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.
Characteristics
KG series Blast Hole Drilling Rig for granite are specially designed drill equipment, which can be widely used for surface drilling such as quarry, railway construction, road construction, small to medium mining operation and etc. High performance features higher penetration rate with lower fuel consumption. Compressed air is used to operate crawler drill hammer for blast holes drilling, bench hole drilling, grout hole drilling, anchor hole drilling and etc.
