China Suppliers Factory Well Drilling Rigs - Diesel Engine Driven Crawler Drilling Machines for Complex Terrain
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 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.
Wide 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 (FAQ)
What types of drilling techniques can be used with these drilling rigs?
These rigs support multiple drilling techniques, including submerged hole (DTH) drilling, mud drilling, tooth wheel drilling, casing/pipe following drilling, and core drilling.
How does the top-driven rotary propulsion system improve working efficiency?
The top-driven rotary propulsion and lifting system makes it convenient to load and unload drill pipes. This design minimizes auxiliary operation times and simplifies casing/pipe following drilling procedures.
Can the hydraulic operational parameters be adjusted during drilling?
Yes, the fully hydraulic system allows the drilling speed, torque, propelling shaft pressure, countershaft pressure, propelling speed, and lifting speed to be adjusted dynamically to suit different drilling tools and geological conditions.
What are the advantages of the crawler chassis and high outriggers?
The crawler chassis ensures stable movement across muddy and challenging construction sites. The high outriggers allow the rig to be loaded and transported directly onto vehicles without requiring a crane.
How does the oil mister function during rock drilling operations?
The oil mister lubricates the impactor during submerged hammer rock drilling. This lubrication significantly extends the service life of the impactor and reduces the operational cost per meter of drilling.
What projects are these drilling rigs commonly applied to?
They are widely applied in drilling water wells, testing wells, precipitation wells, rescue wells, ground source heat pump holes, coalbed methane extraction, natural gas, and oil extraction projects.
