Komatsu Europe International is presenting the new HB365LC-3, a 36 tonnes hydraulic hybrid excavator, at the bauma 2016 international fair in Munich.
Compared to a standard PC360LC-11 excavator, the new Komatsu Hybrid excavator was designed to provide 20% fuel savings to customers.
The HB365LC-3 has the same SAA6D114E-6 engine (202 kW/271 HP) as the PC360LC-11, with up to 53 kW extra electric power supplied by the Komatsu Hybrid system.
The kinetic energy generated during the swing-braking phase is converted to electricity, which is sent through an inverter and captured by the Komatsu Ultra Capacitor.
When accelerating under workload conditions the captured energy is discharged quickly for upper structure rotation and to assist the engine as commanded by the hybrid controller.
The reserve power stored by the hybrid technology represents additional horsepower that is available to maximize machine performance by supporting the engine, or is used for swing power.
