Product Description Chinese top brand 70 ton rotary drilling rig XR220D for saleProduct Description The machine adapt single row rope for main winch to figure out the wear of steel rope. and extend the life-span. With infrared camera for observing main winch , Manipulator can observe the state of steel rope at day and night in cab. Optional configuration according to customers' requirement (eg: support cylinder , automatic positioning of slewing , Crowd Winch tyro crowd winch CFA, hydraulic casing oscillator, DTH hammer ) Excellent expansibility.Adopting the supercharged engine with European III effluent standard. Meet environmental protection and energy conservation . Super power. With the hydraulic pressure system adopted threshold power control and positive flow control, the system acquired high efficiency and higher energy conservation. 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 intensity , therefore the drill accuracy is heightened . The machine has passed CE certification of TüV Rheinland group.Standard centralized lubricating system, allowing easier maintenance.Specification:DescriptionUnitXR220DMax. drilling diametermm?2000Max. drilling depthm67,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-325Rated power/speedkW242/(2200r/min)Max. working pressure of hydraulic systemMPa35Rotary driveMax. torquekN ?m220Rotational speed(Standard configuration)r/min7~25Crowd cylinderMax.
