Kalmar launches the world’s first hybrid straddle carrier

By using the hoist motors as generators when lowering containers the energy produced is stored until it’s needed. Similarly, under braking or decelerating conditions, energy can be produced from the electric drive system and stored.

The machine’s supercapacitor energy storage system draws on the saved energy before making further demands on the diesel engine for movement or lifting, thereby drastically reducing fuel consumption and emissions.

An in-cab display shows the machine’s energy flow, thus the driving style can be further fine-tuned to make the most efficient use of the straddle carrier.
