Electric top-mounted systems for cement mixer trucks have been innovated to achieve fuel efficiency and significant reductions in carbon emissions by eliminating hydraulic transmission and adopting electric brake recovery technology, significantly reducing operating costs and minimizing environmental impact. This system improves transmission efficiency, reduces maintenance costs and extends engine life. Precise rotational speed control of the tank optimizes concrete quality and prevents segregation of the cement mix. These innovations not only save energy and protect the environment, but also guarantee the project quality, which represents a new development direction of cement mixer technology.
