Montabert Micro CPA 360 Drilling Attachment

Overview of the Montabert Micro CPA 360 Drilling Attachment

The Montabert Micro CPA 360 is a compact drilling attachment from the CPA (Carrier-mounted Percussion Attachment) range, designed to convert light hydraulic excavators into flexible and fully autonomous drilling machines. As part of the CPA concept, it enables drilling operations to be performed directly from the excavator, eliminating the need for a dedicated drilling rig.

The Micro CPA 360 is specifically engineered for hydraulic excavators in the 10–14 ton class and features a 360-degree rotary drilling head. This design allows drilling and bolting operations in any direction, making the attachment particularly suitable for roof bolting, tunnel support, and work in confined environments.

Main Advantages

• Designed for hydraulic excavators with an operating weight of 10–14 tons.
• Equipped with a 360° rotary head enabling drilling and bolting in all orientations.
• Compatible with Montabert HC20 and HC25 hydraulic drifters.
• Transforms a standard excavator into a versatile drilling unit without major modifications.
• Quick attachment and removal, allowing efficient switching between excavation and drilling tasks.
• Improves excavator utilization while reducing reliance on external drilling contractors.

Typical Applications

• Roof bolting and ground support operations in tunnels and underground works.
• Anchoring and rock bolting using excavator-mounted drilling equipment.
• Drilling for drill & blast and pre-splitting applications.
• Ground reinforcement and trench drilling.
• Urban construction, tunnelling, and confined or hard-to-reach job sites.

Technical Specifications

Compatibility and Integration

The Montabert Micro CPA 360 is intended for light hydraulic excavators with sufficient hydraulic capacity and stability within the 10–14 ton range. Drilling operations are performed using Montabert HC20 or HC25 hydraulic drifters, ensuring compatibility with Montabert drilling systems, service components, and standard drilling consumables.

Thanks to its 360-degree rotary capability, the Micro CPA 360 enables drilling and roof bolting in positions that are not accessible with conventional fixed-mast attachments, making it a practical solution for tunnel support and confined-space applications.
