Classification of shelf systems
- According to whether the shelf is fixed or mobile, it can be divided into:
(1) Fixed shelves: Fixed shelves can be subdivided into shelf type, tray type, through type, gravity type, press-in type, attic type, steel structure platform, cantilever type, mobile type, drawer type and corbel type shelf, etc. .
(2) Mobile shelves: Mobile shelves can be subdivided into mobile shelves and rotating shelves, of which mobile shelves can be subdivided into light and medium mobile shelves (also called dense shelves, divided into manual and electric), heavy duty Tray-type mobile shelves and rotating shelves can be subdivided into two types: horizontal rotating and heavy straight rotating shelves.
- According to whether the overall structure of the shelf is welded or assembled, it can be divided into:
(1) Welded shelves. (2) Assembled shelves. At present, most of the domestic use of assembled shelves.
- According to the connection between the shelf system and the warehouse building structure, it can be divided into:
(1) The rack-in-one shelf. The shelving system and the building roof constitute an inseparable whole. The shelf columns directly support the roof load, and the building envelope (wall) structure is installed on the columns on both sides.
(2) Separate structural shelves. The shelf system and the building are two separate systems with no direct connection to each other.
- According to the load capacity of each layer of the shelf, it can be roughly divided into:
(1) Light-weight shelves: the load capacity of each layer is not more than 200kg.
(2) Medium-sized shelves: the load capacity of each layer is 200~500kg.
(3) Heavy-duty shelves: the load capacity of each layer is above 500kg.
- According to the height of the shelf
(1) Low-level shelf: height below 5m.
(2) High shelf: height 5~12m.
(3) Super high shelf: more than 12m.
Third, the structural characteristics, application scope and selection principles of various shelf systems
- Shelf-type shelves.
(1) Light shelf shelf:
(2) Medium-sized shelf shelves:
(3) Heavy-duty shelving
