The brushless generator converts rotational energy from the engine into alternating current electrical energy, and can also be driven as a motor to use recycled energy to drive hydraulics and save fuel, the company said.
The water-cooled inverter delivers electrical energy to the motor, while the water-cooled brake resistor passively consumes excess recycled energy.
Three electric cables manage all of the loader’s controls, Chesterman said during a media event at the World of Concrete show here. He also said that the constant engine speed helps extend engine life and reduce fuel consumption, while the electric motor cuts down on noise on the job.
He declined to discuss pricing, but did say that the hybrid 644K would sell “at a premium” to the standard diesel model.
