A method and apparatus for rapid loading stacks of items aboard vessels which can include rotating palletized items to depalletize the items, and then placing the items on a lifting robot, lifting the robot and items into the hold of a vessel, removing the items from the robot using a load push lift truck, and then using the load push lift truck to stow the items in a stowage location. The empty robot can be removed from the hold of the vessel and put in a position to receive a another depalletized stack of cartons. In one option the robot has a plurality of fork channels for receiving the blades of a load push lift truck along with receiving the blades or a rotating lift truck.

The method of claim 1, wherein the pallets are not raised with the vessel lifting platform. 3. The method of claim 1, wherein the rotator includes first and second opposed sets of fork tines, the first and second sets of fork tines clamping on the first and second palletized stacks of cartons in step “d” during rotation. 4. The method of claim 1, wherein the rotator includes first and second sets of opposed fork tines, the first set of fork tines being inserted into the pallets in step “b”, the first and second sets of fork tines clamping on the first and second palletized stacks of cartons in step “d” during rotation, and the first set of fork tines being used to space apart the pallets from the cartons before step “d.” 5. The method of claim 1, wherein the rotator includes first and second sets of opposed fork tines, the first set of fork tines being inserted into the pallets in step “b”, the first and second sets of fork tines clamping on the first and second palletized stacks of cartons in step “d” during rotation, and the first set of fork tines being used to space apart the pallets from the cartons after step “d.” 6. The method of claim 1, wherein the rotator includes first and second sets of opposed fork tines, the first set of fork tines being inserted into the pallets in step “b”, the first and second sets of fork tines clamping on the first and second palletized stacks of cartons in step “d” during rotation, the second set of fork tines being used provide support for the stacks of cartons after step “d”, and the first set of fork tines being used to space apart the pallets from the stacks of cartons before step “d”. 7. A method of loading a first a palletized stack of cartons with frozen items of a first height and a second palletized stack of cartons of a second height from an initial rest position in a first area onto a vessel with a hold and a lifting crane, the method comprising the steps of: (a) providing a rotating lift truck, the lift truck havinga rotator and an elevatorboth of which being operably connected to the lift truck;(b) using the elevator of the rotating lift truckto elevate said first and said second palletized stacks of cartons of frozen items located in a first area,the two palletized stacks of cartons havingpallets supporting a plurality of layers of cartons,each layer having a plurality of cartons of frozen items,the first stack having a first height in an initial rest position in said first area andthe second stack having a second height that is taller than the first height in said initial rest position,(c) using the rotating lift truck to move the elevated stack of cartonsfrom the initial rest position in the first area to a loading area for loading on a vessel lifting platform,the lifting platform being operably connected to the crane;(d) using the rotator of the rotating lift truckto clamp both the first palletized stack of cartons of the first height and the second palletized stack of cartons of the second height and then rotatethe elevated first and second stacks of cartons and pallets by at least about 180 degrees in a first direction,(e) during at least part of step “d”the rotating lift truck moving the elevated stacks of cartons towards the vessel lifting platform; and(f) using the rotating lift truck to load the stacks of cartons on the vessel lifting platform. 8. The method of claim 7, wherein the pallets are prevented from being raised with the vessel lifting platform, and the rotating lift truck includes a rotation stop which automatically restricts the extent of rotation to about 180 degrees in the first direction. 9.
