ABSTRACT:
In a preferred embodiment, a system for unloading bulk material from a ship, which system includes: an elevating conveyor having a first, inclined section to raise bulk material from a lower space in the hull of the ship to a point above the deck thereof at the distal end of the elevating conveyor; the elevating conveyor having at the proximal end thereof a second section over which is disposed a single row of discharge gates generally parallel to the centerline of the ship and connected to the bottoms of a first plurality of hoppers which contain a first portion of bulk material, so as to selectively discharge the first portion onto the second section; cross conveyors to discharge a second portion of bulk material onto the cross conveyors; parallel conveyors generally parallel to the centerline to discharge the second portion onto the cross conveyors; each of the parallel conveyors being disposed underneath a row of discharge gates connected to bottoms of a second plurality of hoppers containing the second portion, so as to selectively discharge the second portion onto the parallel conveyors; and the cross conveyors being disposed at a location along the centerline between the first plurality of hoppers and the second plurality of hoppers.
