New paths, new possibilities - tunnel construction for logistics. The machines that drive the drill heads we manufacture enable long tunnels, often used for roads or railway tracks. Our drill heads cut through almost any rock in the tunnel safely and without much wear. The tunnelling machines can thus do their work and ensure that new routes ...
Prufrock. Prufrock is designed to porpoise, meaning it launches directly from the surface, mines underground, and re-emerges upon completion. This allows Prufrock to begin tunneling within 48 hours of arrival onsite and eliminates the need to excavate expensive pits to launch and retrieve the machine. Prufrock is designed to tunnel at a speed greater than 1 mile per week, which is 6 times faster than The Boring
