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.
