Komatsu Europe introduces new 36t hydraulic hybrid excavator; 20% fuel savings

Komatsu Europe International has introduced the new HB365LC-3, a 36-tonne hydraulic hybrid excavator. Compared to a standard PC360LC-11 excavator, the new Komatsu Hybrid excavator provides a 20% fuel savings.


The HB365LC-3 has the same EU Stage IV SAA6D114E-6 engine (202 kW / 271 HP) as the PC360LC-11, with up to 53kW 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 an ultracapacitor bank. 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.

The hybrid components are covered by a 5-year or 10,000-hour warranty.

Komatsu’s new EU Stage IV engine integrates SCR to further reduce NOx emissions using the AdBlue additive. Komatsu continues to use a Komatsu Variable Geometry Turbocharger (KVGT) and an Exhaust Gas Recirculation (EGR) valve for precise temperature and air management control and for longer component life.

Komatsu commercialized the first hybrid construction equipment in 2008l since then Komatsu’s hybrid excavators have logged a total of 10,000,000 hours of operation.
