Concrete vibrator for use in backpack and stationary configurations

A concrete vibrator comprising:

• a frame;
• a strap removably coupled to the frame;
• a main housing supported upon the frame;
• a motor housing pivotably coupled to the main housing about a pivot axis by a pivot joint, the pivot joint defining a passageway;
• an electric motor positioned in the motor housing;
• a flexible shaft having a first end coupled to the motor and an opposite, second end;
• a vibrator head coupled to the second end of the shaft, the vibrator head configured to receive torque from the motor and the shaft to cause the vibrator head to vibrate;
• a battery pack coupled to a battery receptacle defined on the main housing, the battery pack configured to provide electric power to the electric motor to drive the motor and the shaft;
• a remote control unit capable of adjusting operation of the motor to adjust a vibration frequency of the vibrator head;
• and
• an electrical wire routed through the passageway between the main housing and the motor housing, the electrical wire configured to transmit electrical current from the battery pack to the electric motor to drive the electric motor,
• wherein the concrete vibrator is operable in a backpack configuration in which the strap is used to carry the concrete vibrator with the frame in a vertical orientation, and in a stationary configuration in which the frame is supported on a surface in a horizontal orientation.
