KG420/KG420H Down the hole Drill Rig for Open Use
The KG420/KG420H drill rig is a hydraulic, diesel powered, self-propelled down the hole rig, designed for open use drilling operations. Equipped with a Yuchai four-cylinder engine, the drill rig meets all relevant national standards for emission and environmental impact. It moves with a folding frame track and four-wheel drive. Added track leveling cylinders and a plunger piston tramming motor improve the working pressure and increase rotary torque and revolving speed. The lifting oil cylinder and chain are expanded to promote the lifting force with reliability. A thickened profile folder is used for the housing, thus improving its intensity and rigidity. The additional ring makes handling and lifting more convenient.
The KG420H down the hole drill rig for open use is equipped with a dust collector, thus making operation more environment-friendly and reliable.
