Deep-Hole Drilling Rig Attachment, T6
Rock Drilling Attachment
The T6 deep-hole drilling rig attachment is a high-performance deep-hole drilling attachment specifically engineered for integration with excavators in the 20-ton class and above. Designed for precision drilling in complex geological environments, the T6 features a unique modular interface that allows for installation and operation without any modifications to the excavator’s original chassis or hydraulic system. This ensures versatility for the excavator.
The integrated automatic rod-handling system significantly accelerates the drilling cycle while eliminating the safety risks associated with manual handling. Whether tasked with hard-rock penetration or other demanding geological formations, the rig attachment provides a robust, efficient, and reliable solution for modern construction and mining operations.

- The drilling rig utilizes a specialized hydraulic distribution valve that enables seamless switching between excavator and drilling modes without any modifications to the original oil circuits. Utilizing a specialized hydraulic distribution valve, the drilling rig attachment enables rapid switching between excavation, drilling, and rock-breaking. The “plug-and-play” design allows for a true multi-functional machine with minimal downtime.
- Equipped with an automated hydraulic control system, the rig features load-sensing capabilities that automatically adjust drilling speed based on rock hardness. This intelligent adaptation maximizes efficiency while significantly reducing the failure rate of mechanical transmission components.
- The rig attachment leverages the excavator’s inherent 360° rotation and expansive arm reach to provide an unrestricted operating radius. This ensures high-performance drilling in complex geological strata with zero blind spots, making it an ideal solution for constrained or challenging construction environments.
The T6 deep-hole drilling rig is engineered for high-intensity performance across rock excavation and geotechnical projects. Its primary applications include blast-hole drilling, anchoring support, and mineral prospecting.
Beyond standard applications, the drilling rig attachment is highly effective in complex geotechnical engineering. It supports casing-advance drilling for hydropower cofferdam grouting, dam anti-seepage reinforcement, foundation stabilization, and specialized anchor hole construction.
