Definitions

• the present invention relates to the field of storing freight containers.
• it relates to a system for the storage and retrieval of freight containers and a method of carrying out the same.
• Containerisation is a system of freight transportation based on the use of freight containers.
• the containers are built to standardised dimensions in order to provide cross-compatibility across the various transportation networks such as road, rail and sea, for example.
• An example of international standards that are applicable to freight containers can be found in the International Standards Organisation (ISO) Handbook - Freight Containers (ISO 668:1995), which is hereby incorporated by reference.
• the ISO freight container is commonly twenty feet or forty feet in length. However, it is industry practice that the size of freight containers is often expressed in terms of twenty-foot equivalent units (TEU).
• TEU twenty-foot equivalent units
• PCT application published as WO 2010/087784 A1 discloses that one TEU container is generally 20 feet (6.1m) x 8 feet (2.4m) x 8.5 feet (2.6m) (length x width x height) in size (refer to [0002], lines 12 - 13).
• a further type of freight container typically referred to as a "High Cube" freight container.
• TEU container as disclosed in the Tan Patent and the High Cube container is that the height of a High Cube container is about 9,5 feet (approximately 2.9m).
• the High Cube containers are nevertheless also referred to as TEUs.
• a forty-foot container, or 2 TEUs has a length of 40 feet (12.2m) with the width and height of the container remaining the same as that of a single TEU (refer to [0004], lines 4 - 6 of the Tan Patent). It is this uniformity in the dimensions of the freight containers, insofar as the width and height are concerned, that allows the ISO freight container to be used widely across transportation networks as mentioned above. It is also this uniformity in dimensions that allows the freight container to be stored in a relatively compact manner by employing the practice of stacking.
• the Tan Patent also discloses that the freight containers are typically owned by a shipper, leasing lines, or a carrier (refer to [0005], line 13 of the Tan Patent). Often, after a freight container has been delivered to its destination and its contents unloaded, the freight container may not be required for further utilisation. In such instances, the freight container is sent to a container depot to be stored until required in the future. As container depots are shared facilities, i.e., several freight container owners share the storage facilities of the container depot, it is important that there is a proper management and tracking system in place to ensure that the location of each freight container is logged in order to facilitate any subsequent retrieval process in the event that the container is subsequently needed for use.
• a container depot also provides services and facilities for the repair and maintenance of freight containers. This includes welding, cutting, spray jet cleaning, painting and metal treatment for the containers (refer to [0005], lines 16 - 18 of the Tan Patent). Other services provided include the inspection and testing of the freight containers.
• a freight container stacker's cabin is situated at or around the 3' or 4 freight container in a stack, which results in difficulty for the operator of the container stacker when stacking freight containers above the height of the container stacker's operator's cabin, which in turn results in slower operations, when.
• the invention of the Tan Patent is intended to address the above-mentioned problems faced by freight container depots.
• the invention of the Tan Patent provides a building structure with a roof that is used for the storage of freight containers.
• the roof is also described as having container handling equipment, such as a crane, mounted thereon to hoist and store freight containers on the rooftop. Other equipment to be placed there includes forklifts and other stacking equipment.
• container handling equipment such as a crane
• each TEU could potentially weigh about 2,400kg when empty.
• each stack consisting of up to 10 containers, the cost of building a structure strong enough to withstand such a load factor will be prohibitive and cause freight container depot costs to be substantially higher as well.
• the invention of the Tan Patent contemplates using a crane, such as an overhead crane to stack the freight containers on the roof.
• a crane such as an overhead crane to stack the freight containers on the roof.
• the height to which containers may be stacked on the roof will be limited to the height of the overhead crane. In most cases, this will only permit stacks of 6 - 9 containers to be arranged. This limitation further prevents the number of freight containers that may be stored on the rooftop of the freight container depot and therefore results in a less than optimal use of the freight container depot disclosed in the Tan Patent.
