Product Description

The KG420B/KG420BH 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, the drill rig meets national standards for emissions and environment. The folding frame track and four-wheel drive are adopted; Add track leveling cylinders and the plunger piston tramming motor improves the working pressure and increase the rotary torque and revolving speed; and the lifting oil cylinder and chain are expanded to promote the lifting force and reliability. 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 KG420BH down the hole drill rig for open use is equipped with a dust collector, thus making operation more environment-friendly and reliable.
