construction, and other major infrastructure projects requiring the movement of massive amounts of material.
• Demolition: Carrying debris, concrete, and other waste material from demolition sites to recycling or disposal areas.

Advantages of the HOWO 8x4 Dump Truck:

• High Load Capacity: The 8x4 configuration allows for a much larger payload compared to smaller dump trucks, making it efficient for transporting large volumes of material in fewer trips.
• Durability: Built to withstand the rigors of heavy-duty work environments such as construction sites and quarries, with reinforced components and a robust hydraulic system.
• Versatility: Suitable for a variety of tasks, from construction to mining and infrastructure projects.
• Cost Efficiency: HOWO trucks are known for their relatively lower cost while maintaining good performance and reliability, making them a cost-effective solution for businesses requiring heavy-duty vehicles.

Common Variants:

• HOWO 336: A model with a 336 hp engine, suitable for medium to heavy-duty transport tasks.
• HOWO 371: A 371 hp variant that is more powerful, often used in more demanding work environments like mining or large construction sites.
• HOWO 420: The highest power option, with a 420 hp engine, ideal for extremely heavy loads and tough terrain.
