Advantages of Pneumatic Drilling Rig:
- Top drive rotary propulsion lifting:
it is convenient for drill pipe loading and unloading, shortens auxiliary time, and is conducive to pipe following drilling.
- Multi functional drilling:
various drilling technologies can be used on this kind of drilling rig, such as DTH drilling, mud drilling, cone drilling, pipe following drilling and core drilling under development. Drilling rig can be equipped with mud pump, generator, electric welding machine and cutting machine according to user's requirements. The drilling rig is also equipped with various winches as standard.
- High operation efficiency:
due to the full hydraulic and top drive rotary propulsion lifting, it is suitable for various drilling technologies and drilling tools. It is easy to operate and flexible, with fast drilling speed and short auxiliary time, so the operation efficiency is high.
- Low cost:
DTH hammer drilling technology is the main method for rock drilling, with high efficiency and the lowest cost of single meter drilling.
Other features of Pneumatic Drilling Rig:
High outrigger crawler type:
the high outrigger is convenient for loading and transportation, and can be directly loaded without crane. The crawler type walking is more suitable for the muddy field movement.
Function of oil mist device:
DTH hammer drilling technology is mainly used in rock drilling. DTH hammer has high efficiency in rock drilling. The service life of the lubricated impactor is longer and the cost of single meter drilling is low.
Drilling rig chassis:
it can be a crawler type self-propelled chassis or a vehicle mounted self-propelled chassis.
application:
it is suitable for industrial and civil drilling and geothermal drilling. It has the advantages of compact structure, fast footage, flexible movement and wide application area. It is especially suitable for water intake in mountainous area and rock stratum.
