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, safe, reliable and convenient operation. When rock hardness is <100MPa, it can directly drill φ3500 holes. In general overburden, drilling capacity can reach φ6000. It can be used for large-diameter foundation hole construction in major projects and foundation hole construction in complex strata. |
