CR20 0° - 90° 242kw 8.9L NQ 2250m Deep Rock Formation Surface Set
Full Hydraulic Core Drill Rig
Update advanced equipment of HYDX-6 .Drilling machine .
CR series core drill rig is a new type of full hydraulic core
drilling machine designed and manufactured by our factory based on
years of experience in geological exploration and the current
market and users’ most requirements . This machine is used for
plain, hilly terrain, work under the environment of high
temperature, cold areas. Main machine adopts self-propelled chassis
crawler , engine power, mud pump, winch and other integrated
structure ,also can be customized platform truck structure, it is
mainly used for metal and non-metallic solid mineral survey and
exploration, In addition, also can be used in engineering geology
exploration, hydrogeology survey, reconnaissance and exploration of
oil and gas field ,water well drilling etc . The rig has reasonable
layout, compact structure, superior performance, simple operation
and convenient maintenance. It is the ideal coring drilling
equipment.
