Montabert CPA 30 150 Drilling Attachment

Overview of the Montabert CPA 30 150 Drilling Attachment

The Montabert CPA 30 150 is a carrier-mounted drilling attachment from the CPA (Carrier-mounted Percussion Attachment) range, designed to convert medium and heavy hydraulic excavators into autonomous, 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 30 150 is specifically engineered for hydraulic excavators in the 28–35 ton operating weight class. It is intended for demanding applications requiring extended drilling depth, high accuracy, and advanced automation, such as quarrying, trenching, pre-splitting, and ground reinforcement.
