ELECTRIFICATION ELECTRIC AXLES
Also exhibiting its latest electrification technology at Bauma was Allison Transmission, a specialist in electrified vehicle propulsion for medium- and heavy-duty commercial vehicles. The company was showing the Allison eGen Power, an electric axle for construction applications, such as tipper trucks, concrete mixers and heavy duty tractors. The Allison eGen Power is a drop-in
component that is compatible with many existing truck chassis, helping OEMs to accelerate vehicle development. It features fully integrated electric motors, a two-speed gearbox, an integrated oil cooler and pump for optimal efficiency and performance and is compatible with battery
electric vehicles (BEV) and fuel cell electric vehicles (FCEV) as well as hybrids. There is also a twin-motor eGen Power
130D, a 13 tonne variant specifically designed for the European and Asia Pacific markets. This model has a continuous output of 454kW and a peak output power of 652kW, making it one of the most powerful electric axles on the market. It is designed for great starting and climbing capabilities, high speed and impressive efficiency. This allows heavy duty trucks to offer substantial performance and reliability, rapid acceleration and excellent manoeuvrability The eGen range of axles complements

developed by WAE would be integrated. A key element of the partnership is Liebherr’s ability to work in conjunction with WAE and FFI to develop electric battery and fuel cell systems that will be integrated into Liebherr’s T264 mining trucks. Liebherr’s partnership with both
WAE and FMG became a key part of Liebherr’s zero emission mining (ZEM) programme. The company’s trolley trucks and electric mining excavators already provide low and zero emission vehicles but Liebherr is nonetheless continuing to work within its zero emission mining programme so that by 2030 it will be able to provide complete mining systems for dozing, loading and hauling – all free of fossil fuels. Liebherr says that working with Tier 1 companies like WAE and FMG will ensure the deadline of 2030 is met. According to Dave Rawlins, head of Engineering Technology,

❱❱ WAE and Liebherr used the recent Bauma show in Munich to showcase their combined technologies
the existing range of TerraTran transmission products designed for the extreme demands of the global construction and mining markets but moves the company on to the important market of electric transmissions to meet the demanding net zero ambitions of the construction and mining sectors.
WAE, the partnership will enable customers, including FMG, to move towards net zero emissions through delivery and management of drive systems across the complete product life cycle. “We are delighted to be working on a strategic partnership with Liebherr to integrate zero emission drive systems into its products,” he says. During his conversations with
customers at Bauma, Bryant Ward of Liebherr discovered that many are aware of the urgency to adopt newer,
greener ways of doing things. He says that many customers know that they need to move to ZEM products but aren’t sure which direction to take. “With Liebherr having a clear ZEM strategy, they seem to have a
high level of confidence that we will achieve our targets and therefore are very interested in considering Liebherr for future purchases of equipment,” he says. T&TH
