Product Name: Underground Drilling Jumbo for Fan Hole Drilling Model NO.: GP71 Condition: New Name: Gp71 Underground Drilling Jumbo for Hole Drilling Model: Gp71 Drifter: France Montbert Hc109pr Drilling Depth: 45m Drilling Diameter: 64mm Engine Power: 70kw Total Weight: 13 Ton Overall Size: 7100mm-2400mm-2340mm/2940mm Hydraulic Oil Pump: Sauer Danfoss Advantages: Cost Efficient and Versatile Positioning System Usage: Ore Power Type: Electric Type: Rotary Drilling Rig Trademark: GRANDPLAN Transport Package: 1*40'hq Specification: AS PER YOUR REQUEST Origin: China Product Description GP71 underground drilling jumbo for hole drillingApplication and Feathers:GP71 Mining jumbo suits for various underground non-coal mines, of which cross section is3.5mX3.5m—4.5mX4.5m, and is the first choice for no sill pillar and high-sublevel caving. It can meet the specificdrilling requirement of versatile positioning with reliable sliding table and rotary boom positioning system, highaccuracy drilling, high-power HC109PR drifter, mechanized and high performance, and advanced electric hydrauliccontrolling technology. Stopping in front of a large cross section at a time, it can greatly improve blasting output perunit by drilling parallel and medium-length blast holes.1) Hydraulic components feature of superior performance, high reliable and good versatility. Main hydraulic parts(hydraulic oil pump, multiple directional valves and control spools) are imported with original packaging.2) Hydraulic system has perfect protection device: auto stopping after finishing drilling; anti-jamming mechanism,low oil alarm and other protection devices.3 ) Hydraulic drifter is imported from MonTABERT France, of which hydraulic system is energy-saving, higheffective and reliable.4) Equipped with water system and air system, and could blow holes.5)The machine is modular designed, which makes convenient space for assembling and maintenance.ItemUnitSpecificationsCompletemachineOverallsizemm7100×2400×2340(2940)WeightTapprox.13DrifterModelHC109RP(MONTABERT,France)SteelrodT38Holesizemm64Holedepth(length)m45PercussionpowerKW18.8PercussionfrequencyHZ47Systempressurebar150Rotationspeedrpm145RotationtorqueNm960SoundleveldB105Lub.Airconsumption(3bar)L/s5WaterconsumptionL/min30-50FeederTotallengthmm3155Lengthofsteelrodmm1220FeedingforceKN15-25BoomFeedercompensationmm900Feederliftingangle°+45/-65Feederrotation°±180Feedersliding,lefts&right mm±750Supportcylinderextensionmm1000HydraulicsystemHydraulicpumpsset1(SAUERDANFOSSU.S.A.)Max.systempressurebar230HydraulicoiltankvolumeL124LowoilalarmWatercooledoilcoolerHydraulicoilfilterindicatorDirecthydrauliccontrolsystemAutoanti-jammingmechanismAircompressorpowerKW4ControlsystemMax.displacementL/s10(7bar)GaspressuremeterAirsystemWaterboosterpumpModel:CDL4-16Max.airflowL/min67/minMin.intakepressurebar2WatersystemTotalpowerKW63MainmotorpowerKW55VoltageV440ElectricalsystemFrequencyHZ60OverloadprotectionforelectricmotorsDigitalvoltage/amperemeterPhasesequenceindicatorChargerCablereelm100EngineLuoyangYTOdieselengineChassisRatedpower(2200rpm)KW70Ratedtorque(1650rpm)Nm320Articulatedsteering°±40FixedseatHydraulicpowersteeringsystemHydraulicfourwheeldriveFixedfrontaxleChassisSwingrearaxle°±7Tyres12.00--20Approach/departureangle°15Fronthydraulicjackpc2extensiblepc2ServicebrakescaliperdiscbrakeEmergencyandparkingbrakeshandbrakingFueltankvolumeL60ElectricalsystemV24StorageBatteries2×12V, 70AhTramminglightW6×70CentrallubricationFireextinguisherHorn,signallight,andback-upwarninglightMax.loadingclimbcapability1:4(14º)Max.travelingspeedKm/h10
