In the current era of booming equipment manufacturing industry, Northern Heavy Industries Group Co., Ltd. (hereinafter referred to as "NHI") has achieved breakthroughs in multiple major projects with its profound technological accumulation, strong innovation ability, and excellent engineering strength, setting a new benchmark for the industry and injecting strong impetus into the development of China's equipment manufacturing industry.

Technological Innovation: Leading the Industry in a New Direction

Technological innovation is the core engine for the development of NHI, with multiple achievements reaching the international leading level, opening up new paths for industry progress.

In 2024, the key technology and complete set of equipment for the transportation and mixing of anti-seepage soil materials for the ultra-high earth and rock dam of Shuangjiangkou Hydropower Station, independently developed by NHI, completed the national scientific and technological achievement evaluation, and the main performance indicators reached international leadership. In the automatic blending system of this project, NHI has successfully overcome multiple technical challenges. The advanced intelligent control technology adopted can accurately control the concrete mix ratio error within ±1%; The independently developed intelligent scheduling algorithm can automatically adjust the mixing ratio according to construction needs, greatly improving construction efficiency. This project has achieved significant results, with 11 authorized invention patents and also led the development of 1 group standard, greatly improving the level of scientific research and innovation in the enterprise.

The 65 meters large-span, fully explosion-proof, multi machine common rail intelligent fully enclosed coal material yard bridge scraper reclaimer and gantry scraper reclaimer developed by NHI have won the Excellent Award in the 2nd National Machinery Industry Product Quality Innovation Competition of the "Heli Cup". The project includes two cantilever rotary stackers, two ultra long span bridge scraper reclaimers, and two ultra long span gantry scraper reclaimers. The project is a fully enclosed coal material yard, with strict requirements for explosion prevention of electrical components, acquisition of gas and water sources, and dry mist dust suppression.

In a cement clinker high-temperature resistant conveyor line project in Huzhou, a new type of high-temperature resistant conveyor belt material developed by NHI can operate stably in a high temperature environment of 300℃. This equipment was put into use in September 2018 and is a complete set of belt conveyor equipment independently designed, manufactured, and debugged in China. It has 21 belt conveyors with a total length of 22.331 kilometers and an annual conveying capacity of 10.5 million tons. At the same time, the intelligent monitoring system developed by the project team has achieved real-time monitoring and fault warning of the operation status of the conveyor line, ensuring production safety.

NHI has established a comprehensive technological innovation system, laying a solid foundation for continuous innovation. These innovative achievements not only solve practical engineering problems, but also provide direction for the development of industry technology.

Major Project: Showcasing Strong Corporate Strength

Major projects are the "touchstone" of NHI' strength. In multiple projects, the company has demonstrated strong technical capabilities and the ability to respond to complex challenges.

In the MPGC project, the bridge scraper reclaimer independently developed by NHI has a span of 65 meters and a single machine processing capacity of 6000 tons/hour. The project team has broken through technical bottlenecks such as large-scale structural component manufacturing and high-precision installation, achieving high stability operation and low failure rate of equipment. Its successful operation marks China's leap to an international leading position in the field of large-scale bulk material processing equipment.

The Shuangjiangkou Hydropower Station project is located on a plateau, facing the environmental characteristics of low pressure and large temperature difference between day and night. The NHI project team has specially designed the equipment to ensure stable and reliable operation of the system in areas above 3000 meters above sea level, providing valuable experience for engineering construction in similar plateau environments.

The cement project in Huzhou reflects the professional level of NHI in the field of special conveying. The project team has developed a unique cooling system based on the high-temperature characteristics of cement clinker, which keeps the surface temperature of the conveyor belt within a safe range. By optimizing the layout of the conveyor line, reducing the number of material transfers, lowering dust pollution, and achieving green production.

Sustainable development: driving a new journey of industrial upgrading

NHI has always adhered to the strategy of innovation driven development, established a sound technology research and development system, and established long-term cooperative relationships with multiple universities and research institutes, forming an innovative ecosystem that deeply integrates industry, academia, research and application.

In the future, NHI will continue to deepen its expertise in the field of bulk material conveying systems and increase research and development investment in new materials, intelligence, and other areas. We plan to further increase the proportion of research and development investment in the next three years, with a focus on tackling key technologies such as intelligent operation and maintenance, green energy conservation, and promoting the industry towards high-end and intelligent development. At the same time, enterprises will continue to take innovation as the guide and quality as the cornerstone, contributing greater strength to the high-quality development of China's equipment manufacturing industry.
