On November 11–12, 2025, the National Defense Science and Technology Achievement Appraisal Meeting was successfully held in Beijing, focusing on three major technical achievements completed by North Industries Group Corporation (Beifang Shares): "Development of the TR100E Pure Electric Mining Vehicle," "Key Technologies of Core Systems for Mining Vehicles and Complete Vehicle Integration Development," and "Research and Application of Intelligent Assembly Process for Large Wet Disc Brakes."

Experts attending the meeting carefully listened to the project reports, reviewed key technical documents, and conducted in-depth questioning and discussion on the innovativeness, advancement, and application prospects of the achievements. Group leaders highly affirmed the organization of the meeting and the quality of the deliberations, considering the process rigorous and the content solid, which laid a firm foundation for the scientific evaluation of the achievements.

Following authoritative appraisal, all three achievements demonstrated significant technological breakthroughs and industry-leading value:

• "Development of the TR100E Pure Electric Mining Vehicle": the overall vehicle technology reached the internationally leading level;

• "Key Technologies of Core Systems for Mining Vehicles and Complete Vehicle Integration Development": the overall technology reached the internationally advanced level, with the suspension technology achieving the internationally leading level;

• "Research and Application of Intelligent Assembly Process for Large Wet Disc Brakes": the overall technology reached the domestically leading level.

These achievements mark that China has successfully broken foreign technological monopolies in the field of pure electric mining vehicles and core systems, achieving localized substitution of key systems such as electric drive. The research and application of intelligent assembly processes have significantly improved the manufacturing precision and production efficiency of core components, providing key technical support for large-scale mass production of equipment.

The appraisal committee unanimously agreed that the three achievements pass appraisal and noted that they possess important value for promotion and application. Beifang Shares will also actively incorporate expert opinions, accelerate the transformation and industrialization of the achievements, and continue to inject innovative momentum into the high-quality development of China's mining equipment.
