XR180D Rotary Drilling Rig 1、With the special hydraulic telescopic crawler chassis (TDP series) ofrotary drill rig and large diameter slewing bearing, it meets strong stabilityand easy transportation.
2、With the electronically controlled and turbocharged engine of Cummins,which is powerful and emissions meet Euro Ⅲ standards.
3、The hydraulic system adopts the limit of power control and positive flowcontrol, that makes the hydraulic system more energy and efficient.
4、With the single rope main winch, it efficiently solves the problemof wire rope wear, and improves the service life of wire rope; a detectiondevice of drilling depth on the main winch, and single rope makes deepinspection more accuracy.
5、The design of whole machine meets the requirements of the CEdirective, that guarantees safety, and construction safer.
6、Configure centralized lubrication system, which makes maintenancemore convenient.
7、Selection of a variety of specifications for Kelly-bar, meeting the efficient construction ofdifferent strata.
8、Multi-function such as crowd winch、spin-offof rotary drive、casing driver and hydraulic casingoscillator is optional selected。
9、The removable type key. Of rotary drive makes maintenance andexchange more convenient.
