How Does the Hydraulic Drilling System Work?
The drilling process of the hydraulic core drilling rig machine begins when the engine supplies mechanical power to the machine’s hydraulic system. Hydraulic components then convert and distribute this power to the relevant mechanisms, supporting controlled movement and drilling operations.
During drilling, the drill string and compatible drilling tools penetrate the formation. The feed mechanism advances the drilling assembly, while the hoisting system supports lifting and lowering operations. Where required, a compatible mud pump circulates drilling fluid to help remove cuttings, cool the drilling tools, and maintain suitable borehole conditions.
The integrated ground-contact drilling system provides support during operation, while the selected transmission and hydraulic configuration help deliver the torque and feed performance needed for the application.
Actual drilling results depend on formation hardness, tool selection, borehole diameter, drilling fluid, operator experience, and site conditions. Correctly matching these factors to the selected rig is essential for achieving reliable performance.

Frequently Asked Questions
What drilling depth can this series achieve?
The supplied specifications list drilling depths from 200–400 meters for the YG-400 to 1,000–2,500 meters for the YG-2000. Actual achievable depth depends on ground conditions, borehole diameter, drilling tools, and operating configuration.
What is the difference between the seven models?
The models of the hydraulic core drilling rig machine differ in rated drilling depth, engine power, torque, hydraulic flow, hoisting configuration, mud pump capacity, dimensions, and machine weight. The best choice depends on your required depth and operating conditions rather than model number alone.
Can the rig drill through hard rock?
Suitability for hard rock depends on the rock’s strength and abrasiveness, the selected drill bit and core barrel, the drilling method, available torque, and operating parameters. Share your formation details and drilling requirements to determine a suitable configuration.
Is a mud pump included with the rig?
The supplied specification table lists mud pump models and capacities for the series. The exact pump supplied, included accessories, and optional equipment should be confirmed in the final quotation.
How can I select the right hydraulic core drilling rig?
Start with the target drilling depth, geological conditions, required borehole diameter, core sampling requirements, available site space, and transport limitations. Then compare the relevant models’ torque, hydraulic output, hoisting capacity, and supporting equipment.
