In Zhengzhou, Henan province, China Railway Engineering Equipment Group Co Ltd (CREG), the largest tunneling boring machine (TBM) manufacturer in China, has produced an advanced TBM featuring an innovative stone handling system that allows continuous tunneling and precise mechanical transport of boulders. This TBM is set to be used for an underwater segment of Beijing Subway Line 1, showcasing a breakthrough in shield construction technology suited for difficult cobble strata. The development highlights China’s rapid progress in advanced manufacturing, transforming from a manual excavation approach in the mid-20th century to a global leader in tunneling technology.
CREG has maintained the world’s top production and sales volumes of TBMs for eight consecutive years, with its machines excavating more than 5,000 kilometers of tunnels supporting various infrastructure sectors like metro, railway, highway, mining, and water conservancy. China has produced over 4,000 TBMs, covering about 70 percent of the global market, and is exporting to over 30 countries, providing customized services and technical support across diverse climates from Northern Europe to the Middle East.
This technological rise aligns with China’s broader industrial policy for 2026-2030, which aims to consolidate mining, machinery, and construction industries, strengthen industrial chains for self-sufficiency and risk resilience, and build advanced manufacturing clusters. China invested heavily in R&D, with total spending surpassing 3.6 trillion yuan (around $508.22 billion) in 2024, supporting efforts to develop a modern industrial system centered on advanced manufacturing and scientific innovation to maintain global leadership in technology.
A current example of CREG’s international reach is the Hacia TBM, decorated with green aboriginal paintings and bound for Melbourne to assist in a suburban rail loop project designed to reduce traffic congestion and improve public transport efficiency. This reflects China’s capability to provide high-quality machines and after-sales services worldwide, further solidifying its position in the global industrial division of labor.
