The KG430/KG430H down the hole drill rig for open use is an improved device in compliance with national regulations on environmental protection. Equipped with Yuchai engine(China III), the drill rig meets national standards for emissions and environment. The tramming motor of plunger piston and four-wheel drive improve the working pressure and climbing capacity. The expanded pitch 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 speed. 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.

The KG430H down the hole drill rig for open use is equipped with dust collector, thus making operation more environment-friendly and reliable.
