Through shelf, also known as drive in shelf and corridor shelf, adopts pallet access mode, which is suitable for the storage of goods with few varieties and large quantities. On the support guide rail, the pallets are stored in the depth direction, one after another. The goods are stored and taken out from the same side of the shelf. The balance weight and forward moving forklift can easily drive into the middle of the shelf to access the goods without occupying multiple channels. As the forklift needs to access the goods inside the shelf, it is generally recommended that the depth of single-sided pick-up should not exceed 12 cargo spaces. In order to improve the operation speed of forklift, the guide track can be selected and configured according to the actual needs. It is suitable for warehouse design with low requirements for first in first out. It is widely used in cold storage, food and tobacco industries.   



   composition of through shelf   



  column, diagonal brace, cross brace, back pull, top pull, top cross beam, partition brace, double corbel, hanging plate, single corbel, foot guard, guide rail, etc.  



   features of through shelf:   



  1. On the support rail, the pallets are stored in the depth direction, one after another, which makes high-density storage possible.   



  2. Goods can be accessed from the same side of the shelf, stored first and then taken, and then stored and taken first. The counterweight and forward moving forklift can easily drive into the middle of the shelf to access goods without occupying multiple channels.   



  3. This kind of shelf is suitable for storing large quantities and few varieties of goods. The bracket and bracket shelf of the through shelf (drive in shelf) adopt the overall stamping / rolling technology, which has strong bearing capacity and beautiful appearance.   



   4 through type shelf is of full plug-in assembly structure, and the column is of assembly structure. The total depth of the shelf in the wall area is generally controlled within 5 tray depths, and the total depth of the shelf that can be accessed on both sides in the middle area is generally controlled within 10 tray depths, so as to improve the efficiency and reliability of forklift access.



   the stability of the through shelf system is relatively weak among all kinds of shelves. Therefore, the shelf should not be too high, generally within 10m. In addition, the system needs to be equipped with a pulling device. This system has dense shelf arrangement and high space utilization. It is suitable for storing a small variety of large quantities of goods of the same type. The goods can be stored and taken out from the same side or from one side to the other.



  the advantages of through shelf are:



   1. The cargo storage channel is also a forklift storage and transportation channel, which is a form of shelf with high storage density.  



   2. It is usually used for the storage of goods with few varieties but large quantities and low requirements for goods picking.  



   3. Based on the lifting height of ordinary forklift and the conventional scheme of three layers of goods in the corridor, the effective storage capacity of the warehouse can be increased by more than 100%. In contrast, the investment cost has been controlled and the benefit has been significantly improved. In terms of global storage cost, generally, the investment cost can be offset by the benefit of increased storage capacity within three years.  



  4. The goods follow the principle of first in and last out, which is applicable to the storage and transportation of most handling machinery.
