Abstract
A portable backpack-borne power unit used for concrete vibration and consolidation, that is switchable between left-handed and right-handed applications. The power unit can transmit motor-generated power to a variety of tools with various power cables known in the art. For concrete vibration, power is transmitted to a vibrator that is immersed within green concrete. The instant design enables the power connection at the power unit to be secured on either side of the backpack, effectively facilitating either left-handed or right-handed operation.
