CR25 Surface Core Drilling Rig

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.
