Compact Machines

For inner-city projects Bohrtec developed the range of Compact Machines:
BM 150 D for trenchless construction of connecting sewers up to ID 200 or for direct underground connection to existing main sewers.
BM 150 DT for construction of drillings out of jacking pipes or tunnels ≥ 1200 mm.
BM 400 or BM 400 S for construction of small sewers up to ID 400.
BM 500 S for construction of small sewers from ID 300 to ID 800.

Long Frame Machines

The long frame machines were developed for projects where the size of the launch shaft plays a minor role. These machines allow for the use of steel pipes up to 18 m length. The jacking machines BM 400 LS, BM 600 LS, BM 800 L and BM 800 LS enable economic drillings up to 120 m length and up to 1,6 m OD.

LSC Machines

The BM 400 LSC and the BM 600 LSC have a modular frame design. The special design of these machines also allows a setup in small circular launch shafts.
