Sinomada Chinese Down The Hole Hammer Drill Rig/Bore Pile Drilling Machine Xr220d

SINOMADA Chinese Down The Hole Hammer Drill Rig/Bore Pile Drilling Machine XR220D  Product DescriptionXR220D Rotary Drilling Rig widely used in boring operation of bored concrete pile in foundation engineering of highway, railways, bridges, ports, docks and high-rise buildings.  Technical Characteristics:1.The machine adapt single row rope for main winch to figure out the wear of steel rope. and extend the life-span. 2.With infrared camera for observing main winch, Manipulator can observe the state of steel rope at day and night in cab. 3.Optional configuration according to customers' requirement Excellent expansibility. 4.dopting the imported supercharged Imported engine with European III effluent standard. Meet environmental rotection and energy conservation. 5.With the hydraulic pressure system adopted threshold power control and positive flow control, the system acquired high efficiency and higher energy conservation. 6.The patented parallelogram articulated structure actualizes a wider work range. The highly strengthened box-type steel structure design makes the mast of highly-rigidity and anticontored, therefore the drill accuracy is heightened. 7.The complete machine has passed CE certification of TuV Rheinland group. 8.Standard centralized lubricating system, allowing easier maintenance. Product ParametersDescription UnitParameter valueMax. drilling diameter mmÆ2000Max. drilling depth m67,standard configuration   (5-section friction Kelly bar)   52,optional configuration   (4-section-locking Kelly bar)Allowable luffing scope (from center of drill rod to slewing center) mm3905~4800Drilling rig dimension in working condition (L × W × H) mm8968×4400×22180Drilling rig dimension in transport condition (L × W × H) mm16360×3250×3535Weight of overall unit (standard configuration, excluding drilling tool) t76EngineModel QSL-325 Rated power/speedkW242/(2200r/min)Max. working pressure of hydraulic system MPa35Rotary driveMax. torquekN •m220 Rotational speed(Standard configuration)r/min7~25Crowd cylinderMax.
