Multi-mode TBM
Dual-mode TBM
The dual-mode TBM combines the strengths of a single-shield TBM and an EPB shield. It maintains high advance rates in medium-to-hard rock while remaining capable in soft fracture zones, soft soils and composite strata, with free conversion between the two modes.
Features
Multiple excavation modes deliver strong overall economy and meet construction needs across varied ground conditions

Configuration and engineering
Every CRCHI TBM is engineered to project. Shield diameter, cutterhead geometry, drive power, segmental ring design and back-up arrangement are configured to the alignment, ground conditions and water pressure of the drive. Project-specific scope beyond the standard envelope is engineered to brief, and where a drive calls for it, a machine is developed from the ground up. CRCHI Australia is the engineering, commercial, commissioning and aftermarket point of contact for Australian projects.
