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%.
