CR-12 FULL HYDRAULIC CORE DRILLING MACHINE EXPLORATION DRILLING RIG 154KW
CR-12 full hydraulic core drilling machine is a new type of full hydraulic core drilling machine designed and manufactured by Sinocoredrill Group which based on the independent research and development of the advanced technology of the same type drilling machine at home and abroad.
The rig has reasonable layout, compact structure, superior performance, simple operation and convenient maintenance. It is the ideal coring drilling equipment.
1. Machine features:
The machine adopts full hydraulic drive and walks on steel track. The power head is driven by variable pump and variable motor, and the machinery has four stepless speed regulation, with advanced and simple structure. The cylinder is directly fed into the system, the motion is stable and reliable; The mast can adjust the opening Angle in the range of 0° ~ 90°. The center of gravity of the whole machine is low and the stability is good. Provide operators with good visual field and spacious and comfortable working environment; the overall shape is beautiful, and reflects the people-oriented design concept.
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.
2. Field of application
CR-12 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.
Correct use and reasonable maintenance can give full play to the best performance of the machine, can improve work efficiency, and prolong the service life of the machine. Therefore, we hope that the majority of users can operate and maintain in strict accordance with the requirements of this manual.
