Kalmar introduces new hydraulic hybrid drive terminal tractor

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.”

Besides improving the fuel economy and reducing emissions, the optional hydraulic hybrid drive system allows enjoys smoother acceleration and the machine’s inching function also allows the vehicle to advance without engine power, further saving fuel and eliminating emissions altogether.

“Another significant advantage is the parallel system that allows the vehicle to function with or without its secondary power source. This feature further ensures the availability of the machine, not to mention its lack of downtime due to recharging,” added Vuojolainen,

The configuration of the hydraulic hybrid components allows for easy access and their scheduled maintenance intervals are twice as long as the intervals required to properly maintain a terminal tractor. In addition, the hybrid system does not require expensive replacement parts, helping to drive down the machine’s lifetime operating costs.

Committed to providing total support to its customers, Cargotec will conduct maintenance and operator training for customers’ own personnel, helping to further promote better fuel economy and machine reliability.
