The Core Drilling Rig is a light type machine at high speed with hydraulic feeding.
- Drillings for the general exploration and investigation of solid mineral deposit, engineering geotectonic survey and concrete structure inspection holes.
- Diamond drill bit, alloy drill bit and steel roller drill bit and so on are available for drilling according to different geological structures.
- When the final holes are respectively 75mm and 46mm in diameter, the rated hole depths are separately 100m and 180m. The maximum of depth may not exceed 110% of that drilled in each hole. The maximum allowable hole diameter is 150 mm.
- With hydraulic feeding device, elevated drilling efficiency, reduced labor strength.
- The rig is equipped with an upper spherical jaw holding mechanism and hexagonal drive drilling rod which can be replaced without shutdown, high efficiency, safe and reliable.
- A hole bottom pressure gauge is mounted indicating the pressure in order to control the status inside the hole.
- Compact structure, small volume, lightweight, high detachability, easy transportation and suitable for the operations in plains or mountain areas.
