The modifications comprise the provision of a smooth, solid, underplate at the lower extremity of the undercarriage of the material handling equipment item, and extending laterally beyond the undercarriage to provide a skid surface upon which the material handling equipment item may be supported on, and propelled across, the edges of an open top container and the contents of the container, and clamp members installed on outriggers of the material handling equipment item for engaging the sidewalls of an open top container to provide for positioning and support of the material handling equipment item on the container. The invention also includes method for conducting an unloading operation and for moving the equipment item from container to container.
