Abstract
A concrete vibrator includes a housing, a handle, an electric motor, a flexible shaft, a vibrator head, and a battery pack. The handle extends from the housing. The electric motor is coupled to the housing. The flexible shaft has a first end coupled to the motor and an opposite, second end. The vibrator head is coupled to the second end of the shaft. The vibrator head is configured to receive torque from the motor and the shaft to cause the vibrator head to vibrate. The battery pack is coupled to a battery receptacle defined on the housing. The battery pack is configured to provide electric power to the electric motor to drive the motor and the shaft. The concrete vibrator is operable in a briefcase configuration in which the handle is used to carry the concrete vibrator with the housing supported in a horizontal orientation.
