BG 50

 

 

Overview

The BG 50 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, double rotary head drilling systems or cased contiunous flight auger, single mixing walls, and cutter soil mixing
