Dimensions
Crowd winch type
The BG 25C rotary drilling rig has an
operating weight of approx. 74 to and a
torque of 245 kNm. 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)
• Drilling uncased deep boreholes that
are stabilised by drilling fluid
• Drilling boreholes with long hollow stem
augers (CFA system), with or without
kelly extensions
• Displacement piles
