Cantilever tunnel boring machine

XTR320

The XTR8/320 tunnel boring machine has a large span cutting arm and a small diameter hard rock cutting head, with large driving range and strong rock breaking ability. Double-layer layout, increase the installation and maintenance space, the weight of the whole machine is balanced, and the center of gravity is stable. The automatic cable winding control system combines multi-degree-of-freedom cable elevated, and cooperates with the whole machine to automatically collect and release cables, replacing manual operation, protecting cables, ensuring synchronous advancement of tunneling and support, and improving construction efficiency. The spray system adopts venturi nozzle design, which has high pressure and good effect; at the same time, it can be equipped with dust removal fan to provide a good environment for tunnel construction environment.
