Sinotruk chassis: 3 million kilometers of verification, how to become the "steel backbone" of engineering transportation?
date:2025-06-20
"Bumpy roads in mining areas, cracked frames; overloaded slag, broken bridges..." In the life-and-death battlefield of special vehicles, the reliability of the chassis directly determines the operating cost. Sinotruk reshapes the benchmark of special vehicle chassis with MAN technology genes + localized innovation.
Three hard-core genes of Howo chassis
1. Armor-level protection: frame and materials
HowoTX mining version uses 700MPa high-strength alloy steel: the yield strength exceeds the industry standard by 15%, and the thickness of the longitudinal beam reaches 10mm.
Local double-layer reinforcement: Strengthen the stress concentration areas such as the lifting fulcrum of the dump truck, and the Sinotruk patented riveting process improves torsion resistance.
2. Golden match of power chain
Howo dump truck exclusive solution: MC13 540 horsepower + Fast 16 gears + ST16 two-stage reduction bridge (speed ratio 6.5) → Shanxi customers measured a 40% increase in climbing torque.
Sinotruk tractor efficient combination: MCY13 single-stage bridge (speed ratio 2.85) + Sinotruk AMT → cold chain fleet fuel consumption per 100 kilometers as low as 28L.
3. Scenario-based suspension system
Howo engineering version: split balance shaft + engineering tire, suitable for 50-ton overload conditions.
Sinotruk logistics version: air suspension + lightweight design, 8% reduction in deadweight.
Real scene conquest record
Case 1: "Armored Chariot" in Inner Mongolia mining area
Challenge: 50°C temperature difference + gravel hitting.
HowoTX 8×4 chassis solution: AC16 wheel-side reduction bridge + titanium alloy protective cover, maintenance costs reduced by 35%.
Case 2: Yangtze River Delta Cold Chain Fleet
Sinotruk Sitrak C9H 4×2 chassis: MCY11 lightweight bridge (weight 7.2 tons) + intelligent cruise, single trip fuel saving 180L.
The future has come: the direction of technological evolution
Sinotruk electric drive chassis: MCY13E electric drive bridge mass production (endurance 500km).
Howo hydrogen heavy truck: demonstration operation in 2024, adapted to municipal vehicles.
Conclusion
"What is carried is weight, what is delivered is value." Howo & Sinotruk dual-brand chassis, based on reliability and scenario as the measure, is becoming an invisible engine for logistics cost reduction.
