Bohrtec Front Steer system in combination with a DTH hammer

The Bohrtec Front Steer system in combination with a DTH hammer and optical guidance system is the first and only machine worldwide which is capable to install small product pipes from 400 mm up to 800 mm with an accuracy of +-30 mm on distances up to 100 m in very difficult inhomogeneous ground conditions with bedrock, rock blocs and boulders up to 250 MPa. The capability and suitability of this system was first proven in 2015 on the Hong Kong AEL Tunnel pipe roof project with its 44 drills. Meanwhile this new technology was applied also to another pipe roof project in Qatar.
