Application
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.
1) Reliable performance
The main accessories are purchased internationally. The diesel engine, hydraulic pump, main valve, motor, travel reducer and key hydraulic accessories are all selected from well-known brands at home and abroad.
2) High efficient
Large torque, high power configuration, reasonable structural design, advanced operation mode and 6m long drill pipe ensure the efficient construction of the drill.
3) Environmental protection
The diesel engine emission is the national third electronic injection diesel engine, low pollution emission, professional noise reduction design, so that drilling Rigs can be suitable for urban construction.
4) Energy saving
The rig uses advanced load sensitive control technology to reduce power consumption and system heat to a minimum.
CR-25 drilling machine is mainly used for inclined and straight hole drilling, which is suitable for geology, metallurgy, coal, nuclear industry, hydrology and other industries. It is a core drilling equipment mainly for diamond and hard alloy drilling.
