ST400 Pneumatic Borewell Machine advantage
Multi function drilling
Various drilling techniques can be used in such drilling machines, such as: drilling through hole, through air reverse circulation, air lift reverse circulation drilling, cutting drilling, gear drilling, pipe following drilling and core drilling under development. The drilling machine can install mud pump, foam pump and generator according to the needs of users. The rig is also equipped with various hoists as standard.
High efficiency
Because of the full hydraulic and top drive rotary propulsion, it is suitable for various drilling techniques and drilling tools. It is convenient and flexible to operate, and the drilling speed is fast and the auxiliary time is short, so the operation efficiency is high.
Low cost
The drilling technology of the hammer is the main technology in the rock drilling, and the drilling efficiency of the rock is high and the cost of single meter drilling is lower.
High leg track type
The high leg is easy to load and transport, and it is not necessary to load directly by crane. Crawler walking is more suitable for muddy field movement.
