Product introduction

 

HXY-8 (8B) core drilling rig is a medium and deep hole core drilling rig with mechanical drive, vertical shaft rotation, hydraulic feeding and diamond and cemented carbide drilling.

 

HXY-8 is vertical shaft type, hxy-8b is turntable type.

 

This type of drilling rig is suitable for metal and nonmetal solid mineral exploration, shallow oil and gas exploitation, geothermal well exploration, mine tunnel ventilation, drainage and large hole foundation pile construction. Is widely used in geology, metallurgy, coal, hydrology, water wells, engineering and other industries, mainly diamond and cemented carbide drilling core drilling equipment.

 

Technical features

 

HXY-8 (8B) core drilling rig has the characteristics of wide ROP range, reasonable ROP distribution, large power configuration, large output torque, vertical shaft rotation and rotary table rotation structure, horizontal arrangement of winch, etc. it is equipped with water brake, which has large lifting capacity, flexible braking, convenient operation, safety and reliability.

 

Hxy-8b drilling rig can be used not only as a traditional vertical shaft drilling rig, but also as a rotary table drilling rig. It is the preferred equipment for medium deep hole drilling and adapting to China's current medium deep hole exploration work.
