The Robbins Company

If the tunnel-geology ranges from soft soils to weathered rock, the Robbins Company offers a solution: The Earth Pressure Balance Machine (EPBM). EPBMs are built for durability and longevity with a thicker cutterhead, an operational life of 10 000 hours, and other features that draw from the company’s extensive background in hard rock. For mixed ground projects, Robbins offers Hybrid Tunnel Boring Machines that feature advantages from two different machine types. New designs for larger diameter machines of 12 to 15 m further streamline in-tunnel conversion between modes.
