Two latest generation straddle carriers, with a small diesel engine and Li-ion batteries, have gone into operation at HHLA Container Terminal Tollerort (CTT)
"The manufacturer Konecranes promises annual fuel savings of at least 15% per hybrid straddle carrier compared with the diesel-electric model most recently supplied to CTT," said HHLA. "This significantly lowers emissions. Konecranes forecasts an annual reduction of 30-50 tonnes of CO2 per straddle carrier."
The principle behind the hybrid technology is that the straddle carrier stores surplus energy, which is regenerated during braking or while the load is being lowered, in a high-performance lithium-ion battery. As it drives, the vehicle uses this energy from the battery. This significantly eases the load on the combustion engine.
Sustainability is a key component of HHLA’s corporate strategy. The company has set itself several a target of cutting CO2 emissions per container handled by 30% between 2008 and 2020 and says it already succeeded in bringing about a 28.9% reduction by 2017. This also includes using Konecranes Gottwald’s latest generation electric drive AGVs at Container Terminal Altenwerder.
