Abstract
An electrical drive device includes a hydraulic pump drive system for driving a concrete pumping system of a truck-mounted concrete pump. The hydraulic pump drive system includes a hydraulic pump, an electric motor, and at least two mains connection interfaces via which the electric motor is supplied with electrical energy. The electric motor is configured to drive the concrete pumping system. The mains connection interfaces are each assigned one or more mains connection modules. The mains connection modules each include a primary switched-mode power supply unit and are configured to feed a DC intermediate circuit via which the electric motor is connected.
