Komatsu Europe International presents the HB365LC-3, a high technology and environmentally sustainable 36 tonnes hydraulic hybrid excavator. It will be a highlight 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. Since 2008, when Komatsu commercialized the first hybrid construction equipment in the history of the industry, a total of 10,000,000 hours of operation have been registered by excavators benefiting from Komatsu‘s proven hybrid technology, which is today at work on over 3,500 units worldwide.
The new HB365LC-3 hybrid 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. It has the same SAA6D114E-6 engine (202 kW / 271 HP) as the PC360LC-11, with up to 53kW extra electric power supplied by the revolutionary 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.
The highly durable Komatsu-developed and manufactured hybrid components are covered by a “5 year or 10.000 hours” special warranty. All machine components and the EU Stage IV engine are optimally controlled to match the work at hand and are coordinated through Komatsu's total vehicle control system to deliver exceptional fuel savings and a reduced carbon footprint with no compromise on machine performance. As all Komatsu excavators, the new hybrid machine has a high lift capacity and great stability, and swing performance is fast and powerful. Oil flow is optimized for quick movement in combined operations for increased productivity.
