Hybrid Excavator Will Save On Bottom Line, Too

摘要

As part of the ongoing development of a full-sized hybrid excavator, equipment manufacturer Doosan is now projecting a cost savings of $10,000 per month for future users of the machine.rnSlated for a North American launch in 2012, the 22-ton Doosan hybrid excavator will be equipped with a diesel engine, electric swing motor, electric converter, and an ultra-capacitor that will store excess energy during turning and light-duty operations. The reserve electricity will then be used to assist the power of the engine during heavier work, allowing the engine to maintain low revolutions and high-efficiency combustion during acceleration.
