KG520/KG520H Down the hole Drill Rig, Designed for Large and Medium-sized Quarries and Contractors
The KG520/KG520H down the hole drill rig is designed for large and medium-sized quarries and contractors. The drill rig features a folding frame track and four wheel drive. The track leveling and plunger piston walking motor improve the working pressure and climbing capacity of the unit. The expanded pitch and lifting-arm hydraulic cylinder allow the equipment to meet limiting position requirements. The rotary torque and revolving speed are optimized and a propulsion motor and chain are used to raise the lifting force and reliability. The dust collector attached is enlarged to increase capacity. A thickened profile folder is used for the housing, thus improving its level of intensity and rigidity. The additional ring makes handling and lifting more convenient. We are confident that the drill can stand up to any task, including quarrying/mining and wall control.
