●  Multi-function: drilling with Continuous Flight Auger (max. Drilling dia. Φ800mm and max. drilling depth 25.5m) or with Kelly system (max. drilling dia. Φ2500mm, max. drilling depth 76m, feed by crowd winch, and it can drill with a casing oscillator) after replacing related components;
●  Dry drilling without slurry circulation to facilitate drilling with fewer accessories and to avoid pollution;
●  The rig owns a high drilling efficiency due to the rotary drive with large output torque;
●  Auger cleaner to reduce labor intensity;
●  The adoption of truss type mast enables greater bending resistance and compressive resistance;
●  When drill with Kelly system, the rig can drill in rock within drillability<grade 8 and uniaxial compressive strength≤ 100 MPa;
●  Caterpillar C9 or Cummins QSL9-C325 intercooler diesel engine owns the functions of load-sensing and output power auto-adjusting; auto accelerating/decelerating function, fuel consumption can be reduced by 5-10%; it meets EU stage III / EPA Tier 3 emission regulation;
●  Embedded system based on work mechanism controller and perfect CAN-BUS technique to take full charge of whole machine monitoring;
●  Hydraulic pump, motor, valve and joint are introduced in well-known brands to ensure high reliability of system; main oil circuit adopts advanced negative control technology and auxiliary oil circuit adopts load sensitive control system, which assures the optimal match of output power and load under all kinds of operating conditions;
●  Meet the standards of city construction law due to its low noise, slight vibration and little pollution during drilling;
