Caterpillar Unveils Hydraulic Hybrid Excavator
Caterpillar Inc. has unveiled the first model in a new line of hybrid excavators. The Cat 336E H is the company's first machine to use a hydraulic hybrid technology developed internally by Caterpillar. Field tests have demonstrated this machine will significantly lower customers' owning and operating costs, the company said.
"The 336 excavator – a recognized industry-leading workhorse in our product line – made the most sense as our first choice for applying the unique hybrid technology," said Gary Stampanato, Caterpillar vice president with responsibility for the Excavation Division. "The new 336E H hybrid uses as much as 25% less fuel than the standard 336E without sacrificing performance."
The 336E H is designed to capture energy when the machine slows down or stops, and then releases it as the machine accelerates. On a typical job site, an excavator may repeat the same cycle every several seconds, which represents a significant energy savings opportunity, Cat said.
The official launch of the Cat 336E H is scheduled for April 2013 at bauma, the world's largest construction equipment show in Munich, Germany. Cat dealers will begin taking orders in February, with factory shipments beginning the following month.Edit Module
