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.
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 on this kind of drilling machine, 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 drilling machine can install mud pump, foam pump and generator according to the needs of users. The rig is also equipped with a variety of hoists to meet the different needs of customers.
Due to full hydraulic drive and top drive rotary propulsion, it is suitable for all kinds of drilling technology and drilling tools, with convenient and flexible control, fast drilling speed and short auxiliary time, so it has high operation efficiency. The down the hole hammer drilling technology is the main drilling technology of the drilling rig in the rock. The down the hole hammer drilling operation efficiency is high, and the single meter drilling cost is lower.
The high outrigger is convenient for loading and transportation, and can be loaded directly without crane. Crawler walking is more suitable for muddy field movement.
Efficient and durable oil mist device and oil mist pump. In the process of drilling, the high-speed running impactor is lubricated all the time to extend its service life to a greater extent.
The best impact efficiency of all kinds of impactors has its best matching axial pressure and speed. In the process of drilling, with the increasing number of drill pipes, the axial pressure on the impactor is also increasing. Therefore, in the construction, the positive and negative axial pressure valves can be adjusted to ensure that the impactor can obtain more matching axial pressure. At this time, the impact efficiency is higher.
The rig can be mounted on crawler chassis, truck chassis or trailer chassis.

The SNR1000C water well drill rig is designed to achieve maximum drilling depths of up to 1200m (with a standard rating of 1000m depending on actual geological conditions and site requirements).
This multifunctional drill rig is designed to handle multiple drilling methods including reverse circulation by mud and by air, down the hole (DTH) hammer drilling, and conventional circulation.
The top drive design makes the coupling and uncoupling of drill pipes much more convenient. This significantly reduces auxiliary operational times and enhances follow-up drilling efficiency.
As drill pipes increase during deep drilling operations, the axial load increases. Operators can adjust the positive and negative axial pressure valves to match the optimal requirements of the DTH hammer, achieving maximum impact efficiency.
To meet diverse transport and terrain needs, the rig can be mounted on a crawler chassis, a truck chassis, or a trailer chassis. A high outrigger configuration is also available for crane-free self-loading.
The rig is equipped with an efficient, durable oil mist device and oil mist pump, which ensures the high-speed running impactor is consistently lubricated throughout the drilling process, extending its overall service life.
