A self propelled toolbox is provided with a plurality of storage compartments for storing tools. The toolbox is supported by two pairs of wheels. Each wheel of one of the pairs of wheels is a driven wheel that is mechanically coupled to an electric motor that causes the driven wheel to rotate about an axis to propel the toolbox. Each wheel of the other pair of wheels is a castor that is not operably linked to an electric motor and can pivot about an axis for steering the toolbox when the toolbox is in motion. The toolbox contains an energy reservoir in circuit communication with the electric motor for providing power to the electric motor. The quantity of power provided to the electric motor is controlled by a current controlling means that is accessible external of the toolbox by an operator of the self propelled toolbox. The two driven wheels may each be driven by the same electric motor, or they may each be driven by an electric motor that is mechanically coupled to only that wheel. |
