Abstract:
A rolling vehicle jack for elevating a vehicle includes a base. A spring is coupled to a top of the base and is positioned in an internal space of the base. A sphere is rollably coupled to the spring and selectively extensible through a penetration that is positioned through a bottom of the base. A lift is coupled to and selectively extensible from the top of the base. An actuator, positioned in the internal space, is coupled to the base and operationally coupled to the lift. The sphere is configured to roll on a surface such that the base is reversibly positionable under a vehicle. The actuator is positioned to motivate the lift to extend vertically from the base, wherein the sphere is retracted into the base. A vehicle that is positioned above the lift is raised and is positioned for maintenance, such as changing of tires, wheels and tracks.
