Herrenknecht delivers small diameter shaft drilling solution

First publishedbauma
Daily News
Herrenknecht has developed a boxhole boring machine (BBM), based on its proven microtunnelling pipe jacking technology.

The BBM1100 has been designed to drill slot holes and inclined shafts with a diameter of up to 1.1m and a maximum length of 30m. The machine uses a compact crawler base, with a modular jacking frame, cable drum and power pack that can be positioned separately if required.

The boring unit is positioned within the jacking frame during transportation. When in position the jacking frame can be aligned up to 30 degrees from vertical. The frame is braced against the ground to provide stability and to transfer the operational thrust and torque loads into the rock. The cutting head is designed for hard rock geologies and is equipped with multiple rows of carbide cutters.
