●  Multi-function: drilling with Continuous Flight Auger (max.drilling dia. Φ 750mm and max. drilling depth 17m) or with Kelly system (max. drilling dia. Φ1500mm and max. drilling depth 46m) 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;
●  Cummins QSB6.7-190 (EU / EPA Tier 3 III) or Isuzu CC-6BG1TRP(EU stage II/EPA Tier 2) stage 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%;
●  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.
