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. drilling diametermm2500Max. drilling depthm90Allowable luffing scope (from center of drill rod to slewing center)mm4100~4400Drilling rig dimension in working condition (L × W × H)mm10480×4800×25155Drilling rig dimension in transport condition (L × W × H)mm16550×3500×3500Weight of overall unit (standard configuration, excluding drilling tool)t92.8EngineModel CUMMINS QSM11-C400Rated power/speedkW298/(2100r/min)Hydraulic systemMax. working pressure of main pumpMpa35Max. working pressure of auxiliary pumpMpa30Rotary driveMax. torquekN •m320Rotational speedr/min5.5~21Crowd cylinderMax.
