Germany’s Liebherr and Designwerk have developed the first fully electric concrete mixer trucks with 10- or 12-m³ drums on a five-axle chassis. The models are scheduled to premier later this year in Holcim and KIBAG fleets in Switzerland, where five-axle mixers with 40-tonne GVW are legal
The ETM 1005 and 1205 truck mixers bear on a Designworks Futuricum chassis. With equivalent 680 hp, they can transport large quantities of concrete quietly and reliably without diesel exhaust emissions.
An all-electric solution is particularly well suited for truck mixers, Liebherr notes: Vehicles return again and again to power infrastructure at the ready mixed plant, with battery charging typically an overnight process.
