Abstract
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.
Claims20
A method of loading a first a palletized stack of cartons 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 having
- a rotator and an elevator
- both of which being operably connected to the lift truck,
- the rotator having
- first and second sets of fork tines,
- the first set of fork tines having
- left and right fork tines,
- the second set of fork tines having
- left and right fork tines,
- the left fork tine from the first set of fork tines and
- the left fork tine from the second set of fork tines being
- opposed and
- capable of clamping onto said first palletized stack of cartons having said first height,
- the right fork tine from the first set of fork tines and
- the right fork tine from the second set of fork tines being
- opposed and
- capable of clamping onto said second palletized stack of cartons having a second height that is taller than said first height,
- wherein clamping can occur even where
- the second height is taller than in an initial position from the first height;
- (b) using the elevator of the rotating lift truck
- to elevate first and second palletized stacks of cartons of frozen animal products from said initial position and
- located in a first area,
- the first and second palletized stacks of cartons each having
- a pallet supporting a plurality of layers of cartons,
- each layer having a plurality of cartons;
- (c) using the rotating lift truck to simultaneously move
- the elevated first and second palletized stacks of cartons
- from the said initial position in the first area to a loading area for loading on a vessel lifting platform;
- (d) using the rotator of the rotating lift truck
- to rotate the elevated first and second palletized stacks of cartons 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 first and second palletized stacks of cartons towards to the vessel lifting platform,
- the vessel lifting platform being operably connected to the crane;
- and
- (f) the rotating lift truck loading the first and second stacks of cartons onto the vessel lifting platform.
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 having
- a rotator and an elevator
- both of which being operably connected to the lift truck;
- (b) using the elevator of the rotating lift truck
- to elevate said first and said second palletized stacks of cartons of frozen items located in a first area,
- the two palletized stacks of cartons having
- pallets 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 and
- the 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 cartons
- from 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 truck
- to 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 rotate
- the 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.
