Hybrid
Crawler Excavators

In Komatsu’s unique hybrid system, the electric swing motor-generator captures and regenerates energy as the upper structure slows down and converts it into electric energy. The regenerated energy is stored in the capacitor and can be used to swing, or by the generator-motor to help the engine accelerate. Thus, the hybrid system significantly reduces fuel consumption.
