BRIEF SUMMARY
TECHNICAL FIELD OF THE INVENTION
This invention relates to a method and arrangement for packing and producing cargo or shipping units of a number of smaller units, e.g. and preferably pieces of beef or other meat pieces.
BACKGROUND OF THE INVENTION
Meat such as so called quarter beef, i.e. fourth parts of a beef carcass, are today manually handled and carried from a land transporter, a truck or the like to shipping pallets where the beef pieces are stacked and subsequently wrapped or strapped.
The manual labor is extremely hard as each piece of meat weighs at least 100 kgs and often up towards 130 kgs. The meat pieces are frozen and they tend to get an exterior covering of ice or frost, which naturally makes the handling more difficult. Even if three or four men carry each piece, they are not able to stack such heavy pieces very high on a pallet, and the cargo thus placed on each pallet is normally rather low even if supporting uprights or frame elements are placed around the pallet.
BACKGROUND OF THE INVENTION
In sea transport it is an ambition to use the available hold space to the fullest extent and not only to fill the deck areas completely but also to fill the vertical space between the decks. On using manually stacked pallets as described above, the full vertical space can be utilized only if there are arranged rack or shelf systems between the decks so as to allow loading of two or more stacked meat pieces pallets the one above the other on each floor. Such systems involve a lot of extra work in installing and dismantling and hold up the loading and unloading as the rack sections adjacent the hatches normally have to be erected and dismantled respectively before the racks remote from the hatches can be loaded or unloaded.
One important object of this invention is to bring about a method and an arrangement permitting a practical utilization of the total available hold space without the need of rack systems or the like.
Another important object is to bring about a handling equipment minimizing the manual lifting and heaving and allowing stacking on pallets up to normal hold height thus enabling filling the hold to capacity with one layer pallets on each deck.
Still another object is to bring about a new system for securing the stacked load on the pallets.
SUMMARY OF THE INVENTION
The basic idea behind the invention is to take advantage of gravity on loading the pallets/and this is achieved by preparing a specific platform arrangement on a higher level than the pallet bottom level and placing the pallet inside a group of uprights serving as retainers for a stack of goods placed on the pallet, said uprights being secured to a base means, and arranging adjacent the said higher level receiving means for pre-loaded transport containers for the goods to be reloaded onto other pallets preferably shipping pallets, upon filling the space above the said pallet inside the uprights with goods, wrap a web of stretch film material around the pallet and the goods thereon outside the uprights and after wrapping such stretch film material around the goods stacked on the pallet, lift the pallet and stack of goods as one unit, leaving the uprights behind to slip by the sides of the stack and the inside of the wrapped film and subsequently transport the pallet and cargo unit for loading into a ship hold or the like.
