Release time:
2024-08-28
Howo has built a comprehensive dump truck lineup tailored to different operational scenarios, spanning light-duty urban transport to heavy-duty mine operations. Core models include the 4x2 10-ton light-duty version, 6x4 30-ton medium-heavy model, and 8x4 40-ton heavy-duty flagship, with total masses ranging from 18,000kg to 49,000kg and curb weights between 7,900kg and 16,800kg. The 4x2 model features a compact 3,800mm wheelbase and overall dimensions of 6,800×2,300×2,550mm, ideal for narrow urban construction sites and short-distance sand-gravel transportation. The 6x4 30-ton model (wheelbase 4,500mm) balances payload and maneuverability, while the 8x4 heavy-duty version (wheelbase 5,800mm, dimensions 9,600×2,550×3,200mm) maximizes load capacity (rated load 32,200kg) for mine and large-scale infrastructure projects. All models comply with Euro V/VI emission standards, equipped with efficient SCR after-treatment systems to meet environmental regulations across urban and suburban operations.

Howo has built a comprehensive dump truck lineup tailored to different operational scenarios, spanning light-duty urban transport to heavy-duty mine operations.

All models comply with Euro V/VI emission standards, equipped with efficient SCR after-treatment systems to meet environmental regulations across urban and suburban operations.
II. High-Power Configuration, Core Strength for Stable Lifting & Loading
The power and lifting systems of Howo dump trucks are engineered for heavy-duty reliability. Flagship heavy-duty models are powered by the MC11.46-60 Euro VI engine, delivering 460 horsepower and 2200N·m of maximum torque, paired with the HW25716XSTC 16-speed manual transmission and AC26 double-reduction drive axles (final drive ratio 4.77). This powertrain ensures strong climbing performance (gradeability ≥ 40%) and stable power output during full-load operations. The hydraulic lifting system adopts a dual-top or front-top design (depending on model) with imported Rexroth hydraulic pumps and cylinders, providing a maximum lifting angle of 60° and fast unloading time (≤ 25 seconds for full lifting, ≤ 15 seconds for lowering). The dump body is crafted from high-strength wear-resistant Q690 steel with a thickness of 14-16mm (floor) and 12mm (side plates), featuring a U-shaped structure to reduce material residue (residue rate ≤ 1.0%). Reinforced frame rails (320×90×8mm) and 12.00R24 radial tires enhance load-bearing stability, supporting heavy loads of ore, construction waste, and bulk materials. The braking system integrates dual-circuit air brakes, WABCO air dryers, and engine exhaust braking, effectively preventing thermal fading during long downhill sections.
III. Scenario-Specific Optimization, Excelling in Complex Working Conditions
Howo dump trucks are tailored to diverse heavy-duty scenarios, delivering exceptional adaptability. For urban construction, the 4x2 light-duty model’s compact size and 11.2m minimum turning radius enable flexible maneuvering in narrow streets and construction zones, while its 180-liter fuel tank balances range and weight. In mine operations, the 8x4 heavy-duty version features reinforced chassis protection, three-stage air filtration, and wear-resistant tires to withstand gravel impact and dusty environments, with a low failure rate even in extreme off-road conditions. For long-distance bulk material transportation (e.g., coal, sand), the 6x4 model’s optimized aerodynamic design and economic speed (65km/h at 1,200rpm) reduce fuel consumption by 10% compared to traditional models. The dump body’s anti-stick coating and streamlined internal structure facilitate smooth unloading of viscous materials (e.g., wet soil), while the adjustable lifting speed control adapts to different material types (granular, bulk, viscous) to prevent spillage.
IV. Innovative Technology Integration, Balancing Efficiency, Safety & Comfort
Technological innovation in Howo dump trucks focuses on three core areas: operational efficiency, safety, and driver comfort. Lightweight design is a key highlight—adopting aluminum alloy components (fuel tank, air reservoirs, transmission case) and high-strength steel frame reduces curb weight by 500-800kg, improving payload capacity and fuel economy. The cab features a four-point suspended mounting system with air suspension seats (heating/ventilation, 10-way adjustability) and noise-insulating interior (≤ 75dB at 60km/h), minimizing driver fatigue during long-hour operations. Advanced safety features include 360° panoramic camera, tire pressure monitoring system (TPMS), and anti-rollover protection (sensors detect abnormal tilting and cut off lifting power). Intelligent controls include a touchscreen display for real-time monitoring of lifting pressure, fuel consumption, and vehicle status, while remote lifting control (optional) enables safe operation from outside the cab. The hydraulic system adopts load-sensitive control technology, automatically adjusting pressure according to load to reduce energy waste.
V. User Reputation Validation, Strengths and Improvement Directions
Market feedback confirms three core advantages of Howo dump trucks: first, robust lifting performance—the hydraulic system and powerful engine ensure stable and fast unloading even with full loads of heavy ore, with no reported lifting failures during continuous 10-hour operations; second, exceptional durability—the reinforced frame and wear-resistant dump body withstand long-term heavy-load use, with most users reporting minimal maintenance needs within 400,000km; third, reliable safety—the anti-rollover system and comprehensive braking protection have earned trust in high-risk mine and mountain road operations. The extensive after-sales network (over 2,500 service stations nationwide) and 24/7 emergency support ensure timely maintenance for uninterrupted project progress.
Users have also suggested areas for improvement: the wear resistance of hydraulic seals could be enhanced for high-intensity long-term use; the cooling efficiency of the hydraulic system needs optimization for high-temperature environments (above 38℃); fuel consumption during idling (e.g., on-site waiting) could be further reduced; and the intelligent control interface could be more user-friendly for older drivers. These insights drive ongoing product upgrades, such as the development of wear-resistant ceramic hydraulic seals and intelligent idle speed control, helping Howo maintain its leading position in the heavy-duty dump truck market.
