The first one in China! The 300 ton mining truck power has passed 18000 hours of acceptance, and Weichai has finally broken through after 10 years of grinding!
The first one in China! 18000 hours!
Weichai Power gnaws on the 'world-class hard bone'
Recently, China's power equipment field has ushered in a historic moment.
At the Heidaigou open-pit coal mine in Zhungeer Banner, Ordos, Inner Mongolia, a witness event was held, bringing together top industry experts, mining giants, and mainstream media.Shandong Heavy Industry Weichai GroupandGuoneng Zhuneng GroupThe crystallization of collaborative innovation - equipped withWeichai 12M55 engineofmiddleThe first 300 ton mining truck in ChinaIt has been officially approved18000 hoursPractical acceptance of heavy load mining!

This is not only a victory for a machine, but also marks a breakthrough for China's 300 ton independently controllable large-scale mining truck powertrain.
A great nation's heavy weapons will eventually have a 'Chinese heart'
Energy security is the 'greatest of nations'.
The mining output of China's open-pit coal mines is the first in the world, but before that, the engines of large ore trucks above 100 tonsLong term dependence on foreign brandsImported mining trucks often cost tens of millions, and the subsequent replacement of engines is even more expensive, seriously restricting the cost security and development lifeline of China's energy industry. For a long time, no domestic engine brand has been able to overcome this hurdle in the "heart" field of the 300 ton ultra large mining truck.
Weichai has gone through 10 years of technological breakthroughs and finallyImplemented this levelThe independent and controllable technology of mining engine assembly.
Weichai's breakthrough not only fills the market gap, but also the national strategic level technological gap.It means that China has truly gained the discourse power in the field of large-scale mining power and is no longer subject to others. From energy security to independent and controllable industrial chain, Weichai's step is a crucial leap for China's equipment manufacturing industry from "big" to "strong".
What does 18000 hours mean?
Calculated based on 15 hours of high-intensity mining operations per day, this is equivalent to an engineContinuous and stable operation for over 1200 daysAfter a comprehensive and multidimensional special acceptance review, the expert group unanimously believes that the performance of the machine has reached the advanced level in the industry, fully meeting the long-term high-intensity operation needs of large-scale mining equipment.

The powertrain of large mining trucks in our country has since stood up.
Data highlights the 'hardcore' strength
What is the strength of this' Weichai Heart 'in the face of old competitors?
Power "temper tantrum":
Boosting ability compared to competitors20% -30% higherThe power for high-altitude and high-altitude mining operations is more abundant;
Burning 'more extreme':
Jet pressure compared to competitors30% -40% higherMore complete combustion and lower fuel consumption;
Brain 'Made in China':
carry, mount, equip, deployExclusive ECU electronic control systemSoftware and hardware are no longer subject to human control, and can be customized and calibrated according to the working conditions of the mining area at any time.

This core system's "completely autonomous and controllable" powertrain truly puts China Mining Truck at the forefront of the industry in terms of energy efficiency and power performance.
From 100 tons to 400 tons,full-scenario coverage
The breakthrough of a 12M55 is backed by the rise of a series.
At present,Weichai has formed a full coverage matrix of 100-400 ton mining truck powerWeichai can provide customized "Chinese solutions" for both harsh open-pit coal mines and thin Qinghai Tibet mining areas.
More importantly, Weichai not only produces it, but also uses it well. Weichai has established a full lifecycle exclusive service system for special mining scenarios,Ensure efficient delivery and equipment operation, and establish nearby mining service bases and spare parts centers，With the optimal three guarantee policy, sufficient spare parts reserves, comprehensive training empowerment, flexible guarantee system, and full lifecycle protectionHelp mining enterprises achieve a win-win situation of safety, controllability, cost reduction, and efficiency improvement，Not only does it make mining companies afford it, but it also makes it affordable and stable for them to use.

Salute to China Power, Meet in 2026
Weichaias2026 International Internal Combustion Engine and Power Equipment ExpoofImportant ExhibitorsThis breakthrough has added a significant touch to the "China Power" movement. From the laboratory to the mining area, from 10 years of technological breakthroughs to 18000 hours of practical verification, Weichai has demonstrated with practical actions what it means to be "independent and controllable, surpassing leadership".
returnLooking back, Weichai's exhibition at the booth since 2025the world's first5-megawatt high-speed diesel generator set "power giant" 20M61Up to nowChina's first 300 ton mining truck engine 12M55Weichai takes one step at a time, constantly pushing the boundaries of Chinese power to new heights.
Finally, we sincerely invite all of you to attend the exhibition and witness firsthand the hardcore strength of more Chinese power, and participate in this glorious event belonging to the power equipment industry together!
