Seeking to deliver greater fuel efficiency in its line of earthmoving machines, Caterpillar Inc. has unveiled its first hybrid excavator, the 336E-H. The technology will pay back in as little as one year, the company says.
With an operating weight of approximately 40 tons, the excavator cuts fuel consumption by 25% over its non-hybrid counterpart, the standard 336E, and 33% over the outgoing model, the 336D, Cat says. Measured in tons of material moved per gallon, the hybrid excavator is 50% more fuel-efficient than the 336D.
