<p>A shipping platform for transporting over-dimensional items, adapted for stacking above or below the decks of container ships on top of standard sized ISO cargo containers. The shipping platform has a base and foldable end frames. The shipping platform is wider than a standard ISO shipping container. The base has transverse end beams that are sufficiently rigid to allow the shipping platform to be mounted atop the corner posts of the standard ISO shipping container and support that portion of the shipping platform that extends beyond the width of the ISO shipping container.</p>
