New Hybrid Excavator – up to 40% More Fuel Efficient
Komatsu America Corp. has introducted their new Hybrid PC200LC-8 excavator into the North American market. By developing a successful hybrid excavator in the largest construction machine segment (20-22 ton), Komatsu’s green technology will have a substantial impact on saving fuel and reducing green house emissions.
In tests comparing the standard PC200LC-8 hydraulic excavator to the Hybrid PC200LC-8, the hybrid model reduced fuel consumption by approximately 25 to 40%, depending on the application.
Substantial “green” impact
“Komatsu’s decision to apply its engineering excellence to the largest construction machine segment, clearly signals our commitment to developing environment-friendly equipment,” says Dave Grzelak, CEO and chairman of Komatsu America Corp. “Since the company’s inception, Komatsu has been setting the global standard for technology and engineering excellence and today that tradition continues with the introduction of the Hybrid PC200LC-8 excavator.”
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.
The innovative cab design assures operator comfort because the viscous cab damper mounts reduce vibration. A 18 cm LCD monitor provides easy-to-read gauges and onboard diagnostics as well as displaying the rear-view monitoring system for viewing the work area to rear of the machine.
KOMTRAX on board
The Hybrid PC200LC-8 excavator was introduced to the Japanese market in June 2008, and has been successful in reducing fuel consumption. In addition, Komatsu introduced the Hybrid to the Chinese market in August 2009.
