overview

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.
