1, in the on the support the guide rails, the tray press the depth direction storage, an followed by one, which makes high-density storage become possible. 2. Access of goods same side enter and exit shelves after preexisting extraction, after Cun-xian extraction, counterbalanced and Reach truck conveniently 驶入 shelves 中间 access to goods, without seizing multiple channels. 3. This shelves for storing large quantities of less variety Racking (into the shelves) of corbels and corbels shelf adopt whole stamping / rolling technology, has strong bearing capacity, appearance goods. 4, through shelves full plug assembly structure, column pieces for assembly structure, total depth wall shelf area is generally the best control in less than five pallets depth on both sides of the intermediate region may total depth of the shelves and out of control is generally the best Within 10 trays in depth, to improve the efficiency and reliability of the forklift access. Stability through shelves systems are all kinds of shelves relatively weak, for shelves should not be too high, generally less than 10m, in addition the system still need to add Shiraz solid unit. Such a system shelf arrangement intensive, very high utilization of space, large quantities of varieties adapted to store less same type of goods, the goods can be removed from the same side deposit, but also would be transferred from one side other side removed.
