Hydraulic Core Drilling Rig

Introduction: HZ series hydraulic core drilling rig is mainly used for geological general investigation and exploration, various kinds of hole in concrete structure,road and tall building foundation exploration,river levees,subgrade grouting hole drilling and direct gr

  • Details

The Hydraulic Core Drilling Machine is used in geological general investigation and exploration. The drill hole diameter can be 150-200mm, and the drill hole depth can range from 100m to 150m.


  • Engine: The engineer of Hydraulic Core Drilling Rig is fed by hydraulic cylinder,the drilling efficiency is higher and it can save labor.
  • Drill rod: 53×59 drilling rod adopted,high rigidity and strong delivery torque.
  • Spindle: Vertical spindle are fixed by four groups of bearing to ensure that the rotary machine is rigid enough for gravel layer and other complex geoloical conditions.
  • Mud pump: Equip mud pump with flow 160L/min, save cost and also make the structure compact.
  • Concentrated handle, small footprint,light weight, strong decomposition, easy to move.
