HCDU-6 HYDRAULIC CORE DRILL
The HCDU-6 Hydraulic Core Drills is special designed for wire-line diamond core drilling. It mainly serves in geological exploration among mining geology,environmental geology and engineering geology areas.It is suitable for deep hole core drilling.
• Long feeding stroke,stabilized pressurization,promoting drilling efficiency.
• Stable infinitely variable speeds, wide-range adjustable, over-load protection,big torque
realized at low speed.
• Telescopic backstay,convenient inclination.
• Large-diameter chuck is suitable for drilling with big size rods.
• Auxiliary equipment, such as chuck,mud pump and mixer, are all driven and operated with
hydraulic power.
• With its integrated design,it is convenient to install,dismantle and move.
