The type of HF-8 core drill rig is a kind of core drill rig for medium and large depth hole drilling using diamond and carbide-tipped bits, with the technology of mechanical transmission, spindle rotation, hydraulic feeding.
The drill rigs apply to the prospecting of metallic and nonmetallic solid mineral deposits, shallow oil and natural gas exploration and exploitation, geothermal well exploitation, mine ventilation and drainage and large hole diameter basic pile construction.
The features of HF-8 core drill rig as: A large range and reasonable drilling speeds, large capacity of power unit, large output torque and hoister in horizontal arrangement. The rig is equipped with hydraulic brake. As well it's in huge power of lifting, and its braking is easy and quick. Therefore, it's reliable, safe and easy and convenient in operation.
The HF-8 could be used as traditional vertical-spindle drilling rig. They are prior selection equipments and suitable for medium and large depth hole drilling at present China.
