XRS1050 Rotary drilling rig

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、Highly effective drilling torques, due to the robust drilling head, which choose the import motor and reducer manufactured by internationally renowned company.
8、The single winding roll of main winch enhance the life of rope and the precision of depth detection.
