HKM GREY LINE HEAVY BREAKERS – G 230
The HKM Grey Line Heavy Breakers are engineered to handle the most demanding jobs — from quarry operations and large-scale demolition to heavy infrastructure and tunnel applications.
Among the flagship models of the series, the G 230 offers a powerful combination of high impact force, fuel efficiency, and long-term reliability for professional operators.
G 230: RELIABLE POWER FOR TOUGH CONDITIONS
Equipped with a hybrid gas-hydraulic power unit, the G 230 operates efficiently across a wide pressure and oil flow range.
This allows seamless compatibility with various excavator types and enables site-specific pressure tuning for optimized fuel savings.
Its monoblock housing design offers exceptional structural durability, while extended wear plates and advanced damping components significantly reduce vibration and noise — improving both operator comfort and equipment lifespan.
The automatic lubrication system, offered as an option, extends the service life of internal components and reduces maintenance downtime.
For tunnel environments, the G 230 includes a specially designed single-piece bushing system, minimizing wear and spare part consumption during vertical impact operations.
Despite its heavy-duty impact performance, the G 230 remains relatively lightweight for its class — making it suitable even for demanding vertical breaking tasks without overloading the carrier.
With its robust design and smart operational features, the G 230 is built to deliver consistent breaking power in the harshest jobsite conditions.
