The hybrid technology package is a modular option that can be fitted to the latest ESC W straddle carriers and results in fuel savings of up to 25 or 30%. By delivering more moves with less fuel, Kalmar estimates that this new technology can eliminate more than 50 tonnes of CO2 emissions per straddle carrier per year.
Kalmar’s Pro Future(tm) hybrid technology package allows hoist motors to be used as generators when lowering containers. The energy produced can be stored until it’s needed. Similarly, when machines are braking or decelerating, energy can be drawn from the electric drive system and stored. The machine’s supercapacitor energy storage system uses 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.
All six TCS straddle carriers will incorporate a VSG (Variable Speed Generator) diesel-generator package with temperature-controlled fan technology which monitors engine use, determining whether high or low engine power is needed. By automatically matching power output to demand, fuel consumption is reduced with a resultant lowering of exhaust emissions
TCS currently operates a fleet of 39 modern electric and diesel straddle carriers, which will be expanded with the latest Kalmar equipment.
