The Komatsu Hybrid HB215LC-1 hydraulic excavator will be showcased at Bauma 2013. It is now available in Europe and worldwide, with more than 1900 Komatsu hybrid excavators owned by customers and millions hours of field operation logged in.
With an operating weight of 21.220 kg and bucket sizes ranging from 0.8 m³ to 1.05m³ the Komatsu HB215LC-1 fits into the large “21tonnes” class of hydraulic excavators and boasts an average of 25% less fuel consumption and CO2 emissions than a traditional
excavator. It’s a second generation hybrid machine and a product of groundbreaking research going back to the beginning of this millennium when Komatsu decided to develop hybrid technology for construction machinery to a level compatible with full scale serial production.
Cutting-edge technology
The HB215LC-1 offers to customers the benefits that make the Komatsu hydraulic excavators world renowned: low operating costs, first class operator comfort, highest safety standards and extreme reliability. The cabin, boom and arm, undercarriage and
revo frame, as well as the “Look and feel” of the new machine are practically identical as on a standard Komatsu PC210-8. Controls and wear parts are the same, making it simple for both owners and operators to profit from the added value of the HB215LC-1.
The HB215LC-1 is powered by the Komatsu Hybrid System, which includes Komatsu’s electric swing motor, power generator motor, capacitor and a 141 hp (104 kW) diesel engine. Komatsu developed its revolutionary hybrid system to work on the principle of
swing energy regeneration and energy storage using the Komatsu Ultra Capacitor system, which provides fast energy storage and instantaneous power transmission, thus significantly reducing fuel consumption.
The kinetic energy generated during the swing-braking phase is converted to electricity that is then sent through an inverter and captured by the Ultra Capacitor. This captured energy is discharged very quickly for upper structure rotation and to assist the engine as commanded by the hybrid controller when accelerating under workload conditions.
The hybrid components and the access to regular maintenance points were fine tuned on the HB215LC-1. Komatsu’s hybrid technology saves an average of 25% fuel with an equivalent reduction in CO2 emissions when compared to the standard excavator model.
The Hybrid HB215LC-1 offers power and efficiency along with a reduced environmental impact.
