KG420 Hydraulic Down The Hole Drilling Rig
KG420 Hydraulic Down The Hole Drilling Rig for open use is an improved device in compliance with national regulations in diesel-engine emissions. 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
KG420 Hydraulic Down The 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.
Specifiction
KG420 Hydraulic Down The Hole Drilling Rig often use a mud circulation system to cool the drill bit, carry cuttings to the surface, and provide stability to the borehole walls. The drilling mud is pumped down through the drill string and returns to the surface through the annular space between the drill string and the borehole.
These drill rigs are highly specialized and can vary in size and configuration depending on the specific application and geological conditions. They play a crucial role in various industries by enabling the extraction of valuable resources from beneath the Earth’s surface.
