XCMG 220kN XR220D hydraulic rotary drilling rig machine.
1,Withthe special hydraulic telescopic crawler chassis (TDP series) of rotary drill brigand large diameter slewing bearing, it meets strong stability and easy transportation.
2,Withthe electronically controlled and turbocharged engine of Cummins, which is powerful and emissions meet Euro Ⅲstandards.
3,The hydraulic system adopts the limit of power control and positive flow control, that makes the hydraulic system more energy and efficient.
4,Withthe single rope main winch, it efficiently solves the problem of wire rope wear, and improves the service life of wire rope; a detection device of drilling depth on the main winch, and single rope makes deep inspection more accuracy.
