Komatsu HB365LC-3 Hybrid Hydraulic Excavator

The new HB365LC-3 Hybrid Hydraulic Excavator features an EU Stage IV engine and ultra-low noise levels, and it further reinforces Komatsu’s strong commitment towards a substantial reduction of the environmental impact of earthmoving machines. In Komatsu’s unique hybrid system, the electric swing motor-generator captures and regenerates energy as the upper structure slows down and converts it into electric energy. The regenerated energy is stored in the ultra-capacitor and used by the generator-motor to assist the engine when it needs to accelerate. Thus, the hybrid system reduces fuel consumption significantly.

Compared to a standard PC360LC-11 excavator, the HB365LC-3 Hybrid Hydraulic Excavator is designed to provide 20% fuel savings to customers. KOMTRAX™ data from HB365LC-3 machines working in Japan since February 2016 show that Komatsu has reached this target.
