Komatsu America Corp. today announces the introduction of the Hybrid PC200LC-8 excavator into the North American market. Powered by the Komatsu Hybrid System, the Hybrid PC200LC-8 uses a newly developed electric swing motor, power generator motor, capacitor and 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. Komatsu’s Ultra Capacitors provide fast energy storage and instantaneous power transmission.
The kinetic energy generated during the swing braking phase is converted to electricity which is sent through an inverter and then captured by the Ultra Capacitor. This captured energy is then discharged very quickly for upper structure rotation and to assist the engine as commanded by the hybrid controller when accelerating under work load conditions.
In tests comparing the standard PC200LC-8 hydraulic excavator to the Hybrid PC200LC-8, the hybrid model reduced fuel consumption by approximately 25-40%, depending on the application.
The Hybrid PC200LC-8 is powered by the powerful, turbocharged and air-to-air after-cooled Komatsu SAA4D107E-1 which provides138HP. With an operating weight of 43, 643 to 47, 260 pounds, the Hybrid PC200LC-8 has a bucket capacity of 0.66 – 1.57 yd3. The Hybrid PC200LC- has the same vigorous working forces and performance levels of the conventional PC200LC-8.
The Hybrid PC200LC-8 is also equipped with the latest KOMTRAX® technology which sends machine operating information to a secure website utilizing wireless technology. Data such as operating hours, fuel consumption, machine location and machine utilization are relayed to the web application for analysis. The KOMTRAX fleet monitoring system increases machine availability, reduces the risk of machine theft and provides a wealth of other information to drive business efficiency.
