SINOVO
1 / 2
Convenient and flexible adjustment. The speed, torque, thrust axial pressure, reverse axial pressure, thrust speed and lifting speed of the drilling rig can be adjusted at any time to meet the requirements of different drilling conditions and different construction technologies.
Highly advantageous design. It is convenient to take over and unload the drill pipe, shorten the auxiliary time, and is also conducive to follow-up drilling.
All kinds of drilling techniques can be used, such as down the hole drilling, through air reverse circulation drilling, air lift reverse circulation drilling, cutting drilling, cone drilling, pipe following drilling, etc. The machine can install mud pump, foam pump and generator according to users' needs. Equipped with a variety of hoists.
Suitable for all kinds of drilling technology and tools with convenient control, fast drilling speed, and short auxiliary time. The down the hole hammer drilling technology is the main method in rock, yielding high efficiency and lower single meter drilling cost.

The maximum drilling depth of the SNR200 hydraulic drilling rig is 240 to 250 meters, depending on the ground conditions and construction requirements.
It supports multiple drilling methods, including down the hole (DTH) drilling, through air reverse circulation, air lift reverse circulation, cutting drilling, cone drilling, and pipe following drilling.
Yes, it features a small body and a compact design, enabling it to be transported by a small truck, which saves transportation costs and makes it convenient to move in narrow grounds.
The SNR200 is designed for both unconsolidated formation and bedrock, making it versatile for various geological environments.
Yes, depending on users' needs, optional accessories such as a mud pump, centrifugal pump, generator, and foam pump can be integrated onto the rig.
The top drive rotary propulsion makes it highly convenient to take over and unload the drill pipe, which shortens auxiliary preparation time and assists in efficient follow-up drilling.
