Open and Full Shield TBM excavate mountain tunnels by disc cutter mounted to entire surface of the cutter head. We have experience to excavete variable rock condition not only hard rock, but also crush zone.
We have a delivery record of a maximum diameter of 12.84m TBM.<\/p>\n\n\n\n

The open TBM is comprised of cutter head, cutter head drive, main beam, gripper and roof support. This simple structure enables workers to treat cutting face at adjacent point to cutter head.
The open TBM shows high performance and economical excavation in solid bedrock conditions. It is suitable for straight excavation as digging direction is regulated by beam structure.<\/p>\n\n\n\n

The new open TBM combines the features of full shield TBM which is suited for various ground conditions and open TBM which is suited for high-speed excavation in solid bedrock conditions. It can treat looseness from and falling of fragile soil, simultaneously it enables workers to treat cutting face at adjacent point to cutter head.<\/p>\n\n\n\n
