Kalmar introduces new hydraulic hybrid drive terminal tractor

The new machine is equipped with a parallel system that simultaneously transmits power from two distinct sources – the primary diesel engine and the secondary hydraulic motor. The coordination of these power sources maximises fuel economy and satisfies performance constraints.

Although fuel consumption with the hydraulic hybrid system can vary depending on driving style and the operational application, in the typical port environment, fuel savings of 20% and an even greater reduction of NOx and particulate matter emissions can be achieved.

The pressure to reduce emissions at ports and in urban areas is strongest in the US. “Companies operating large fleets of equipment in confined spaces, often near urban developments, can come under significant pressure to reduce their environmental footprint,” said Mikko Vuojolainen, VP Terminal Tractor. Moreover, with the number of machines involved in normal port operations, “any fuel savings per machine can translate into significant savings when applied to a whole fleet.”
