Montabert Micro CPA Drilling Attachment
Overview of the Montabert Micro CPA Drilling Attachment
The Montabert Micro CPA is a compact drilling attachment from the CPA (Carrier-mounted Percussion Attachment) range, designed to convert light hydraulic excavators into efficient drilling machines. Unlike conventional drilling rigs, CPA systems allow drilling operations to be performed directly using the carrier excavator, significantly increasing flexibility and on-site autonomy.
The Micro CPA is specifically engineered for installation on light hydraulic excavators in the 9–12 ton class, making it an ideal solution for contractors who require drilling capabilities without deploying dedicated drilling rigs.
Main Advantages
- Designed for light hydraulic excavators with an operating weight of 9–12 tons.
- Transforms a standard excavator into a versatile drilling unit without major machine modifications.
- Easy attachment and removal, allowing fast switching between excavation and drilling tasks.
- Improves excavator utilization by combining multiple functions on a single carrier.
- Reduces dependence on third-party drilling service providers and external equipment.
Typical Applications
- Anchoring and rock bolting using excavator-mounted drilling equipment.
- Drilling for drill & blast and pre-splitting operations.
- Trenching and ground reinforcement works.
- Dimensional stone and light quarrying applications.
- Urban construction, tunnelling, and confined or hard-to-reach job sites.
