KG420 Crawler-mounted portable hydraulic cheap down the hole drilling rig for hard rock blasting
Application
The KG420 down the hole drill rig for open use is an improved device in compliance with national regulations in diesel-engine emissions. Equipped with Yuchai four-cylinder engine (China 3), the drill rig meets national standards for emissions and environment. The folding frame track, four-wheel drive and tramming motor of plunger piston improve the working pressure and climbing capacity, the expanded pith and lifting-arm hydraulic cylinder enable it to meet the requirements on extreme position. The double-motor rotation increases the rotary torque and revolving speed; and the lifting hydraulic 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.
