BAUER BG 20

The BG 20 rotary drilling rig is ideally suited for:

Drilling cased boreholes (installation of casing by rotary drive or optionally by hydraulic oscillator – both are powered by the drilling rig)
Drilling uncased deep boreholes that are stabilized by drilling fluids
Drilling boreholes with long hollow stem augers (CFA system), with or without kelly extensions
Special drilling systems, such as FOW piles, displacement piles, single mixing walls, and cutter soil mixing
The base carrier BT 60 is designed and built by Bauer Maschinen. The engine and hydraulic power pack are mounted in longitudinal direction. Such a construction principle ensures optimal air flow, low transport height, optimal cooling capacity at 40 degrees ambient temperature.
