XCMG XR220DⅡ CFA Rotary Drilling Rig

XCMG XR220DII CFA adopts hydraulic telescopic TDP series crawler chassis for rotary drilling rigs and large-diameter slewing bearing, which meets the super stability and convenience of transport. It adopts the original imported Cummins electronically controlled turbocharged engine with strong power, and the emission meets the Euro III emission standard.

1.  Adopting special hydraulic telescopic (TDP series) crawler chassis for rotary drilling rigs and large diameter slewing bearing to meet the super stability and convenience of transport.

2. The original imported Cummins electronically controlled turbocharged engine is powerful and its emission meets Euro III emission standard.

3. Hydraulic system adopts limit power control and positive flow control, which makes the hydraulic system more energy-saving and efficient.

4. The main winch adopts single-row rope, which effectively solves the problem of wire rope abrasion and improves the service life of the wire rope; and the main winch is equipped with a drilling depth detection device, and the single-layer winding rope makes the depth detection more accurate.

5. The whole machine is designed to meet the requirements of CE directive, which ensures safety and safer construction.

6. Main winch adopts four-fold wire rope lifting, which effectively improves the lifting force.

7. Centralised lubrication system is equipped as standard, which makes maintenance more convenient.

8. Multi-purpose, CFA method and rotary drilling method can be realised by replacing the working device.

9. Automatic control of the main winch lifts the drilling tools to match the concrete filling, improving the reliability of filling.

10. a variety of specifications of the drill pipe configuration can be selected to meet the efficient construction of different strata.
