Heavy-Duty Post Rammer & Rock Breaker – 7–9T Excavators
Dual-Function Tool | Mid-Size to Heavy Excavator Applications
Industrial-Grade Combination Tool for Post Installation & Breaking Work
The HFP Heavy-Duty Post Rammer & Rock Breaker for 7–9 tonne excavators is a dual-function hydraulic attachment engineered to deliver high-energy post installation alongside effective rock and concrete breaking capability in a single, robust unit.
Designed for civil works, fencing, utilities, rural infrastructure, site preparation, and demolition support, this attachment reduces attachment change-overs while delivering the impact energy required for harder ground conditions and heavier posts.
Built for Australian conditions, it is well suited to contractors, hire fleets, councils, utilities, and infrastructure 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 site efficiency by allowing multiple tasks to be completed with one attachment, reducing downtime and simplifying logistics.
With increased impact energy and operating weight, this model is suited to commercial fencing, civil construction support, and demanding site environments.
