Tunnel Boring Machinery is one of the most important products in our company. Since 1995, we have installed and improved 5 sets of tunnel boring machines for the No.1 and No. 2 lines of Guangzhou Metro. In 2000, we cooperated with HERRENKNECHT AG, a Germany company, to manufacture 2 sets of tunnel boring machines for the No.2 Lines of Guangzhou Metro. Until now, we have manufactured more than 10 sets of φ6.3m tunnel boring. We’ll keep on cooperating with HERRENKNECHT AG. to make the tunnel boring machine be manufactured locally.
