The KG520/KG520H down the hole drill rig for open use is an improved device in compliance with national regulations on diesel-engine emissions. Equipped with the Yuchai four-cylinder engine (China III), the drill rig meets national standards for emissions and environment.
The KG520/KG520H down the hole drill rig for open use is an improved device in compliance with national regulations on diesel-engine emissions. Equipped with the Yuchai four-cylinder engine (China III), the drill rig meets national standards for emissions and environment. The folding frame track and four-wheel drive are adopted; and track leveling and the walking motor of plunger piston improve the working pressure and climbing capacity. The expanded pitch and lifting-arm hydraulic cylinder enable it to meet the requirements of limiting position. The rotary torque and revolving speed are raised; the propulsion motor and chain are used to raise the lifting force and reliability. The dust collector is enlarged to produce a better effect on dust collection. The thickened profile folder is used for the housing, thus improving its level of intensity and rigidity; and the additional ring makes handling and lifting convenient.
The KG520H down the hole drill rig for open use is equipped with a dust collector, thus making operation more environment-friendly and reliable.
