Herrenknecht - MH Box Machine Tunnel Boring Machines

The demand for new underground infrastructures for pedestrians and cyclists is increasing along with the rapidly growing traffic load in large and megacities. This makes it necessary to cross beneath a great number of busy junctions, expressways or railway routes at short distances and at a low depth. The high traffic burden at these intersections makes aboveground interventions extremely difficult or even impossible without a great deal of additional work and expense. 

Herrenknecht has developed the so-called MH Box Machine as a solution. It is a further development of the MH partial-face excavation technology that has been used successfully for more than 35 years. These machines have established themselves as the most efficient tunnelling equipment when building tunnels and pipelines above groundwater level, because of their simple design, low acquisition and operating costs and excellent performances.
