Dual-Function Tool | Compact to Mid-Size Excavator Applications

Industrial-Grade Combination Tool for Post Installation & Light Breaking

The HFP Heavy-Duty Post Rammer & Rock Breaker for 3–4.5 tonne excavators is a dual-function hydraulic attachment designed to deliver efficient post installation alongside light rock and concrete breaking capability in a single, robust tool.

Engineered for fencing, landscaping, utilities, trenching, and light demolition, this attachment reduces attachment change-overs while providing increased impact energy for heavier posts and firmer ground conditions.

Built for Australian conditions, it is suited to contractors, hire fleets, councils, utilities, and specialist operators requiring a versatile, serviceable attachment for mid-size excavators.


Functional Overview

This attachment operates as both:

  • a hydraulic post rammer for driving posts and pickets, and
  • a light-duty hydraulic rock breaker for concrete, rock, and hard ground preparation.

The combination design improves on-site efficiency by allowing multiple tasks to be completed with one attachment, reducing downtime and simplifying site logistics.

With increased impact energy compared to smaller models, this unit is well suited to commercial fencing and civil support works.
