XR 150 D-III

  • It adopts the dedicated hydraulic retractable crawler chassis and large diameter slewing bearing to provide extraordinary stability and transport convenience.
  • It adopts the Cummins electric control turbo-supercharged engine to provide strong power and conformity with Euro III emission standard.
  • With the hydraulic pressure system adopted threshold power control and negative flow control,the system acquired high efficiency and higher energy conservation.
  • Using single rope winding, effectively solve the steel wire rope wear problem, improve the life of wire rope; And drill deep detection device is setted in main winding,single rope to make deep inspection more accurate.
  • The whole machine design meet the requirements of the CE directive, safety guarantee, construction safer.
  • The standard centralized lubrication system, maintenance more convenient.
  • Several drilling rod configurations with different specification are available for efficient construction on different layers.
  • The detachable unit head drive key can provide easy maintenance and replacement.
