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.
