Crawler Mounted Hydraulic DTH Drilling Rig
JK590BC
- Borehole diameter: 90-165mm
- Borehole depth: 50m
- Walking speed: 2km/h, 3km/h
- Optional: Hydraulic dry dust collector/wet dust collector
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.
