Chinese Tunnel Boring Machines Now Win 65% of Global Orders — Infrastructure Trade Shift
Chinese tunnel boring machine manufacturers now capture approximately 65% of global TBM orders by unit count. CREG and CRCHI have developed machines exceeding 16 metres in diameter, competing directly with Herrenknecht and Robbins at 30-40% lower cost while demonstrating comparable performance on major infrastructure projects worldwide.

Rise of Chinese TBM Manufacturing#
China's tunnel boring machine industry developed in response to the country's massive metro and rail infrastructure programme, which required hundreds of TBMs simultaneously. This domestic demand created manufacturing scale that no other country could match. China Railway Engineering Equipment Group (CREG) and China Railway Construction Heavy Industry (CRCHI) now produce over 100 TBMs annually, compared to global demand outside China of approximately 80-100 units per year. The technology transfer that initially relied on German and Japanese designs has evolved into indigenous innovation, with Chinese manufacturers now holding patents on cutterhead designs, guidance systems, and segment erection technology.
Global Order Share and Key Export Projects#
Chinese TBMs have been deployed on major infrastructure projects across Asia, the Middle East, Africa, and increasingly in Europe. Notable exports include machines for the Moscow Metro, Istanbul Metro, Mumbai Metro, and several Middle Eastern water tunnel projects. CREG supplied TBMs for the Tuen Mun-Chek Lap Kok Link in Hong Kong, demonstrating capability on technically demanding subsea tunnelling. The Italian market has also seen Chinese TBM adoption, with machines deployed on high-speed rail tunnels. Total Chinese TBM exports exceeded $2.5 billion in 2025, with order books extending through 2029 for several manufacturers.
Pricing and Delivery Timelines#
A standard 6-metre diameter earth pressure balance TBM from CREG costs approximately $8-12 million, compared to $15-20 million for a comparable Herrenknecht machine. Larger diameter hard rock TBMs show similar proportional savings. Delivery timelines from Chinese manufacturers are typically 10-14 months from order to factory acceptance, compared to 14-20 months for European manufacturers. This faster delivery reflects both larger factory capacity and willingness to begin manufacturing before final design approval, which carries risk but appeals to projects with tight construction schedules. Chinese manufacturers also offer more flexible payment terms, typically requiring 20-30% upfront compared to 40-50% from European competitors.

Technical Performance and Reliability Data#
Performance comparisons between Chinese and European TBMs show narrowing gaps. Chinese machines regularly achieve advance rates of 15-25 metres per day in favourable ground conditions, comparable to European equivalents. Cutterhead life and cutter consumption rates remain areas where European machines show some advantage, particularly in abrasive hard rock conditions. The most significant reliability concern with Chinese TBMs relates to control systems and software, where European manufacturers maintain a technology lead in automated guidance and real-time geological prediction. Procurement teams should evaluate these specific subsystems carefully rather than making blanket quality assumptions.
Procurement Strategy for Infrastructure Agencies#
Infrastructure agencies evaluating Chinese TBMs should request detailed performance data from comparable completed projects rather than relying solely on factory specifications. Site visits to operating Chinese TBMs on projects with similar geological conditions provide the most reliable assessment of likely performance. Contracts should specify key component suppliers for critical systems including main bearings, hydraulic systems, and guidance electronics. Some agencies adopt a hybrid approach, purchasing Chinese TBM shells and structures while specifying European control systems and key components, achieving 20-25% savings compared to fully European machines while maintaining technology confidence in critical subsystems.
People also ask
How much does a Chinese tunnel boring machine cost?
A standard 6-metre diameter earth pressure balance TBM from Chinese manufacturers costs approximately $8-12 million, compared to $15-20 million for a comparable machine from Herrenknecht or Robbins. Larger diameter and hard rock machines cost proportionally more.
Are Chinese TBMs as good as German ones?
Chinese TBMs have closed the performance gap significantly and achieve comparable advance rates in most ground conditions. European machines still show advantages in control system sophistication and cutter life in abrasive rock. The reliability gap has narrowed substantially over the past decade.
Which countries use Chinese tunnel boring machines?
Chinese TBMs operate in over 30 countries including Russia, India, Turkey, Italy, Singapore, and multiple Middle Eastern and African nations. They have been deployed on metro systems, water tunnels, rail tunnels, and road tunnels worldwide.
