Product Description Hydraulic Rotary Drilling Rig
XR320D Product Information:Adopts the dedicated
hydraulic retractable crawler chassis and large diameter slewing
bearingto provide extraordinary stability and transport
convenience.Cummins electric control turbo-supercharged engine to
provide strong power and conformitywith Euro III emission
standard. With the hydraulic pressure system adopted threshold
powercontrol and negative flow control, the system acquired high
efficiency and higher energyconservation.Using single rope winding,
effectively solve the steel wire rope wear problem, improve the
lifeof wire rope; And drill deep detection device is setted in main
winding,single rope to make deepinspection more accurate.Several
drilling rod configurations with different specification
areavailable 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.Technical Data:DescriptionUnitParameter valueMax.
