Kaishan Surface Drilling Rigs/Mid-size Crawler DTH Drill Rig Series
KG726HIII
The KG726III/KG726HIII surface DTH drilling rig is an improved device in compliance with national regulations on environmental protection. Equipped with the Yuchai engine, the drill rig meets national standards for emissions and environment. The plunger-piston tramming motor 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 providing 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 KG726HIII surface DTH drilling rig is equipped with a dust collector, thus making operation more environment-friendly and reliable.
