This solution is designed for use with medium/large mixer trucks that have medium/long delivery distances to travel. Drum rotation speed is between 15 and 22 rpm and capacity between 6 and 14 m3.
Bonfiglioli innovative solution comprises a gearbox of Bonfiglioli’s historical 500 Series coupled to an AC electric motor that provides normal power and a DC electric motor for emergency use.
This solution not only guarantees greater energy efficiency and reduced fuel consumption, but also helps cut cement mixer truck operating costs (for example by extending service intervals and making servicing simpler than on hydraulic drive solutions). Performance is improved too: rotation speed control is more accurate, operating noise levels are significantly lower (thanks to the electric motor and the helical tooth profile of the high speed gearbox stage).
Finally, functionality remains higher in the event of a failure: the presence of a second, backup DC motor gives reassuring redundancy a
