Adopt imported Cummins turbocharging engine , CE standard .Centralized lubricating system .XCMG XR260D rotary drilling rig uses a hydraulic telescopic crawler chassis and a large-diameter slewing ring for rotary drilling rigs to meet superior stability and transportation convenience. The imported electronically controlled turbocharged engine has strong power and emissions meet Euro III emission standards. The hydraulic system uses extreme power control and positive flow control to make the hydraulic system more energy efficient. The single-row rope main hoisting effectively solves the problem of wire rope wear and effectively improves the service life of the wire rope; and the drilling depth detecting device is provided on the main hoist, and the single-layer rope winding makes the depth detection more accurate.
