Fit for the future

MEILLER’s tipper bodies are compatible with all electric trucks from European manufacturers, regardless of whether they are already equipped with a mechanical power take-off (PTO) necessary for the superstructure’s hydraulics or an electric power take-off (E-PTO).

The electric drive offers a clear advantage: hydraulic systems can be operated according to demand, ensuring that the pump or hydraulics only run when the tipper body is in motion hence preventing unnecessary energy consumption.
