In January 2021, Liebherr-Transportation Systems was commissioned by Yarra Trams / KDR Victoria Pty Ltd., Melbourne (Australia) to supply rooftop air conditioning units for installation in Combino low-floor trams. The scope of delivery includes two replacement air conditioning units for the passenger compartment and three replacement units for the driver's compartment, which can be swapped for the units installed in the vehicles, which were also supplied by Liebherr, within a very short time during maintenance work. In this way, the maintenance-related downtimes of the fleet can be significantly reduced. Delivery is scheduled for the beginning of December 2021.
The Combino low-floor trams were developed and manufactured by Siemens AG. They are in operation in Melbourne for inner-city public transport since 2002.
