Development of New Hybrid Excavator. In order to make construction processes more efficient, a 6 ton class hybrid excavator was developed through a collaborative effort between KOBELCO CONSTRUCTION MACHINERY, Kobe Steel, and NEDO. Reductions in fuel consumption were evaluated through simulations on a series-type hybrid system.
Energy Storage: The accumulator stores and supplies energy required for various hydraulic functions, allowing the excavator to perform heavy-duty tasks efficiently. Smooth Operation: By absorbing pressure variations, the accumulator helps in maintaining a stable hydraulic pressure, resulting in smooth and precise movements of the machine.
