ABSTRACT:
Portable cargo loading apparatus capable of being placed into the hold of a ship for loading and unloading cargo respectively to and from the wing areas of the hold. Comprising the apparatus is a loading section formed of three large area relatively slidable trays arranged in a nesting relation capable of being power extended and retracted in a controlled operating sequence. During tray extension, cargo which has for example been delivered by a dockside crane directly into the uppermost tray is relocated by the apparatus from the delivery location for placement into a paired loading site within the wing. After loading of a localized wing site is completed, a transport section is operable to enable incremental lateral displacement of the loading section to a new paired location relatively juxtaposed to the wing site in which loading was just completed. Forming the transport section is a pair of spaced apart transversely extending and relatively displaceable beams of length at least twice the width of the loading section. An adjustment at each distal end of the beams enables the loading section to be elevated and laterally displaced along the beams to a successively new loading site. A power section including an electrical generator unit, pumps and controls enables the entire apparatus to be operatively self sufficient.
