Product Description

Hydraulic Rotary Drilling Rig XR220D

Product Information:

Adopts the dedicated hydraulic retractable crawler chassis and large diameter slewing bearing
to provide extraordinary stability and transport convenience.

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.Several drilling rod configurations with different specification are
available for efficient construction on different layers.

The whole machine design meet the requirements of the CE directive, safety guarantee,
construction safer. The optional centralized lubrication system, maintenance more convenient.
The detachable unit head drive key can provide easy maintenance and replacement.
