ApplicationZDY3200LF(A) and ZDY4000LF are splitting crawler mounted drill rigs with low rotary speed and high torque,Website:http://www.rejeedrilling.com, mainly used to drill gas drainage boreholes with a wide range of possible angles in the roof and water detection/drainage boreholes. It is also used for other cluster borehole drilling operations in underground coal mines.FeaturesThere are three components of ad drill rig:drill unit, pump station and control panel. The control panel can be put on the drill unit during transportation. Three components can be flexibly set up according to the drilling site situation. Rigs have long feed stroke. A new rod can be easily added between rotator and holder to enhance the adaptability and to drill boreholes in a wide range of angles.Technical Data TypeZDY3200LF(A)ZDY 4000LFBorehole depth/m300350Rod diameter/mm7373Rated torque/n.m32004000Rotary speed/r/min60 ~ 20060 ~ 200Max feed force/pull force/kN110123Feed stroke/mm10001000Dip of the main axis/°-30~60-30~60Rated power/kW4555Oil tank volume/L280300Max traveling speed/km/h2.02.0Gradeability/°2020Contact pressure/MPa0.060.07Rotation angle of platform/°Clockwise 90/Counterclockwise 90Clockwise 90/Counterclockwise 90Dimension of the drill unit(LxWxH)/m2.81*1.15*2.02.72*1.15*2.34Dimension of the pump unit(LxWxH)/m2.3*1.15*1.462.3*1.15*1.46
