　　The reason why many warehouses use high-rise shelves is to reduce floor space and improve warehouse utilization. This also means that the height design of the high-level shelves in the warehouse is very important. If the height is too high, it will cause problems with the flow of goods, and if the height is too low, it will waste storage space. So, what are the heights of high-level shelves?

　　Among many types of shelves, some are a few meters high, some are tens of meters high, and even tens of meters high. The different structures, heights, and adaptability determine their different uses. Generally speaking, we refer to storage shelves larger than 10 meters and above as high-rise shelves, which have unique advantages in large-scale and specialized warehousing operations in manufacturing and logistics transportation industries.

　　High rise shelving warehouses in foreign countries generally have a height of over 10m, with some reaching up to 30m. In China, it is generally above 10 meters, but currently most three-dimensional warehouses use high-rise shelves around 18 meters.

　　High rise shelves will not collapse due to excessive height, and the shelf area is fixed with dense expansion bolts. However, it is worth mentioning that the safety of high-rise shelves has always been criticized by warehouse management personnel. The following is a summary of the safety hazards and countermeasures of high-rise shelves:

　　1. Falling objects in the air: The height of the top fence crossbar of the high-rise shelves is above and below 40cm, which cannot completely block large volumes of goods. Improper placement of goods can lead to such hidden dangers. In addition, if the shelf height exceeds the normal height, the weight of stored goods will be large, and falling objects can cause casualties.

　　2. Accidental collision with shelves: During forklift operation, blind spots may appear, and dense pillars may block the view. Forklift workers may accidentally hit the safety stakes of the shelves, and if the safety stakes become loose over time, they may hit the pillars of the shelves.

　　3. Fire protection design is difficult and the fire protection effect is not good: the height of the shelves themselves almost occupies the height of the warehouse, and the coverage area of the top fire sprinkler is small, which poses a safety hazard.

　　4. There is no supporting forklift for operation: ordinary heavy-duty shelves will use forklifts to transport goods, while high-rise shelves will use standing forklifts to transport goods to higher places. However, forklifts are not produced in conjunction with the shelf factory, and their stability during use is poor, which can lead to spraying and easy tipping crisis.
