Heavy-Duty Post Rammer & Rock Breaker – 5–6.5T Excavators
Dual-Function Tool | Mid-Size Excavator Applications
Industrial-Grade Combination Tool for Post Installation & Light-to-Medium Breaking
The HFP Heavy-Duty Post Rammer & Rock Breaker for 5–6.5 tonne excavators is a dual-function hydraulic attachment engineered to deliver high-energy post installation alongside light-to-medium rock and concrete breaking capability in a single, robust tool.
Designed for fencing, civil support works, utilities, rural infrastructure, and site preparation, this attachment reduces attachment change-overs while delivering substantially higher impact energy for larger posts and harder ground conditions.
Built for Australian conditions, it is ideally suited to contractors, hire fleets, councils, utilities, and specialist operators requiring a powerful, serviceable attachment for mid-size excavators.
Functional Overview
This attachment operates as both:
- a hydraulic post rammer for installing larger posts and pickets, and
- a hydraulic rock breaker for concrete, rock, and compacted ground preparation.
The combination design improves on-site productivity by allowing multiple tasks to be completed with one attachment, reducing downtime and simplifying site logistics.
With significantly increased impact energy compared to smaller models, this unit is well suited to commercial fencing, infrastructure support, and demanding site conditions.
