CR25 Hydraulic Core Drilling Rig is reasonable in design, excellent in performance, easy for operation and convenient for maintenance.
CR25 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.
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.
The drilling rig has reasonable layout, compact structure, superior performance, simple operation and convenient maintenance. It is the ideal coring drilling equipment.
