The BG 20 H rotary drilling rig has an operating  weight of approx. 58,5 t
It is ideally suited for:

 

  • Drilling cased boreholes (installation of casing by rotary drive of
    optionally by hydraulic oscillator - both are powered by the drilling rig)
     
  • Drilling uncased deep boreholes that are stabilised by drilling fluid
     
  • Drilling boreholes with long hollow stem augers (CFA system),
    without kelly extensions
     
  • Special drilling systems, such as FOW piles, displacement piles,
    cutter soil mixing systems (CSM)
