Description

XR180D rotary drilling rig is composed of a base unit on crawlers and a drilling application module, it is in the foundation construction for ports, railroad bridges and high-rise buildings and other boreholes in foundation engineering. Suitable for: Telescopic friction and interlocking kelly bars.
1、With the special hydraulic telescopic crawler chassis (TDP series) of rotary drill rig and large diameter slewing bearing, it meets strong stability and 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 flow control, that makes the hydraulic system more energy and efficient.
4、Configure centralized lubrication system, which makes maintenance more convenient.
5、Selection of a variety of specifications for kelly-bar, meeting the efficient construction of different strata.
6、The removable type key of rotary drive makes maintenance and exchange more convenient.
