CCCC Tianhe Mechanical Equipment Manufacturing Co., Ltd. is a subsidiary of China Communications Construction Company Limited, a Fortune Global 500 enterprise. The company specializes in the design and manufacturing of tunnel boring machines (TBMs), offshore vessels, and other equipment, while also providing integrated services for transportation infrastructure construction and management.
The company has an annual production capacity of over 160 TBMs and 50,000 tons of large steel structural components. Its shield machines cover diameters from 0.8m to 18.4m, encompassing full series including full face hard rock TBM, SPB, EPB, and dual-mode types, as well as various models such as composite, open-gripper, vertical, and rescue tunneling machines.
CCCC Tianhe has been deeply committed to independent R&D and technological innovation. From the first domestically developed super-large diameter shield machine "Tianhe" that broke foreign monopolies, to entering high-end overseas markets; from the independently developed "Zhenxing" SPB TBM successfully crossing the Yangtze river, to "Yunhe" setting the record for the longest continuous tunneling without cutter change, and "Cangyuan" conquering the world's longest underwater express roadway tunnel, the company has achieved more than 30 world records. In the marine equipment sector, the world's first heavy-duty dual-processor deep cement mixing (DCM) vessel was successfully applied, and the world's first large-diameter offshore rock-socketed TBM "Haiyang Zhumeng" was unveiled. In tunnel engineering, the world's first pressure-injection TBM "Tianshan" and "Shengli," as well as high-altitude hard-rock vertical TBM "Pioneer," have been successively developed. The equipment has been applied in marine, plain, and high-altitude regions, achieving the transition from "Made in China" to "Created in China" and progressing from follower to parallel competitor to leader.
The company holds the "Special Grade Production Qualification for Full-face Tunnel Boring Enterprises," is recognized as a "High-tech Enterprise," and possesses 9 provincial and ministerial-level R&D platforms, including the Jiangsu Province Postdoctoral Workstation and CCCC Group's Long and Large Tunnel Equipment R&D Center. It has also established the national-level R&D institution — Geotechnical Cutting and Conveying Branch of National Engineering Research Center for Dredging Technology and Equipment. The company is fully committed to becoming a world-class enterprise in high-end engineering equipment manufacturing and full-industry-chain services.
