Komatsu Hybrid Excavator reduces fuel consumption and

CO2 emissions 

Komatsu’s Hybrid excavator system reduces fuel consumption and CO2 emissions through the use of an Ultra-Capacitor which captures kinetic energy when braking. The upper structure’s slew motion then reuses that energy to assist the next slew cycle, as well as delivering power to the engine.

The end result is fuel savings of 25-40% and savings on CO2 emissions, depending on application.
