JK730 Automatic Crawler Mounted DTH Drilling Rig

JK730 Automatic Crawler Mounted DTH Drilling Rig Crawler Mounted Hydraulic DTH Drilling Rig Crawler Hydraulic Dth Drilling Rig, Crawler Mounted Drilling Rigs, hydraulic drilling rig JK730 automatic crawler mounted drilling rig features its lower operation cost and humanized design.  It adopts a powerful diese engine and hydraulic oil pump station assembly to generate power, allowing rigs to rotation, feeding, lifting, walking and angle positioning.  During operation, only the percussive hammer consumes the compressed air. In contrast with conventional pneumatic drill rigs, JK730 consumes about 40% to 50% less energy (fuel or electricity), and the air displacement of matched air compressor decreases 30% to 50%. We design and manufacture several types of LED display, each of them meeting the demands of different markets and usage situations, whether they are outdoor or mobile advertising, indoor events, sports events or traffic signs.We design and manufacture several types of LED display, each of them meeting the demands of different markets and usage situations, whether they are outdoor or mobile advertising, indoor events, sports events or traffic signs.   Model JK730 Borehole diameter 90-165mm Rod carousel Rod capacity 5+1/6+1 Rod length 3m Rod diameter φ76mm Auto rod-changing depth 18m/21m Applicable rock hardness f=6-20 Working air pressure 1.2-2.4MPa Air consumption 11-21m³/min Feeding stroke 3850mm Rod-changing length 3m Max. horizontal drilling height 2970mm Rotation rate 0-90rpm Rotation torque 3300Nm Travel speed 2Km/h, 3Km/h Grade ability 20° Power Yuchai 92kW (optional Cummins 97kW) Dust collector (optional) Hydraulic dry dust collector Wet dust collector Dimension (LxWxH) 7000mm×2400mm×3350mm Weight 9000kg
