Patent ID: 8870197

Claim:
A portable apparatus for moving a vehicle across an area of ground comprising: a. a horizontal rigid platform having a front side, a back side, a left side, a right side, a top surface and a bottom surface; b. a lower plate placed under the horizontal rigid platform; c. a first tire roller having a first end and a second end rotatably supported on a left protruded portion extending from a left end of the front side; d. a second tire roller having a first end and a second end rotatably supported on a right protruded portion extending from the lower plate; e. a plurality of fixing means placed on the top surface to rotatably hold a first elongated shaft and a second elongated shaft; f. an electric power supply device for powering an electric motor coupled with the apparatus; g. a gear means interconnecting the electric motor and the first elongated shaft; h. a coupling means for connecting the first and elongated shaft to the second elongated shaft; i. a first joining means connecting the coupling means to a second joining means; j. a tension adjustment handle pivotally fixed to the horizontal rigid platform; k. wherein the electric motor is configured to rotate the first tire roller and the second tire roller resulting in lifting of the vehicle thereafter moving the vehicle; I. the horizontal rigid platform is supported by a plurality of casters; m. the lower plate is adjustable to move along the horizontal rigid platform; n. the first tire roller supported on the left protruded portion has a coarse grit on the outer surface; o. the second tire roller with the coarse grit on the outer surface is supported on the right protruded portion; p. the first tire roller and the second tire roller include a wheel guide on the first end and the second end; q. the first tire roller and second tire roller have a cylindrical body; r. the first tire roller and the second tire roller rotate about an axis passing through a center of the cylindrical body; s. the apparatus is configured to move the vehicle through rotation of a single tire of the vehicle; t. movement of the vehicle is accomplished when the apparatus is positioned so that the first and second tire rollers straddle the single tire of the vehicle; u. the electric motor powers rotation of the tire rollers in a desired direction thereby rotating the tire in the desired direction along the ground; v. the single tire remains in contact with the ground throughout the movement of the vehicle.
