CM358A Crawler Mounted Hydraulic DTH Drilling Rig

CM358A Crawler Mounted Hydraulic DTH Drilling Rig Crawler Mounted Hydraulic DTH Drilling Rig Crawler Mounted DTH Drill Rig, Hydraulic Crawler Drills In contrast to the pneumatic drilling rig, energy consumption (diesel or electricity) saves about 40% to 50%. Borehole Diameter 90-165mm Site Condition CM358A crawler mounted hydraulic DTH drilling rig is mainly applicable to the blast hole drilling process of open pit mining, quarrying, hydropower project and road constructions. Product Features CM358A crawler mounted hydraulic DTH drilling rig adopts diesel engine (or electric motor)  and hydraulic oil pump assembly to provide power, allowing rigs to finish moving, rotating, feeding and lifting, as well as angle positioning.  During operation only the percussive DTH rigs consumes compressed air and in contrast to the conventional pneumatic rigs, CM358A saves about 40%~50% of total energy.    Model CM358A Borehole    diameter 90-165mm Borehole    depth 50m Applicable    rock hardness f=6-20 Working air    pressure 1.2-2.4MPa Air    consumption 11-21m³/min Feeding    stroke 3820mm Rod-changing    length 3m Max.    horizontal drilling height 3370mm Rotation rate 0-80rpm Rotation    torque 3000Nm Travel speed 2Km/h Grade ability 24° Power Yuchai 70KW/Cummins    74KW Electric motor 45KW Dust collector (optional) Hydraulic dry dust    collector Wet dust collector Dimension    (LxWxH) 6900mm × 2200mm ×    2200mm Weight 6100kg
