China Suppliers Factory Direct Diesel Engine Drilling Rigs, Crawler Water Well & Mining Drilling Machines 200-1000m Depth
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 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
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 (FAQ)
What are the primary applications of these well drilling rigs?
These drilling rigs are highly versatile and 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.
What are the benefits of the fully hydraulic operation system?
The fully hydraulic design allows operators to adjust drilling speed, torque, propelling shaft pressure, countershaft pressure, and lifting speed at any time. This flexibility ensures compatibility with various drilling tools and different geological construction techniques.
What drilling methods can be performed with these rigs?
These rigs support multifunctional drilling techniques, including submerged hole (DTH) hammer drilling, mud drilling, tooth wheel drilling, pipe following drilling, and core drilling.
How does the top-driven rotary propulsion system improve efficiency?
The top-driven rotary propulsion and lifting system makes loading and unloading drill pipes highly convenient, which significantly reduces auxiliary operation times and simplifies pipe following operations.
Why is a high outrigger crawler chassis used?
High outriggers make loading and transportation easy, allowing the rig to be loaded directly onto transport trucks without requiring a crane. The crawler tracks ensure excellent mobility and stability on muddy or uneven jobsites.
What is the role of the oil mister on the drilling rig?
For rock drilling dominated by the submerged hammer process, the oil mister provides continuous lubrication to the impactor. This extends the service life of the impactor, maintains high drilling efficiency, and lowers the cost per meter.
