BG 24 H (BT 75)

BG_24H

Overview

The BG 24 H 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
