A concrete compactor arrangement, for compacting plastically deformable concrete in a shuttering (2), comprises several agitator units (1), fixed to the shuttering (2), each comprising a vibration generating device (3) and a vibration frequency controller (4). A set value for the vibration frequency of a vibration generated by the vibration generating device (3) is transmitted to a radio receiver (6), by a transmitter (7, 8, 9), each provided for one of the vibration frequency controllers (4). Each vibration frequency controller (4) is supplied directly by the mains network. Complicated control lines or lines for the transmission of the high frequency energy to the vibration generating device (3) can thus be avoided.
