Gripper TBM - Herrenknecht AG

When tunnelling with a Gripper TBM, a rotating cutterhead equipped with disc cutters is pressed against the tunnel face with a pressure of up to 32 tonnes per disc. Due to the rolling movement of the cutter, single pieces – so- called chips – are broken out of the rock. Water jets can cool the cutting tools and reduce dust formation.
