Fully Hydraulic Underground Drilling Rig for Mining Tunnels and Coal Mines

Product DescriptionModel:RCH-4A hydraulic underground drilling rigDrilling depth:550mDrilling diameter :BQ,NQ,HQ,PQPower: 75KW electric motorWalking way : skid mountedDrilling way :mud pump rotary drillingApplication :Used in mines, tunnels, the coal mine gas drainage by large diameter gas holes, water injection hole and surface engineering of large diameter horizontal drilling construction.The full hydraulic underground drilling rig RCH-4A is applied to the following fields: coal, metallurgy, geology, and engineering, etc. It is used in the large-diameter gas drainage and the water injection hole of mine, tunnel, and coal mine. It is also used in large-diameter horizontal drilling surface engineering. Advantages1. This drilling rig is separate in structure, small in size, light in weight, flexible in movement, and convenient in operation.2. The hydraulic pump is driven by the explosion-proof electric motor through the operating system, then the hydraulic pump enforces the hydraulic motor to make the drill head rotate, and at the same time, the movement of the drill head is realized by the oil cylinder & chain double speed mechanism.3. Hydraulic chuck can satisfy the function of shackles and power-off protection.4. The sliding and extending & retracting function of the mast makes it convenient for the bottom of the mast to touches the ground or platform, thus this hydraulic drilling rig will be more stable.5. The swinging arm and mast can do luffing movement, which satisfies the request of multi-angle drilling.6. The range of spindle rotating speed is wide and the torque is large.Product ParametersItemsUnitDataRemarkRated rotate torqueN.m1440When 490r/minRotate speedr/min0-489-876/0-671-1200/Lifting capacitykN98/Feeding capacitykN50/Electromotor rated powerkw75Y280S-4-35BElectromotor rated RPMr/min1478/Feeding strokemm1800/Rotator rising speedWorkingmm/s31.4/Max.mm/s88/Rotator Declining speedWorkingmm/s61.58/Max.mm/s172.4/Hydraulic pumpMain pump ERR100BRated pressureMPa28/Max. displacementL/min148/Mid pump A10VO18Rated pressureMPa28/Max. displacementL/min26.64/Rear pump A10VO10Rated pressureMPa28/Max. displacementL/min14.8/Wireline winch lifting capacity(single wire)t0.8/Wireline winch Speed (min)m/min91Wireline Dia.Mm6Wireline winch Speed (max)240Mud pump max displacementL/min160When 2.5MPaMud pump max pressureMPa10When 44L/minMast inclined angledegree0-150Continually adjustableDrill Rod and drill capacitymmDia.55.5*1500 BQ550mmmDia.69.9*1500 NQ400mmmDia.88.9*1500 HQ250mmmDia.114.3*1500 PQ150mDimensions of the main machinemm(LxWxH)3730x1200x1850Total weight of the main machine, power cabinet, and power stationKG3500/Company ProfileHenan Rancheng Machinery Co.,LTD is one professional supplier drilling rigs in China ,weare dedicated in designing and manufacture water well drilling rig ,rotary drilling rig ,anchor drilling rig ,core drilling rig ,DTH drilling rig ,solar pile driver,mud pump ,air compressor and drilling tools etc,we have advanced technology ,Modern equipment, first-class team and rich experience ,our products passed ISO9001 ,CE etc certificated ,they are exported to around 200 countries and areas in the world ,get very good feedbacks from our clients.We Pursue the principle of "Customer First, Integrity First", we are sincerely expecting to cooperate with you!!!   FAQ1.Why choose us ? Rancheng Machinery is a very professional drilling rig supplier in China.
