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, such as down the hole drilling, air/mud reverse circulation, cutting, cone, and pipe following drilling. The rig can install mud pumps, foam pumps, and generators as needed, and is equipped with various hoists.
Full hydraulic drive and top drive rotary propulsion deliver fast drilling speeds and short auxiliary times. Down the hole hammer drilling in rock yields high operation efficiency and lower single meter drilling costs.
The high outrigger is convenient for loading and transportation, allowing it to be loaded directly without a crane. Crawler walking is exceptionally suited for movement in muddy fields.
Features an efficient and durable oil mist device and pump. During drilling, the high-speed running impactor is continuously lubricated to greatly extend its operational lifespan.
Adjustable positive and negative axial pressure valves ensure that the impactor obtains optimal matching pressure and speed as the number of drill pipes increases, raising overall impact efficiency.
The drilling rig can be flexibly mounted on a crawler chassis, truck chassis, or trailer chassis to suit different mobility and transit demands.

The SNR1000 features a maximum drilling depth of up to 1000 meters (with the SNR1000C series supporting up to 1200 meters) depending on geological conditions.
It is designed for water wells, monitoring wells, ground-source heat pump air-conditioning engineering, blasting holes, bolting and anchor cables, micro piles, and other vertical drilling applications.
This versatile rig supports several methods, including down-the-hole (DTH) hammer drilling, through-air reverse circulation, air-lift reverse circulation, conventional circulation by mud, cutting drilling, cone drilling, and pipe-following drilling.
It allows for convenient rod changes and unloading of drill pipes, which reduces auxiliary operational time and facilitates efficient follow-up drilling.
To meet various terrain and transport needs, the drilling rig can be mounted on a crawler chassis, a truck chassis, or a trailer chassis.
As drill pipes are added, the weight and pressure increase. The adjustable positive and negative axial pressure valves allow the operator to balance force on the impactor to maintain maximum drilling efficiency.
