Product Description Product Description HFU-4A Full hydraulic underground drilling rigThe full hydraulic underground drilling rig HFU-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 the large-diameter horizontal drilling surface engineering.Main Feature:1. It is separate in structure, small in size, light in weight, flexible in movement and convenient in operation.2. The hydraulic pump is driven by explosion-proof electric motor through operating system, then the hydraulic pump enforces hydraulic motor to make drill head rotate, and at the same time, the movement of drill head is realized by 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 mast to touches the ground or platform, thus the drill rig will be more stable.5. The swinging arm and mast can do luffing movement, which satisfy 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 angle°0-150Continually adjustableDrill Rod and drill capacitymmΦ55.5×1500 BQ500mmmΦ69.9×1500 NQ400mmmΦ88.9×1500 HQ250mmmΦ114.3×1500 PQ150mDimensions of main machinemm(LxWxH)3730x1200x1850Total weight of main machine, power cabinet and power stationKG3500 Company ProfileFAQ1.
