Hfu-4A Full Hydraulic Underground Drilling Rig Easy Maintenance

Hfu-4A Full Hydraulic Underground Drilling RigProduct Description                                                                                       HFU-4A full hydraulic underground core drilling machine is mainly applied in the fields of coal, geology, metallurgy and engineering. It is used for drilling large diameter Gas suction hole in mines, gallery as well as coal mine, water injection hole, and big diameter Horizontal hole. It can meet the big diameter Roller drilling, hard tungsten-carbide drilling and percussive-rotary drilling.Main Features1. 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.Technical SpecificationsItemsUnitDataRemarkRated rotate torqueN.m1340When 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 Introduction                                                                               Hanfa Group established in 1998 is a key enterprise in the industry of geological exploration and water well field, with the ability to research,manufacture and market.
