DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a port arrangement for transfering first-type freight units, such as wheeled vehicles and goods on cargo pallets, and possibly second-type freight units, such as containers and general cargo or bulk cargo positioned on equivalent large-size pallets, on one hand, from a storage or storage area on shore into a freight space of a ship, and on the other hand, from the freight space into a storage or storage area on shore; the freight space of the ship comprising a first freight space compartment forming a structural part of the ship, said compartment comprising a plurality of superimposed freight planes intended for first-type freight units, and the ship hull including freight handling apertures for conveying freight units into the freight space of the ship, or out therefrom; in which port arrangement, first-type freight units are moved by means of a lifting framework from the storage or storage area through the freight handling apertures, and further, to be in each case at predetermined freight planes of the first freight space compartment, and along the freight planes to a desired location for transport, and from which freight planes the freight units are unloaded using reverse operations, and further, with the lifting framework into a storage or storage area, said lifting framework including a plurality of frame unit locations on one or more loading planes thereof. Specifically, the invention relates to a procedure and related arrangements for handling simultaneously at least two types of freight to be shipped in different ways, the first freight type thereof being usually cars or equivalent wheeled vehicles.
The scope of the invention described above comprises both freight types, but especially, as regards cars and other general cargo, simultaneous operations of a plurality of different handlings, and the matching thereof. Therefore, e.g. storing of cars and other general goods placed on pallets or equivalent bases, such as freight units, on shore, transfer from such storage or equivalent into a ship, and the transfers and positioning within the ship must be decided upon, and said different handling steps have to be linked together to be operative. Similarly, conveying freight units in the opposite direction from the ship into a storage on shore has to be organized. The corresponding operations have to be organized also for storing, transferring containers and general goods placed on large-size pallets, or potential bulk goods, and for other handling operations.
Conventionally, the cars and other wheeled vehicles are stored in ports on wide areas, by driving on their own wheels and using their own motors. For such storing, wide areas of land are needed, in order to accomodate all cars of one big, car-transporting ship in such area. Secondly, loading cars from such area into a ship, respectively, unloading from a ship on such area requires that each car be driven individually, which takes a lot of labour, is slow, and may involve costs if cars are damaged. Though, there are hardly any other type of arrangements available in the ports. In cities and towns a great number of multi-storey car parks may be available in which the cars are brought in or taken out by driving along ramps. Then, the land surface area can be reduced, but otherwise the handling of cars is very much the same as in land areas. Suggestions have been made to position cars in multi-storey car parks in the manner of automated warehouses, using lifts and lifting apparatus, as disclosed in GB-2 166 721, U.S. Pat. No. 2,916,166, and GB 380 711. By means of such arrangements, the positioning of cars can be mechanized in generally car-specific compartments or parking places in a multi-storey car park at least partly, but even with said arrangements, no sufficient efficiency in space utilization can be achieved, this being due to the reasons stated below. Lift or crane wells have to be positioned in frequency, so that any car can at any time be brought into the multi-storey car park or taken out therefrom. A parkin
