Brief Introduction
The type of HXY-8B core drill rig is a kind of core drill rig for medium and deep hole drilling using diamond and carbide-tipped bits, with mechanical transmission, spindle rotation, hydraulic feeding. HXY-8B is a diamond drilling rig. The drill rigs can be applied to metallic and nonmetallic solid mineral deposits prospecting; shallow strata oil and natural gas exploration. They could be used widely in geology, metallurgy, coal, hydrogeology, hydrological well and engineering and other industries fields. The HXY-8B could be used as a diamond drilling machine. They are the priority selection equipments and suitable for medium and deep depth hole drilling at present in China.

The HXY-8B spindle type core drilling rig is hydraulic-fed, mechanical transmitted and spindle rotated. It has large and rational range of rotary speed. Its hoister is horizontally arranged and has powerful lifting capacity. Equipped with hydraulic brake, this diamond drilling rig can be stopped easily and quickly. It has large output torque and power unit. It is easy, reliable and safe in operation.

The HXY-8B diamond drilling rig applies to the following fields: geology, metallurgy, coal, hydrogeology, hydrological, engineering and others. It can be used to metallic and non-metallic solid mineral deposits prospecting; shallow oil and natural gas exploration. Beside, it is for medium and large depth hole drilling by using diamond and carbide-tipped bits
