XCMG rotary drilling rig XR460D
1、Super stability and convenience of transportation, for use the special hydraulic and telescopic crawling chassis of rotary drilling rig.
2、The Cummins engine provides strong power, and The noise and emission meet Europe Ⅲ standard.
3、The design of big trigonal luffing mechanism bring a significant improvement in stability.
4、The quality of work is enhanced by increase the mast section to reduce mechanical wobble of the mast.
5、Ensure verticality of the hole by add a bracket for drill pipe.
6、High-performance and more energy-efficient, due to the technology of load-sensing hydraulic system.
7、It can be equipped with a variety of drilling tools to realize drought and wet working.
8、The single winding roll of main winch enhance the life of rope and the precision of depth detection.
9、It can choose winch pull-dowm.The travel is 16 m, The Max. force of winch pull-down is 500kN
10、Highly effective drilling torques, due to the robust drilling head, which choose the import motor and reducer manufactured by internationally renowned company.
11、The worker can observe the rope in cab day and night by infrared camera.
12、Standard centralized lubricating system, allowing easier maintenance.
