XR180D Rotary Drilling Rig
The XR180D rotary drill rig enjoys the following features.
- (1) The use of hydraulic telescopic TDP series track chassis and large diameter of slewing bearing ensures super strong stability and convenience of transportation.
- (2) Cummins electronically controlled turbocharged engine to provide strong power, convenient and efficient service, meeting Euro III emission standard.
- (3) Single row of rope and main winch effectively solve the wear issue of steel wire rope, and increase its service life. The main winch is equipped with drilling depth detector, and the single row of rope makes the depth detection more accurate.
- (4) Hydraulic main system adopts positive flow control, load sensing control and power limit control technologies, making the hydraulic system more efficient.
- (5) Detachable drive key of rotary drive makes it easy for maintenance.
The XR180D rotary drill rig is a classical model in the XR-series.
