Hydraulic Drilling Rig Features JK590C / JK590 are the new generation of diesel (electric) crawler mounted hydraulic DTH drilling rig, the latest updated version of JK590 series. In contrast with the last generation, they feature lower operation cost and humanized design. They adopt a 70kW Yuchai diesel engine and hydraulic pump station assembly to generate power to rotate, feed, lift, walk and angle position. During operation, only the percussive hammer consumes the compressed air. In contrast with conventional pneumatic drill rigs, JK590C/JK590 crawler drilling rig consume about 40% to 50% less energy (diesel or electricity), and the air displacement of matched air compressor decreases 30% to 50%. Compared with JK590, JK590C is additionally equipped with hydraulic dust collection system, and wet type dust collector is optional if water is accessible on site. JK590C/JK590 are mainly applicable to blast hole drilling process of hydropower construction, open pit mining, quarrying, road construction and national defense construction. Hydraulic Drilling Rig Technical Parameters Model JK590 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 4138mm Rod-changing length 3m Max. horizontal drilling height 3370 Rotation rate 0-80rpm Rotation torque 3000Nm Walking speed 2Km/h, 3Km/h Grade ability 24° Power Yuchai 70KW/Cummins 74KW (optional) Electric motor 45KW Dust collector (optional) Hydraulic dry dust collector Wet dust collector Dimension (LxWxH) 7000mm x 2200mm x 2100mm Weight 6500kg The crawler drilling rigs are widely used in blasthole drilling of mining, hydropower, transportation and defense projects, as well as harbor and channel construction; The hydraulic drilling rigs are specialized in drilling the boreholes of large diameter and depth, for instance, water well drilling and geothermal well drilling.
