1. The CUMMINS high-power engine is powerful and forceful which can satisfy the construction requirement in bad conditions;
2. These drills are adopted the advanced control technique includes load sensitive control electro-hydraulic proportion control, and the usage of the import hydraulic parts can make the system work stably and ensure the quality;
3. The machine adopts single row rope for main winch to figure out the wear of steal rope, and extend the lifespan;
4. With the cylinder used for the pull-down of the rotary drive, the system works smoothly and steadily;
5. Electromechanical-hydraulic jointly control method is adapted for the rotary drive, stepless speed regulation. Reasonable torsion-speed rate can meet the construction of varying layer;
6. Home-made undercarriage steel apron wheel，the moving of the machine is controlled by the line which is convenient and safe;
7. Adapting safe operation control system can avoid misoperation and make the manipulation more convenient and security;
8. Adapting independent energy conservation and environment protection oil cooler can make the hydraulic system more adaptive in complicated surroundings.
