Operating weight
54,500kg
The largest of the GK line: 54.5 tonnes on the same Cummins X12, a 3.2 m³ standard bucket and 283 kN of bucket force. Twin-pump confluence matches different breaker sizes, so it doubles as a breaker carrier.
Low-speed, high-torque map with 23.8% more rated power and 14.3% more peak torque than the model it replaces.
Intelligent flow combining matched to breaker size: impact energy up, productivity up 20%.
Wear plates inside, thicker base and side plates and a deeper lip: reliability up 30%.
Roof and front guards for breaker duty, 140° rear camera and LED work lights.
