The construction transport sector also faces the challenge of decarbonisation, and Bauma, the largest trade fair of its kind in Europe, will serve as the stage to showcase innovative solutions. On 24 February 2025, Renault Trucks revealed that it will introduce a fully electric concrete mixer at the event, built in partnership with Schwing Stetter on the E-Tech C10x4 chassis. Thanks to its five-axle configuration, the truck can carry up to ten cubic metres of concrete instead of the usual eight, despite the additional weight of the batteries.
Engineers have redesigned the vehicle’s architecture to ensure both manoeuvrability and efficiency. The vertical positioning of the batteries behind the cab has freed up space on the chassis, allowing for a shorter wheelbase and a reduced turning radius, a crucial feature for construction sites with restricted access and urban environments. Furthermore, improved load distribution ensures that axle weights comply with current regulations.
Schwing Stetter has developed a fully electric concrete mixer powered directly by the truck’s batteries, thereby eliminating CO2 emissions during operation. The vehicle has a range of 140 kilometres with an intermediate charge of 45 minutes or 110 kilometres on a single charge, enabling up to four daily trips of 35 kilometres – a typical distance between concrete plants and construction sites.
A key factor in the competitiveness of this solution lies in its energy management strategy. Renault Trucks assists customers in selecting the appropriate number of batteries and the optimal charging strategy, preventing oversizing that could reduce payload capacity and increase operating costs. The manufacturer states that, with the right configuration, the cost of transporting concrete is comparable to that of diesel models while complying with the most stringent environmental regulations.
The Renault Trucks E-Tech C 10x4 will initially be available in Switzerland, Ireland, the Netherlands, Luxembourg, Finland, Slovakia, and Lithuania, countries where legislation permits the use of five-axle trucks with loads of up to 42 tonnes.
