HFP Heavy Duty Post Rammer & Rock Breaker | 0.8–1.2 Tonne Excavators | 25mm Pins

Industrial Grade Dual Function Post Rammer & Rock Breaker

The HFP Heavy Duty Post Rammer & Rock Breaker is engineered for 0.8–1.2 tonne excavators, combining post driving and hydraulic breaking capability in one compact, versatile attachment.

Designed for fencing, landscaping, civil works, utilities, property maintenance and construction applications, the attachment can be configured with the supplied 150mm post cup for post driving or one of the four supplied breaker tools for breaking concrete, rock and hard ground.

Combining two functions in a single attachment reduces the need for separate equipment and provides contractors with greater versatility from compact excavators, particularly when working in confined or restricted-access areas.

With a 40mm tool diameter, 180 Joule impact energy and 500–1000 BPM impact rate, the unit is designed to deliver dependable performance while maintaining an operating weight suitable for compact excavators.

Supplied complete with post cup, four breaker tools, hydraulic hoses and fittings, and backed locally by HFP Attachments with parts, repairs and ongoing technical support.
