The 2026 Tibet Nyingchi Construction Expo, themed "Building Dreams on the Plateau, Constructing a Green Future," officially opened on May 28. Weichai showcased its portfolio of benchmark products, including high-efficiency energy-saving generator sets, SOFC power systems, battery, motor and electric control systems, and hydrogen fuel cells. These solutions demonstrate a comprehensive green and low-carbon approach covering construction, transportation, and power generation, supporting the sustainable development of major national plateau projects.

With the continued advancement of the Western Development Strategy, infrastructure development on the Tibetan Plateau has entered a new phase. At the Nyingchi Expo, Weichai’s featured products underwent specialized green and low-carbon optimizations for high-altitude operating conditions, effectively addressing the challenge of balancing infrastructure development with ecological protection.

In the conventional power energy sector, Weichai offers a comprehensive range of products across all fuel types and application fields.

The two diesel generator sets showcased at the exhibition serve as core power equipment for plateau infrastructure due to their exceptional adaptability:

16M55 High-Power Generator Set: Specifically engineered for high-reliability power requirements, featuring dynamic high-altitude data self-adaptation and optimized cooling, lubrication, insulation, and starting systems to balance efficiency and energy conservation;

WP13 Rental Generator Set: Focused on the full spectrum of rental applications, it effectively resolves cold-start issues at high altitudes and features a high protection rating and intelligent operational control to ensure stable, efficient, and safe power supply. Currently, Weichai holds a 60% market share in the prime power market for rental applications.

In the green and low-carbon power sector, Weichai has mastered core key technologies for SOFC power systems. These products achieve a comprehensive efficiency exceeding 60%, a combined heat and power efficiency of over 85%, and maintain a power derating correction factor of 95.5% at 4,000 meters and 86.6% at 5,000 meters. By providing clean, low-carbon, and quiet power, Weichai facilitates a win-win situation for infrastructure development and environmental protection on the plateau.

In the field of battery, motor and electric control systems, Weichai has completed custom development for high-altitude operating conditions.

The battery products feature superior heat dissipation, high structural integrity, and industry-leading sealing and protection performance;

The motor products offer high insulation and reliability, suitable for various operating environments;

The electronic control products feature a high-vibration-resistant design and remain fully functional at altitudes of up to 5,500 meters.

In the hydrogen energy sector, Weichai’s hydrogen fuel cell engines offer a power range of 80–300 kW. These engines have passed endurance tests for 30,000 hours and maintain reliable operation at altitudes of 5,000 meters, providing innovative solutions for zero-carbon transport and green infrastructure in high-altitude regions.

In the construction equipment sector, Weichai leverages its comprehensive product matrix—comprising traditional engines, new energy products, and hydraulic components—to maintain industry-leading market shares in segments including 3-ton and above loaders, wide-body dump trucks, cranes, and bulldozers.

Our products support major national engineering projects, including water conservancy, railways, wind power, the 'East Data, West Computing' initiative, and large-scale open-pit mining in high-altitude areas. Positioned at the new development stage of the Western Development Strategy, Weichai is committed to fostering a harmonious balance between ecological protection and infrastructure construction in the western highlands.
