KG320 Rock Blasting DTH Drilling Rig For Mining

KG320 down the hole drill rig for open use is an improved device in compliance with national regulations on environmental protection. Equipped with the Yuchai engine (China 3), the drill rig meets national standards for emissions and environmental. 

The ramming motor of plunger piston and four-wheel drive improve the working pressure and climbing capacity. The expanded pith and lifting-arm hydraulic cylinder enable it to meet the requirements of limiting position use.

Meanwhile, the hydraulic system is improved, thereby proving increased system flow and rotary. The hydraulic cylinder has been optimized, thus making it more reliable. The guide rail is installed in an inclined way, making operations and observations easier. The thickened profile is used for the housing; and the additional ring makes handling and lifting convenient.
