Video shows how a Robbins Main Beam, or open-type, tunnel boring machine (TBM) excavates tunnels in hard rock.
Find out about Norway’s Røssåga Hydroelectric Project, the first TBM to be used in the country in more than 20 years. Watch in-depth site interviews about machine performance in incredibly hard, abrasive rock, remote site conditions, and the future of TBM use in Norway.
Learn more about the Robbins Motorized Small Boring Unit (SBU-M) in this 3D animation. With continuous steering capabilities and an in-shield drive motor, the SBU-M can make the grade on long gravity sewers and other line and grade sensitive utility tunnels.

Soft clay soil, an array of boulders, and sharp turns have each added an extra layer of difficulty on the Chengdu Metro Line 2 project. Custom-engineered with active articulation systems, the two Robbins 6.3m EPBs have been carving their paths at speeds up to 180 meters per week.
This video describes custom cutterhead design for Robbins soft ground tunnel boring machines, known as Earth Pressure Balance Machines.
