CR26 NQ 2250M HQ 1850M Mining Core Drill Rig Exploration Geological Mine Diamond
CR22 Hydraulic Core Drilling Rig is reasonable in design, excellent in performance, easy for operation and convenient for maintenance.
The core drill rig of full hydraulic and rotator adopted the technology of wire-line coring has been the dominant type rig for solid mineral deposits prospecting in developed counties in the world. It could be applied to exploration and prospecting of geology, metallurgy, coal, petroleum, natural gas, groundwater and other industries.
CR22 can be applied to both slant and vertical drilling. Being a rig equipped with diamond and the carbide alloy bit drilling, it can be used in the fields of geology, metallurgy, coal mining, nuke industry and hydrology measuring.
