BG 20 H (BT 60)

BG_20

Overview

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.
