XR220D Rotary Drilling Rig
1、Withthe special hydraulic telescopic crawler chassis (TDP series) of rotary drill rigand large diameter slewing bearing, it meets strong stability and easytransportation.
2、Withthe electronically controlled and turbocharged engine of Cummins, which ispowerful and emissions meet Euro Ⅲ standards.
3、The hydraulicsystem adopts the limit of power control and positive flow control, that makesthe hydraulic system more energy and efficient.
4、Withthe single rope main winch, it efficiently solves the problem of wire ropewear, and improves the service life of wire rope; a detection device of drillingdepth on the main winch, and single rope makes deep inspection more accuracy.
5、The designof whole machine meets the requirements of the CE directive, that guarantees safety,and construction safer.
6、Multi-functionsuch as crowd winch、casing driver and hydraulic casingoscillator is optional selected。
7、Configurecentralized lubrication system, which makes maintenance more convenient.
8、Selectionof a variety of specifications for Kelly-bar, meeting the efficient construction of
