Low Headroom

 

The BG 24 H LOW HEAD is a compact drilling rig with a torque capacity of 250 kNm, which is designed especially for working in limited headroom conditions.

It 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) and

  • Drilling uncased deep boreholes that are stabilised by drilling fluid.

The standard height of the rig is 8.5 m. Drilling depths of 19 m can be reached with a 5-fold kelly bar. The base carrier BT 75 is designed and built by Bauer Maschinen.

It is especially characterized by an optimal cooling capacity up to 45°C ambient temperature at moderate noise emission. The rig can be modified to a standard kelly drilling rig with a height of 21.90 m by adding an upper mast section, a standard mast head and a lower mast extension.
