Gripper TBM - Experts for tough hard rock

Gripper TBM - Experts for tough hard rock

Herrenknecht Gripper TBMs have proven to be efficient solutions for fast mechanized tunnelling in hard rock on many occasions. Due to the process-typical rock support method without segments, medium to high rock strengths are a requirement for high advance rates. In more fractured geological formations, various systems for immediate rock support behind the cutterhead are installed at the TBM directly.

AVN Machine - Powerful all-rounders for tunnelling in all geologies

AVN Machine - Powerful all-rounders for tunnelling in all geologies

Herrenknecht AVN or Slurry Machines with a cone crusher are all-rounders for safe tunnelling in the diameter range of 0.4 to around 4 meters. These microtunnelling experts show their full potential particularly in non-accessible machine sizes. The slurry-supported excavation concept makes it possible to use these machines in all kinds of ground conditions.

Mixshield - Safe tunnelling technology for heterogeneous ground

Mixshield - Safe tunnelling technology for heterogeneous ground

The Mixshield technology developed by Herrenknecht is an advance on conventional slurry technology. The support pressure in the Excavation chamber is precisely managed using an automatically controlled air cushion. This means that heterogeneous geologies and high water pressures of more than 15 bar can be controlled safely even with very large excavation diameters.
