Product Features

JK730 automatic crawler mounted drilling rig features its lower operation cost and humanized design. It adopts a powerful diese engine and hydraulic pump station assembly to generate power, allowing rigs to rotating, feeding, lifting, walking and hole positioning. During operation, only the hammer consumes the compressed air. In contrast with conventional pneumatic drilling rigs, JK730 consumes about 40% to 50% less energy (fuel or electricity), and the air displacement of matched air compressor decreases 30% to 50%.
