Montabert CPA 28 050 Drilling Attachment

Overview of the Montabert CPA 28 050 Drilling Attachment

The Montabert CPA 28 050 is a carrier-mounted drilling attachment from the CPA (Carrier-mounted Percussion Attachment) range, designed to convert medium and heavy hydraulic excavators into autonomous and high-performance drilling machines. As part of the CPA concept, drilling operations are carried out directly using the excavator, eliminating the need for a dedicated drilling rig.

The CPA 28 050 is specifically engineered for hydraulic excavators in the 28–35 ton operating weight class. It is intended for demanding construction, quarrying, and surface mining applications where extended drilling depth, stability, and continuous performance are required.

Main Advantages

• Designed for hydraulic excavators with an operating weight of 28–35 tons.
• Carrier-mounted CPA solution offering greater flexibility than conventional drilling rigs.
• Compatible with the Montabert HC50 hydraulic drifter.
• Allows drilling, anchoring, bolting, and blasting operations using a single carrier machine.
• Quick installation and removal, enabling efficient switching between excavation and drilling tasks.
• Reduces dependence on third-party drilling contractors and increases on-site autonomy.

Typical Applications

• Drilling for drill & blast operations in construction and quarry environments.
• Anchoring and mechanical or resin bolting.
• Surface mining and bench drilling.
• Civil engineering and large-scale infrastructure projects.
