Liebherr's first fully electric concrete mixer truck operates

The first fully electric mixer truck developed by Liebherr in cooperation with Design werk and ZF can carry 10 or 12 cubic meters of concrete on a five-axle chassis. Liebherr said that the equipment plans to deliver the first batch of products to Holcim and KIBAG customers in Switzerland in the fall of 2020.

The series are named ETM 1005 and 1205. The concrete mixer has a Design werk Futuricum chassis and a drive developed by Liebherr and ZF. The company said: "This is the first time that the automotive and truck manufacturing sectors are powered by traction batteries, thereby eliminating the need for expensive power electronic components." Among other things, this eliminates the need for expensive power electronic components.

The Futuricum chassis is equipped with a 500 kW electric motor, which, according to a Swiss manufacturer, exactly matches the weight of the concrete in the drum. The company did not provide information about the battery capacity of the transaction. However, due to the installation of two sets of batteries, they can provide guidance for other Futuricum vehicles with similar battery configurations. The Futuricum Collect 26E is an all-electric garbage collection vehicle with a power output of 500 kW, based on the Volvo FM series, which includes two 170 kWh batteries, which are provided by BMW.

The project sponsor stated that the mixer truck is particularly suitable for electrification because the distance from the concrete factory to the construction site is relatively shorter than the distance for freight. In cement plants, vehicles always return, so charging infrastructure can be installed and used for overnight charging. Swiss companies Holcim and KIBAG will now conduct actual tests on it. Liebherr said that this truck is very suitable for Switzerland. The Swiss 40-ton truck can run on five axles.
