The structure of pallet shelf is similar to that of narrow aisle shelf, which is generally three or four layers. So the following will analyze the narrow aisle shelf and pallet shelf which is more advantageous.
Pallet racking (cross beam shelves) are generally similar to narrow aisle shelves. The basic structure of the shelf is similar. Because it is a storage shelf redesigned by the traditional cross beam shelf, the narrow aisle shelf integrates its basic structure and characteristics. The two kinds of shelves are generally operated by forklift, and each group of pallet positions of the two shelves are basically the same.
For what kind of pallets are used for cargo space loading, the two kinds of shelves have similar places in use, which should be determined according to the attributes of goods and the degree of containerization. As they are all heavy shelves, they are basically carrying out the warehousing activities of large goods such as industrial products, which have certain requirements for forklift operators and warehouse managers.
