The CREC-797 slurry shield machine
The CREC-797 slurry shield machine, with a diameter of 13.46 meters, rolled off the production line at the Shunde base of China Railway Engineering Equipment Group Co., Ltd. (CREG) on June 17, which will be used for the construction of the Swinoujscie Tunnel in Poland. This is the first ultra-large-diameter slurry shield machine that China exports to Europe.
The shield machine is 105 meters in length and more than 2,700 tons in weight. It features a unique active arc articulated structure and strong turning correction capacity. Moreover, its cutterhead can move backwards, further improving the equipment’s safety, applicability and environmental friendliness.
The CREC-783 FAT
On June 18, a CREC-783 FAT ceremony was held at CREC National TBM Industrialization Center. With a diameter of 11.09 meters, the tunnel boring machine (TBM) is the largest-diameter hard rock TBM ever exported by China, and will be used for the construction of the Snowy Hydro 2.0 project in Australia.
