SINOTRUK chassis: 3 million kilometers of verification, how to become the "steel backbone of engineering transportation?"

"The bumpy road in the mining area causes cracks in the vehicle frame; overloading of muck causes the bridge to collapse..." In the battlefield of life and death for special vehicles, the reliability of the chassis directly determines the operating cost. SINOTRUK uses MAN technology genes + localized innovation to reshape the benchmark for special-purpose vehicle chassis.

Two core genes of SINOTRUK chassis

1. Armor level protection: frame and materials

700MPa high-strength alloy steel: the yield strength exceeds the industry standard by 15%, and the thickness of the mining version of the longitudinal beam reaches 10mm.

Local double-layer strengthening: Strengthening of stress concentration areas such as the lifting fulcrum of the dump truck and the saddle of the tractor.

Anti-corrosion process: electrophoretic coating + wax spray technology to cope with saline-alkali soil/high humidity environment (such as port tractors).

2. Power chain golden match

Exclusive solution for dump trucks:

MC13 540 horsepower + Fast 16-speed + ST16 two-stage reduction axle (speed ratio 6.5) → Climbing torque increased by 40%, coal transportation attendance rate is 98.5%.

High-efficiency combination of tractors:

MCY13 single-stage axle (speed ratio 2.85) + SINOTRUK AMT→ Fuel consumption per 100 kilometers is as low as 28L (cold chain logistics fleet data).

Case 1: “Iron Armored Chariot” in African Mining Areas

Challenge: 50°C temperature difference + gravel hitting + 50 tons overload.

SINOTRUK solution: HOWO TX 8×4 chassis + AC16 wheel reduction axle (titanium alloy protective cover), reinforced engineering tires + split balance shaft

Results: The annual transportation volume of a single vehicle increased by 22%, and maintenance costs decreased by 35%.

Case 2: Senegal cold chain fleet

Pain points: high timeliness requirements and sensitive fuel consumption.

SINOTRUK solution: SITRAK C9H 4×2 chassis + MCY11 lightweight bridge (dead weight 7.2 tons), intelligent predictive cruise (based on high-precision map)

Results: A single trip from Shanghai to Guangzhou saved 180L of fuel, and the punctuality rate reached 99.8%.

1. Chassis intelligence

Full-time monitoring: real-time feedback of bridge temperature, vibration, and load, and 3-day advance warning of failures (such as bearing pitting).

OTA upgrade: AMT shift logic is remotely optimized to adapt to plateau/high temperature working conditions.

2. Full life cycle service

Maintenance costs are transparent: Gear oil needs to be changed every 100,000 kilometers · Wheel ends are maintenance-free for 500,000 kilometers

Electric drive chassis: MCY13E electric drive axle is in mass production (range 500km, torque 15000N·m).

Hydrogen heavy truck: Hydrogen fuel cell chassis adapted to refrigerated trucks/municipal vehicles (demonstration operation in 2024).

Autonomous driving chassis: wire-controlled steering + braking, supporting L4 unmanned mine transportation.

“What it carries is weight and what it delivers is value. "Sinotruk's special vehicle chassis, based on reliability, scene as ruler, and wisdom as wings, is becoming an invisible engine for logistics cost reduction and engineering efficiency improvement.
