The HOWO 8×4 dump truck, a heavy-duty dump truck manufactured by Sinotruk, is widely used in construction, mining and other fields. Below is a detailed introduction:
Appearance
-
Cab: Most adopt the HW76 cab, which is spacious and comfortable, featuring an integrated sleeper for rest during long-distance transportation. Some models are equipped with a galvanized bumper that has good corrosion resistance and can effectively protect the front of the vehicle from collisions.
-
Body Design: The body adopts an aerodynamic design, reducing wind resistance during driving and improving fuel efficiency. The overall appearance is robust and well-structured, reflecting the characteristics of a heavy-duty truck.
Chassis and Axles
-
Chassis Frame: Utilizes a U-shaped parallel ladder frame with dimensions of 300x80x8mm, reinforced with cold-riveted cross members. This provides high strength and reliability, capable of withstanding significant loads and bumpy road conditions.
-
Front and Rear Axles: The front axle is typically the VGD95 model with a load capacity of 2x9,000kg, featuring a double T-section beam for steering. The rear axle is the HC16 model with a load capacity of 2x16,000kg, using a pressed axle housing, central single reduction with hub reduction, and differential locks between wheels and axles. This ensures strong load capacity and good stability.
Power System
-
Engine: Equipped with SINOTRUK's efficient diesel engines, such as the WD615.47 engine with 371hp or the WP12.400 engine with 400hp. These engines feature six cylinders in-line, water cooling, turbocharging, and intercooling. They deliver strong power, reliable performance, and good fuel efficiency while meeting Euro II emission standards.
-
Transmission: Generally uses the HW19710 transmission, offering 10 forward gears and 2 reverse gears. This provides a wide range of gear ratios to meet different driving conditions and hauling requirements. Some models also come with a power take-off (PTO) function, enabling the vehicle to power other equipment.
Suspension and Braking System
-
Suspension System: The front suspension consists of 10 semi-elliptical leaf springs, hydraulic telescopic double-acting shock absorbers, and stabilizers. The rear suspension uses 12 semi-elliptical leaf springs, bogie springs, and stabilizers. This configuration provides strong load capacity and good shock absorption, ensuring comfortable driving on bumpy roads.
-
Braking System: Features a dual-circuit compressed air braking system for service brakes, with spring energy and compressed air operation on the front axle and rear wheels for parking (emergency) brakes. An auxiliary engine exhaust brake is also included. This ensures reliable braking performance and high safety during driving.
Cargo Box
The cargo box dimensions vary across models, such as 6,800x2,300x1,500mm or 7,000x2,300x1,750mm, with a capacity of 28-32 cubic meters. The box floor is made of 8mm-thick steel plate, and the sides are made of 6mm-thick steel plate. It features a front lifting system operated by hydraulic rams, enabling smooth unloading of materials like sand, gravel, and coal at the destination.
Electrical System
Operates on a 24V voltage system with negative grounding. It includes a 24V, 5.4kW starter, a three-phase 28V, 1500W alternator, and 2x12V, 165Ah batteries. The vehicle is equipped with standard electrical features such as a cigar lighter, horn, headlights, fog lights, brake lights, indicators, and reverse lights, meeting daily usage requirements.
Other Features
-
Steering System: Equipped with ZF power steering, model ZF8118, featuring hydraulic steering with power assistance. This ensures light and flexible steering, reducing driver fatigue.
-
Tires: Typically uses 12.00R20 radial tires, with some models offering optional 315/80R22.5 or 12R22.5 tires. These tires provide good grip and wear resistance, ensuring driving safety on various road conditions.
-
Fuel Tank: Features a 300L fuel tank, meeting long-distance transportation needs and reducing refueling frequency. | Product name | 8*4 dump truck |
