Horizontal boring machine PBA series

heavy-dutyfor drillingcompact

The compact design allows the use with 1m drilling tools and pipes in small excavations or circular shafts. The PBA 125 RS press drilling rig has been designed for drilling from 2 m diameter circular shafts. For use with longer drilling tools and pipes, this Midi class can be extended to the required size using extension frames. Some machine types are available as an LH version with extended press cylinders for increased advance speed. The application range of the press drilling rigs extends up to a maximum jacking length of over 100 m and serves all requirements of the most varied subsoil conditions. In displaceable soils, the pilot tube method is generally used; in heavy soils or rock, pipe control systems with or without hammer systems are used. The Midi class is suitable for the installation of steel protection pipes, temporary casing pipes, concrete, vitrified clay and GRP jacking pipes.
