  • Loading ramp device which rolls up for convenient storage
    Patent number: 6643878
    Abstract: A loading ramp structure is provided which is constructed out of a plurality of relatively small and rectangular links that are joined end to end to form a span of any desired length. The manner in which these links are joined together allows the span to be rolled up for storage when it is not in use and to be unrolled to form a ridged span when it is to be employed in the loading or unloading of wheeled load materials such as small supplementary vehicles.
