Product Features
JK590C / JK590 are the new generation of internal combustion (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 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 drill rigs, JK590C/JK590 consume about 40% to 50% less energy (oil or electricity), and the air displacement of matched air compressor decreases 30% to 50%. 
Compared with JK590, JK590C is additionally equipped with dust collection system, and wet type dust collector is optional once water is accessible on site. 
JK590C/JK590 are mainly applicable to blasting borehole drilling process of hydro project, open pit mining, quarrying, road construction and defense project.
