  • Patent number: 5782600
    Abstract: A cost-effective system and method for quickly and easily moving a fully loaded shelf unit is provided. The shelf unit includes first and second opposing vertical feet supporting the shelf unit on a ground surface. The system and method employ a first prying arm, a second prying arm, and a rolling device. The first and second prying arms each include a pushable member and a lifting member joined to each other. The rolling device includes first and second end supports and an intermediate cross bar extending between the end supports. The rolling device includes a pair of casters mounted to an underside of the cross bar for allowing the rolling device to be rolled along the ground surface. The end supports are located closer than the cross bar to the ground surface when the rolling device is positioned with its casters contacting the ground surface. To move the shelf unit, the prying arms are used to lift the respective vertical feet at least partially off the ground surface.
