The KG410/KG410H down the hole drill rig is particularly suited for operation in open pit mines and stone quarries. It comes equipped with a Yuchai four-cylinder engine (China III) and meets national standards for emissions and environmental impact. The folding frame track, four-wheel drive, and plunger piston tramming motor optimize the working pressure and climbing capacity of the machine. The expanded pitch and lifting-arm hydraulic cylinder allow the drill rig to meet the operating requirements in extreme positions. The double-motor rotation increases the rotary torque and revolving speed. The lifting cylinder and chain are expended to increase lifting force and reliability. The thickened profile folder is used for housing, thus improving intensity and rigidity. The additional ring makes handling and lifting more convenient.
The KG410H down the hole drill rig for open use is equipped with a dust collector, thus making operation more environment-friendly and reliable.
