​Hybrid Performance
​In the latest construction machine segment (20-22 ton) Komatsu’s green technology will have a substantial impact on saving fuel and reducing greenhouse emissions. The Komatsu Hybrid HB205-1 Excavator delivers a machine with power and efficiency, while reducing environmental impact as compared to conventional models.
The Hybrid HB205-1 is powered by the low emissions turbocharged and air-to-air after cooled Komatsu SAA4D107E-1 diesel unit, which provides 138 HP, with an operating weight of 20, 900kg to 21,437 kg. Bucket capacity is 0.5 - 1.2m3
In construction equipment, the energy demand is high and occurs in a short timeframe. Combined with a high frequency of demand, the electrical energy requirement to operate construction equipment cannot be met with current battery technology.
The ‘Komatsu Hybrid System’ uses the Ultra Capacitor to instantaneously store and give off electrical energy efficiently. The capacitor charges and discharges in a much faster method than the slower chemical reactions that take place in batteries.

The high energy demand and frequent cycles needed by an excavator are matched by the instantaneous charging and discharging characteristics of a capacitor. You can expect the same level of productivity from the Hybrid as the conventional PC200LC-8.
But, the technological innovation does not stop here. The Hybrid HB205-1 also boasts the latest KOMTRAX® system – relaying real time operating data to the vehicle owner / manager. The KOMTRAX® fleet monitoring system increases machine availability, reduces risk or theft and provides a wealth of important operating data that helps drive business efficiency.
The Komatsu Hybrid Excavator is the most complete package available to the industry. Delivering 25% - 41% less fuel consumption than conventional excavators on jobsites around the world and significantly lower CO2 emissions. Hybrid operators have experienced emission reductions of as much as 10 kg per hour of operation.
