HKM G280 Hydraulic Breaker
The HKM Grey Line Heavy Breakers are built for the harshest jobsite conditions - from quarrying and mining operations to high-tonnage demolition and infrastructure projects.
As the most powerful and largest model in the series, the G280 delivers extreme impact force, unmatched durability, and compatibility with a wide range of heavy-class excavators.
G280: THE LARGEST BREAKER IN THE GREY LINE
Powered by a hybrid gas-hydraulic power unit, the G280 operates efficiently across a wide range of pressure and oil flow conditions, ensuring fuel efficiency and flexibility.
The monoblock body design enhances structural strength and absorbs impact stresses, while extended wear plates and advanced damping systems reduce vibration and protect both the breaker and the carrier.
The optional automatic lubrication system extends component life and minimizes downtime.
For tunnel operations, the G280 features a specialized single-piece bushing design to reduce wear and lower consumable usage - even during intense vertical breaking.
Despite its weight and size, the G280 delivers consistent performance while protecting your investment in machines and manpower.

Frequently Asked Questions (FAQ)
Q: Is the G280 the biggest breaker in the Grey Series?
A: Yes, the G280 is the flagship model of the Grey Series, designed for heavy excavators between 34 and 55 tons.
Q: Is it suitable for quarrying?
A: Absolutely. With a massive 160mm tool diameter and 2850 kg weight, it delivers the high impact energy required for breaking hard rock in quarries.
Q: What is the "Monoblock Housing"?
A: It is a single-piece body design that eliminates tie rods (side bolts) in the housing structure. This makes the breaker more robust, durable, and resistant to the stresses of heavy-duty work.
