Caterpillar Cat 336E H

Caterpillar announces hybrid electric earth moving machine, Cat663E H

Heavy equipment maker Caterpillar proves that hybrid vehicle technologies can be applied big machines, as well as small, with introduction of a hybrid version of their industry-leading excavator machine.

On Wednesday, heavy equipment maker Caterpillar unveiled the Cat 336E H, a hybrid version of the Cat 336E earth mover. While it is a hybrid vehicle, it's not a typical tiny underpowered hybrid car, but a big beefy machine meant to move dirt, rock and other heavy loads at construction sites.

The primary goal is to use increased fuel efficiency to enable fuel savings lowering operating costs.

"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 percent less fuel than the standard 336E, without sacrificing performance. No other hybrid machine in its class in the market can achieve these dramatic savings. Since fuel is one of the largest operating costs for our customers in general, quarry and heavy construction applications, this is a technology that directly improves their bottom lines."

In Caterpillar's definition, a hybrid vehicle is equipped with a device to collect, store and release energy during machine operation. The 336E H is configured to capture energy when slowing down or stopping, and releasing that energy when the machine accelerates. In typical operation the machine will repeat this cycle over and over every several seconds, giving huge opportunities to save fuel. The drive train is a diesel-electric design but Caterpillar is not describing the electrical storage capacity nor power of the electric motor.
