2. China North Heavy Industry Company
The successful acquisition of Robbins Company has brought the world-leading hard rock roadheader technology to northern heavy industries. American Robbins Company has a history of 60 years, and its hard rock boring machine technology represents the most advanced level in the world. Its products are all over the world, and its corporate brand enjoys a high reputation in the field of tunnel boring machines in the world. Northern heavy industries is the core enterprise of high-end equipment manufacturing industry in China. Through the combination of the two, northern heavy industries has a full range of full-face roadheader technologies, from earth pressure balance, mud-water balance and hard rock roadheader to composite shield machine and dual-mode shield machine.
3. China Railway Equipment
China Railway Engineering Equipment Group Co., Ltd. is a comprehensive enterprise group integrating four major industrial categories: tunnel boring machine, special equipment for tunnel mechanization, comprehensive development of underground space and steel structure. The annual production capacity is 150 sets of shield and TBM, and it owns 13 large shield manufacturing base.
After China Railway Equipment Corporation and German Wilt Company formally signed the intellectual property acquisition agreement for hard rock boring machine and shaft drilling rig, China Railway Equipment Corporation became one of the three largest enterprises in the world that can independently produce hard rock boring machine (TBM) and have independent intellectual property rights. Products are exported to Singapore, Malaysia, India, Lebanon, Israel, Vietnam, South Korea, Iran, Ethiopia and other nine countries, and the market share has remained the first in China for five consecutive years.
4. China Railway Construction Heavy Industry
Headquartered in Changsha, Hunan Province, China Railway Construction Heavy Industry Group Co., Ltd. is a state-level high-tech enterprise, with more than 200 sets of advanced shield TBM production equipment and an annual production capacity of 120 sets. Products are exported to more than 30 countries and regions such as the United States, Canada, Africa and West Asia.
Railway Construction Heavy Industry is an industry with the largest production capacity, the most complete equipment and the most advanced technology in China. The self-developed high-end shield /TBM with completely independent intellectual property rights is widely used in key projects such as subway, railway, coal mine and water conservancy in more than 30 provinces and cities in China.
5. Hitachi Shipbuilding Company of Japan
Shield machine is in a long-term shrinking trend in the Japanese market, and companies are accelerating their overseas business. Hitachi Shipbuilding has also included overseas production in its plan to catch up with herrick Group, which ranks first in the world. The world's largest slurry shield tunnel boring machine developed by Hitachi Shipbuilding for Seattle, USA, has been manufactured, with a diameter of 17.45 meters, and arrived in Seattle on March 20 13. It laid a foundation for Hitachi's competition in the shield machine industry and its position in overseas markets.
Hitachi Shipbuilding Company started to manufacture shield machines in 1960s, and has produced about 1200 sets. In recent years, the number of domestic subway projects in Japan has decreased, and the overseas market has been fiercely competitive by China companies, and its ranking has been declining.
6. China Communications Tianhe
CCCT Tianhe Machinery Equipment Manufacturing Co., Ltd. currently owns 16 core invention patents of shield machine and 25 core utility model patents of shield machine. With an annual output of more than 100 shield machines, the world's largest shield machine production base (Changshu production base) has been established.
The Great Wall, the largest diameter slurry balance shield machine in China, was successfully rolled off the production line on the handover day. "Great Wall" is the ninth super-large diameter shield machine independently developed by CCCT, and it is the first time to adopt the world's first long-distance excavation technology without changing tools independently developed by CCCT, which can realize continuous excavation of 4,800 meters without changing tools, far exceeding the international maximum excavation distance of 3,000 meters.
7. Restructuring Mitsubishi Heavy Industries (JIMT)
JIMT is jointly operated by Mitsubishi Heavy Industries (MHI), Japanese manufacturer Ishikawa Island Heavy Industries Group (IHI) and steel manufacturing giant Chuantie Co., Ltd. (JFE) to consolidate its manufacturing position of tunnel boring machines.
JIMT will demonstrate the synergistic effect of integration, firmly grasp the domestic demand, accelerate overseas expansion, and provide higher value-added products and services, thus becoming a leading enterprise in the global market and achieving leap-forward development. IHI, JFE Engineering and MHI will cooperate with each other to fully support their business development. Due to fierce competition from companies in China, the ranking is also declining.
8. tunnel shares
Shanghai Tunnel Engineering Co., Ltd. was originally a military secret unit developed and built by China for large tunnels and high-end equipment, with the code name "4046". A grating extrusion shield was designed and manufactured by ourselves, and it was applied to the construction of Haidapu Road cross-river tunnel. The domestic large-diameter slurry balance shield machine "Chuxin" has a tunneling diameter of 9.05 meters, a total length of about 1.32 meters, a total weight of about 1.500 tons and an installed power of 3,500 kilowatts. Developed jointly by Tunnel Co., Ltd., China Railway Construction Co., Ltd. and Ningxia Huadian, it has completely independent intellectual property rights.
Recently, the super-large diameter shield machine "Qiyue" independently developed and manufactured by Shanghai Tunnel Engineering Co., Ltd. of Tunnel Co., Ltd. was successfully debugged in Pudong, Shanghai. The total weight of "July" machine is about 3,200 tons, and the total length is about 99 meters, of which the main machine length is about 16 meters, and the cutting diameter of the cutter head is 14.05 meters.
9. Tertiary industry
Liaoning Sansan Industrial Co., Ltd., which owns the National Shield Machine /TBM Tunnel Boring Machine Engineering Technology Center, can independently design, develop, manufacture and assemble, and independently produce full-face tunnel boring machine (TBM) with independent intellectual property rights. It has the world's largest manufacturing workshop and the world's most advanced complete set of CNC machining clusters, with an annual output of 100, and its products are distributed in the fields of subways, highways, railways and cross-harbour tunnels at home and abroad.
Another landmark product of the tertiary industry came out, and the super-large slurry balance shield machine "Qianjiang", the key project of Hangzhou Asian Games-the second phase of Hangzhou Road upgrading and reconstruction project, successfully rolled off the assembly line in Wuhan and passed the acceptance test.
