<p>CANADIAN PATENT APPLICATION OF CLAES NORDSTROM FOR GOODS-HANDLING METHOD AND APPARATUS FOR LOADING AND UNLOADING OF TRANSPORT VEHICLES This invention relates to a load-handling apparatus which is intended to be used for loading and particularly unloading of palletized or other goods which in relation to a base on which the goods are deposited, like the pallet of palletized goods, define at least one open-ended through channel of restricted width and height, and particularly for loading and unloading of such goods on road and rail vehicles, ships, aircraft etc. and also for loading and unloading of goods in large goods containers. Characteristic of the load-handling apparatus according to the invention is that it comprises at least two elongated, relatively narrow and long sections one of which forms a lower supporting section while the other forms an upper lifter and conveyer section raisably and lowerably mounted on the supporting section and parallel therewith and forming together with the first-mentioned section an elongated unit which is narrower than the open-ended through channel and which in the uppermost position of the lifter and conveyer section has a greater height and in the lowermost position of the lifter and conveyer section has a smaller height than the open-ended through channel, and a mechanism operating between the two sections, by means of which mechanism the lifter and conveyer section after insertion of the elongated unit beneath the goods is raisable relative to the supporting section resting on the same base as the goods to lift the goods for permitting conveyance of the goods along the lifter and conveyer section, the lifting mechanism permitting deposition of the goods by lowering of the lifter and conveyer section such that the elongated unit can thereafter be retracted from the goods. 1a</p> |
