The XDX-2A full hydraulic core drill rig is mainly used for core drilling with a diamond bit or hard tungsten-carbide tipped bit. It is widely applied in industries such as geology, metallurgy, coal, nuclear energy, and hydrology.
Main Structural Features
- Hydraulic System & Chassis
- Equipped with a full hydraulic driving system.
- Mounted on a crawler chassis for stable mobility.
- Drill Head
- Top drive structure with speed adjustment.
- Lateral translation function.
- Two-gear stepless control for efficient drilling.
- Driven by a variable motor, ensuring high working efficiency.
- Mast
- Foldable design for easy transport and setup.
- Adjustable leg supports at the lower section.
- Upper mast can be fitted with extension joints when required.
- Hydraulic Clamp
- Positioned above the drilling hole.
- Includes a stabilizer for improved safety and reliability.
Upper mast can be fitted with extension joints when required.
Hydraulic Clamp
Positioned above the drilling hole.

The hydraulic chuck-type power head facilitates the extraction of the drill pipe. It reduces the probability of collapse and falling of the bottom of the hole, repeated breakage of the drill bit, and core blockage. The coring rate is high.
Wireless walking device can be installed optionally.

Ⅱ. Main Technical Features:
1. Full Hydraulic and Drill Head model. The drill head rotation is realized with four hydraulic pumps driven by diesel engine; this also makes the feeding hydraulic cylinder system realize its full stroke feeding in both higher and lower speed.
2. The rig can be applied and performed in narrow space for drilling of hole of 45-90° with stronger adaptability.
3. Strong techniques adaptability. Besides diamond drilling with wire line coring technique, it is in strong techniques adaptability. It is applicable for the drilling and feeding requirement of any other stratum.
Ⅱ. Main Parameters
The figures in these tables have been calculated, based on field experiences, and may be reasonably expected.
Actual drilling capacity will depend on in-hold tools and conditions, drilling techniques and equipment used.
