Heavy-Duty Post Rammer & Rock Breaker – 10–12T Excavators
Dual-Function Tool | Heavy Excavator Applications
Industrial-Grade Combination Tool for High-Energy Post Installation & Breaking
The HFP Heavy-Duty Post Rammer & Rock Breaker for 10–12 tonne excavators is a dual-function hydraulic attachment engineered for high-energy post installation and effective rock and concrete breaking in a single, heavy-duty unit.
Designed for civil construction, utilities, rural infrastructure, fencing, site preparation, and demolition support, this attachment reduces attachment change-overs while delivering substantially higher impact energy for dense ground conditions and large posts.
Built for Australian conditions, it is ideally suited to contractors, hire fleets, councils, utilities, and infrastructure operators requiring a powerful, serviceable attachment for larger excavators.
Functional Overview
This attachment operates as both:
- a hydraulic post rammer for installing heavy posts and pickets, and
- a hydraulic rock breaker for concrete, rock, and compacted ground preparation.
The combination design improves site productivity by allowing multiple tasks to be completed with one attachment, reducing downtime and simplifying logistics on larger civil and infrastructure projects.
With significantly increased impact energy, this model is well suited to major fencing works, road projects, utilities installation, and infrastructure support tasks.
