China Suppliers Factory: Diesel Engine Driven Crawler Water Well and Mining Drilling Rigs, 200-1000m Depth, 150-400mm Diameter
Fully Hydraulic Operation
The drilling speed, torque, propelling shaft pressure, countershaft pressure, propelling speed and lifting speed of the drilling rig can be adjusted at any time to meet the needs of different drilling tools and different construction techniques.
Top-Driven Rotary Propulsion
Top-driven rotary propulsion and lifting. It is convenient for picking up and unloading drill pipes, shortening the auxiliary time, and also favourable for following pipe drilling.
Multifunctional Drilling
All kinds of drilling techniques can be used on this drilling rig, such as: submerged hole drilling, mud drilling, tooth wheel drilling, pipe following drilling and core drilling which is under development and so on. The rig can be fitted with mud pumps, generators and welding machines according to customer requirements. The drilling rig is also equipped with various winches as standard.
High Operating Efficiency
Due to the full hydraulic and top-driven rotary propulsion lifting, adapted to a variety of drilling techniques and various drilling tools, convenient and flexible operation, fast drilling speed, short auxiliary time, and thus high operational efficiency.
Low Operational Cost
Drilling in the rock to submerged hammer drilling work metre drilling cost is low. Submersible hammer rock drilling has high operational efficiency and low drilling cost per metre.
High Outrigger Crawler Type
High outriggers are convenient for loading and transporting, and can be loaded directly without a crane. Crawler walking is more adaptable to move in the muddy site.
Role of Oil Mister
Drilling in the rock is dominated by the submerged hammer drilling process, the submerged hammer rock drilling operation is highly efficient, the lubricated impactor has a longer service life, and the cost of drilling per metre is low.
Drilling Rig Chassis
It can be tracked self-propelled chassis or vehicle-mounted self-propelled chassis.
Widely Used Applications
Widely used in drilling water wells, testing wells, precipitation wells, rescue wells, ground source air-conditioning holes, coal bed methane, natural gas, oil extraction and other projects.

Frequently Asked Questions
1. What drilling techniques can be used with these drilling rigs?
These drilling rigs support a wide variety of drilling techniques, including submerged hole (DTH) drilling, mud drilling, tooth wheel drilling, pipe following drilling, and core drilling (under development).
2. How does the fully hydraulic operation system benefit drilling operations?
The fully hydraulic operation allows you to adjust the drilling speed, torque, propelling shaft pressure, countershaft pressure, propelling speed, and lifting speed at any time. This ensures adaptability to different drilling tools and construction techniques.
3. What are the advantages of the top-driven rotary propulsion system?
The top-driven rotary propulsion and lifting design makes it highly convenient to pick up and unload drill pipes. This significantly shortens auxiliary operation time and facilitates following-pipe drilling.
4. Why do these drilling rigs offer low operational costs?
The combination of highly efficient submerged hammer rock drilling and an integrated oil mister (which lubricates the impactor to extend its service life) ensures that the drilling cost per meter remains low.
5. What chassis configurations are available for these rigs?
The rigs can be configured with either a tracked self-propelled crawler chassis (highly adaptable for moving in muddy sites) or a vehicle-mounted self-propelled chassis, depending on your transportation and job site requirements.
6. What projects are these drilling rigs typically used for?
These rigs are widely used for drilling water wells, testing wells, precipitation wells, rescue wells, ground source air-conditioning holes, coal bed methane extraction, natural gas, and oil extraction projects.
