JK610 Crawler Mounted Blasting Borehole Drilling Rig Crawler Mounted Hydraulic DTH Drilling Rig borehole drilling machine In contrast with pneumatic drill rig, the air displacement of matched air compressor reduces 30% to 50%. JK610 internal combustion (electric) crawler mounted hydraulic DTH drill rig, is the latest updated product of "Sharp Sword" series, featuring its better performance, lower operation cost and humanized design.  It adopts a 70kW Yuchai diesel engine and hydraulic oil pump station assembly to generate power, allowing rigs to rotation, propelling, lifting, walking and angle positioning.  During operation, only the percussive hammer consumes the compressed air. In contrast with conventional pneumatic drilling rigs, JK610 consumes about 40% to 50% less energy (oil or electricity), and the air displacement of matched air compressor decreases 30% to 50%.  JK610 is equipped with dust collecting system, and wet type dust collector is optional as long as water is accessible on site.  JK610 is mainly applicable to blasting borehole drilling process of hydro project, open pit mining, quarrying, road construction and defense project.
