JK590BC-2A Crawler Mounted Hydraulic DTH Drilling Rig

The crawler-mounted DTH drilling rig is well designed to drill through rocks easily, efficiently and at a low cost. As a star product among separated DTH drilling rig, it has sold thousands of units worldwide.

The drilling rig is powered by a power unit composed of diesel engine and hydraulic oil pump, with a hydraulic motor facilitating drilling, feeding, lifting, walking and hydraulic cylinder positioning. During operation, compressed air is utilized only by the DTH hammer, which reduces air compressor’s output by 30% to 50% compared to pneumatic drill rigs and lowers energy consumption (fuel oil or electricity) by 40% to 50%.

Applications
The drilling rig is widely used for hydro-power engineering, open pit mining, road construction, drilling and blasting operation of national defense engineering.
