LIMBERG HYDROPOWER PROJECT, AUSTRIA


SAFE UPWARD MISSION IN HARD ROCK


Tunnelling at a gradient of 42° through hard rock requires bold miners, and special features on the TBM to ensure safety: the Herrenknecht Gripper TBM for the Limberg hydropower project is reliably prevented from slipping backward by the gripper and an innovative knuckle lever device in the twin anti-slip gripper unit. The machine thus remains securely wedged in the rock at all times. herrenknecht.com/limberg
