The Hydraulic Surface Core Drill is specially designed for diamond core drilling. It provides precise control on the drilling capacity. The drill head is designed to slide and dump, together with the full angle rotation structure for drill mast; it effectively reduces manual inputs and improves efficiency. The hydraulic legs are stretchable, which broaden the bearing surface, and ensure outstanding reliability. The Hydraulic Surface Core Drill includes virtually all operational functions that prevail on the latest models around the world.
Features of Hydraulic Surface Core Drills
-
9 meters rod pulling largely improves drilling efficiency due to rod collection frame design on mast
-
The design of side shift by hydraulic of rotation head largely reduces working tensions and guarantees personel safety
-
Multi-pressure gauge reads real time pressures for kinds of major components
-
High/low speed control of main winch largely meets speed requirements for rods handling
-
Stepless control of mud pump flow facilitates various drilling needs for mud
-
telescopic mast greatly reduces working tensions and improves drilling efficiency.
-
Horizontal extension of jack legs guarantees firm rig standing on the ground.
-
Its full hydraulic concept includes virtually all operational functions that prevail on the latest models around the world.
-
Independent tramming cab set in front provides full view for easy rig walking and driver’s safety
-
Mast dumping guarantees perfect stability during drilling;
-
Independent hydraulic jacks facilities leveling of the rig;
-
Great convenience of control of feed pressure;
-
Standardized parts and components make maintenance and repairing easy;
-
Real time reading of drilling data on gauges on the control panel;
-
