The GD series large-diameter hydraulic power head drilling rig adopts German large-diameter hydraulic power head drilling technology, featuring strong rock-breaking capability, high operating efficiency,
and safe, reliable and convenient operation.
When rock hardness is below 100 MPa, it can directly drill φ3500 holes.
In general overburden layers, the drilling capacity can reach φ6000.
It can be used for large-diameter foundation hole construction in major projects as well as foundation hole construction in complex strata.
