The KG310/KG310H down the hole drill rig for open use is an improved device in compliance with national regulations on environmental protection. Equipped with the Yuchai double-cylinder engine (China III), the drill rig meets the national standards for emissions and environment. The flexible derricking mechanism is suitably qualified for horizontal drilling at a low level. 

The hydraulic system has been improved, leading to increased system flow and rotary speed. Moreover, the hydraulic cylinder has been optimized, thus making it more reliable; and the additional ring (plate) makes handling and lifting easier.

The KG310H down the hole drill rig for open use is equipped with a dust collector, thus making operation more environment-friendly and reliable.

KG320 down the hole drill rig for open use is an improved device in compliance with national regulations on environmental protection. Equipped with the Yuchai engine (China 3), the drill rig meets national standards for emissions and environmental. 

The ramming motor of plunger piston and four-wheel drive improve the working pressure and climbing capacity. The expanded pith and lifting-arm hydraulic cylinder enable it to meet the requirements of limiting position use.

Meanwhile, the hydraulic system is improved, thereby proving increased system flow and rotary. The hydraulic cylinder has been optimized, thus making it more reliable. The guide rail is installed in an inclined way, making operations and observations easier. The thickened profile is used for the housing; and the additional ring makes handling and lifting convenient.

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.

The KG430 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 the tramming motor of plunger piston improve the working pressure and climbing capacity.

The expanded pitch and lifting-arm hydraulic cylinder enable it to meet the requirements on limiting position. The double rotation motor increases the rotary toque 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 housing, thus improving its level of intensity and rigidity; and the additional ring makes handling and lifting convenient.
