Anchoring the "domestic and international dual circulation" strategy and building a new global operating landscape, vivid scenes of pioneering expansion across mountains and seas are unfolding across CRCHI's global market map—

Breezes sweep the Mediterranean as the "Three-Legged Medusa" shield tunneling machine steadily advances through the high-speed rail tunnel in Sicily, Italy. Its rotating cutterhead precisely tackles the complex geological challenges along the coast, and every inch of progress serves as a powerful footnote to Chinese equipment opening the door to Europe's high-end market.

Snow gleams on the plateau ridge as a customized hard-rock tunnel boring machine precisely breaks through rock amid the towering mountains of the plateau railway. Its robust performance, adapted to high altitudes and ultra-hard rock, injects strong momentum into this super transportation project, fully demonstrating the solid confidence gained from deep cultivation of the domestic market.

During the "14th Five-Year Plan" period, CRCHI anchored itself to the "domestic and international dual circulation" strategy, using the domestic market as the foundation to consolidate its development base and the overseas market as an extension to expand growth space. Through precise positioning, technology adaptation, and service upgrades, it achieved leapfrog development in both markets simultaneously, writing—through tangible market practice—a pioneering chapter of Chinese high-end equipment rooted locally and reaching out globally.

Precise domestic positioning consolidates the ballast of industrial development

Leveraging the advantages of China's ultra-large-scale domestic market, CRCHI closely follows major national strategic deployments and precisely aligns with the needs of segmented fields, achieving continuous breakthroughs in super projects and emerging tracks, making high-end equipment a core force supporting infrastructure construction and industrial upgrading.

In the field of super transportation projects, CRCHI has consistently safeguarded key milestones with "national heavy equipment."

Beneath the Yangtze River—in response to the globally rare challenges of underwater construction in the Haitai Yangtze River Tunnel, the tailor-made super-large-diameter shield tunneling machine "Jianghai" has, with precise attitude control and efficient tunneling performance, laid a solid equipment foundation for the construction of the world's longest underwater highway shield tunnel.

Atop the plateau—deeply involved throughout the construction of the plateau railway, the specially developed large-diameter multi-support hard-rock tunnel boring machine has successfully overcome extreme working conditions such as high altitude, high ground stress, and ultra-hard rock, ensuring the smooth progress of the transportation artery on the snowy plateau.

South China and North China—from the "Jinghua" that helped complete China's longest shield-tunneled expressway tunnel to the "Shenjiang No. 1" undertaking construction of the deepest subsea tunnel, the successful application of a series of customized equipment demonstrates absolute advantages in the field of super projects.

While super projects serve as the "main battlefield" demonstrating hard-core strength, emerging segmented markets have become the "new blue ocean" for growth.

Targeting growth-potential fields such as "major water conservancy" and "major mining," CRCHI's full-face tunnel boring machines and intelligent grouting systems play a key role in follow-up projects of the South-to-North Water Diversion such as the Yangtze-to-Han River Water Diversion, providing efficient equipment solutions for the optimal allocation of water resources.

In the smart parking garage track, the world's largest-diameter shaft boring machine "Dream" has been deployed in an underground project in Jing'an District, Shanghai, innovatively resolving the contradiction between "parking difficulties" and tight land resources in core urban areas, and providing a new paradigm for urban underground space development.

From major projects to livelihood fields, CRCHI continues to consolidate its leading position in the domestic market with precise market positioning and outstanding product strength.

Meticulous overseas cultivation opens new space for global growth

Upholding the "overseas priority" strategy, CRCHI breaks down regional barriers through technology adaptation and deeply cultivates market foundations through localized services. From Europe's high-end market to the hot lands along the "Belt and Road," from single-product exports to full-chain solution supply, it has steadily built a market network covering the globe, enabling Chinese equipment to demonstrate hard-core competitiveness on the world stage.

Breakthroughs in high-end markets have achieved milestone leaps.

On the European field—the success of the "Three-Legged Medusa" shield tunneling machine was no accident. In response to the geological characteristics of the Mediterranean coast—soft soil layers prone to collapse and high risks of seawater infiltration—the R&D team specially optimized the cutterhead cutting angle and slurry support system, and further passed the stringent testing of EU CE certification, winning trust with manufacturing processes that meet international standards.

Along the "Belt and Road," core regions for market expansion have emerged.

In the hot lands of Southeast Asia—on the Luang Prabang to Vientiane section of the China-Laos Railway, 152 sets of customized turnouts and supporting fasteners precisely adapt to the high-temperature and high-humidity environment of Southeast Asia. Since opening to traffic, they have maintained "zero-failure" operation, becoming a benchmark for transnational rail transit equipment cooperation.

At the gateway to West Africa—for Nigeria's Lagos-Ibadan Railway, the successful supply of 236 sets of turnouts not only opened the door to Africa's railway turnout market for the first time, but also established a solid brand reputation through localized technical services, laying the foundation for radiating into the West African market.

Looking globally, from the earth-pressure-balance shield tunneling machine for the Santiago Metro extension line in Chile to the open-type TBM that set a tunneling record at the San Gabán Hydropower Station in Peru, CRCHI's equipment has expanded to cover 24 countries and regions, providing solid support for infrastructure upgrades in countries along the routes in fields such as transportation and energy.

Global collaborative empowerment builds a new ecosystem of win-win cooperation

The continuous expansion of the market map cannot be separated from full-chain capability support. Anchoring the core goal of "value symbiosis," CRCHI has made systematic efforts across three major dimensions—localized technology adaptation, global service upgrading, and ecological co-construction—driving international operations to deeply transform from "product going global" to "full-chain value co-creation," making the new global operating ecosystem more dynamic, resilient, and sustainable.

Localized technology adaptation precisely meets diverse needs. In response to differences in geological endowments and standards and specifications across countries, while also accommodating cultural and emotional resonance, a dual adaptation mechanism of "customized R&D + cultural integration" has been established—

For the Santiago Metro project in Chile, the shield tunneling machine's continuous tunneling system for cohesive soil was upgraded, and the assembly process was optimized in line with local construction rhythms, greatly shortening the equipment commissioning cycle;

For the TBM at the San Gabán Hydropower Station in Peru, a dedicated high-altitude solution was customized. By optimizing the cutterhead's wear-resistant materials and heat dissipation system, it helped the project set an industry record of over one kilometer of tunneling in a single month;

In the South Korean subsea power tunnel project, Taiji elements were ingeniously incorporated into the shield tunneling machine's cutterhead design, making hard-core equipment a bond for conveying cultural goodwill and continuously narrowing the psychological distance with overseas customers.

Global service upgrading consolidates the foundation for steady development. With "efficient response and professional support" at its core, a full-process overseas service guarantee system has been built—

A service network has been deployed in key global regions. The overseas center in Milan, Italy, enables rapid supply of spare parts within 4 hours across Europe. Combined with a remote intelligent operation and maintenance platform, an efficient linkage model of "local immediate response + global remote support" has been established, providing round-the-clock equipment support for overseas projects;

Talent support has been strengthened simultaneously. Through systematic training in international business rules, compliant operations, and product technology, the professionalism of local teams has been enhanced. High-level overseas talent is precisely introduced and cultivated, building an international management echelon that combines strategic vision with practical capabilities, injecting lasting intellectual momentum into global business expansion.

Ecological co-construction gathers the synergy of win-win cooperation. With an open posture, diverse cooperation bridges have been built to achieve win-win outcomes for enterprise development and overseas partners—

Actively appearing at global top-tier industry exhibitions such as bauma Munich in Germany and the South African Mining Exhibition, and proactively engaging with overseas embassies, business associations, and key customers to build a multi-level, wide-coverage international cooperation platform;

Deeply cultivating markets along the "Belt and Road," not only supporting local infrastructure upgrades with high-quality equipment, but also promoting cross-regional cultural exchange and technology sharing by participating in high-end events such as the China-ASEAN Expo and the Global Sustainable Transport Forum;

Strengthening the bottom line of risk prevention and control by introducing professional foreign-related legal service institutions and improving full-process compliance management systems, safeguarding global cooperation with prudent operations and ensuring that the win-win philosophy runs through the entire chain of overseas business.

From hard-core support for super projects to precise adaptation on overseas fields, from products going global to ecological co-construction, the quality and vitality of "Intelligent Manufacturing in China" are increasingly demonstrated as the tunneling machine's cutterhead rotates and customized equipment is deployed.

This impressive report card is CRCHI's proactive action focused on high-quality development, and even more a vivid footnote to the globalization capabilities of China's high-end equipment manufacturing industry—for the enterprise, it is the continuous gathering of development momentum; for the nation, it is the global increment of building a manufacturing powerhouse; for the world, it is a solid demonstration of the strength of Chinese equipment deeply rooted locally and connected globally.
