ABSTRACT:
A system for loading and unloading a barge. The system includes two gantry assemblies, one for loading and one for unloading. The gantry assemblies are mounted on tracks for traversing the length of the barge. One gantry assembly has a hopper for receiving material and a movable conveyor for distributing the material across the width of the barge. The barge is moved relative to the docking site and the gantry is moved relative to the barge to maintain the gantry in position relative to loading equipment. The second gantry assembly is used to unload cargo from the barge. The second gantry has dual pick up conveyors for elevating the material onto a conveyor system which transports the material to a receiving site. The second gantry is moved along the length of the barge to remove the material in layers. Material is removed as the gantry moves in each direction.
