  • Patent number: 7832975
    Abstract: A ramp system for a delivery vehicle for bridging a cargo bed of the vehicle and a ground surface. A series of ramps of the system are easily moved between a use orientation and a stowed orientation with the assistance of torsion springs of the system. The ramps are moveable for placement at various locations across the width of the vehicle and the selected location for use is locked so as to prevent widthwise movement of the ramps during use. No cargo area is used for stowing the ramps when not in use.

  • Patent number: 7310843
    Abstract: A ramp for use in bridging from a floor of an ISO standardized intermodal freight container to a placement pad on which the container is placed. An upper lip of the ramp is configured to engage with lower locking lugs of the container, which, although they are not covered by the standard, are found on most containers to be of similar design and located at substantially the same location on each container. The engaged upper lip of the ramp prevents movement of the ramp away from the container and in sideward directions to provide a safe surface for use by workers and equipment when loading or unloading the container.
