3. According to the connection between the shelf system and the warehouse building structure, it can be divided into

(1) the storage rack is composed of shelves

The shelf system and the building roof form an integral whole, the roof load is directly supported by the shelf columns, and the building envelope (wall) structure is installed on the columns on both sides.

(2) separated structure shelf

The shelf system and the building are two separate systems without direct connection with each other.

4. The load capacity of each layer of the connected unit shelf can be roughly divided into

(1) light shelf: the load capacity of each layer shall not be greater than 200kg.

(2) medium shelf: the load capacity of each layer is 200 ~ 500kg.

(3) heavy shelf: the load capacity of each layer is more than 500kg.

5. According to the height of the shelf

(1) low shelf: height below 5m.

(2) high shelf: 5m ~ 12m high.

(3) super high shelf: more than 12m.

3、 Structural characteristics, application scope and selection principle of various shelf systemsShopping Trolley manufacturer

1. Shelf type shelf

Shelf type shelves are usually manual goods access, assembled structure, uniform and adjustable layer spacing, goods are often bulk or not very important packaged items (convenient for manual access), and the shelf height is usually less than 2.5m, otherwise it is difficult to reach manually (it can be set at about 3M if supplemented by climbing car). The span (i.e. length) of the unit shelf should not be too long, and the depth (i.e. width) of the unit shelf should not be too deep. According to the load weight of each layer of the unit shelf, it can be divided into light, medium and heavy shelf shelves, and the laminates are mainly steel laminates and wood boards.Shopping Trolley manufacturer

(1) light shelf: the load capacity of each layer of unit shelf shall not be greater than 200kg, and the total load capacity is generally not greater than 2000kg. The span of unit shelf is usually no more than 2m, the depth is no more than 1m (mostly within 0.6m), and the height is generally within 3M. The common angle steel column shelf structure has a light and beautiful appearance, which is mainly suitable for storing light and small items. Less capital investment, widely used in electronics, light industry, culture and education and other industries.Shopping Trolley manufacturer

(2) medium shelf: the load capacity of each layer of unit shelf is generally between 200 ~ 800kg, and the total load is generally no more than 5000kg. The span of unit shelf is usually no more than 2.6m, the depth is no more than 1m, and the height is generally within 3M. If the unit shelf span is more than 2m, generally only beam type and medium shelf type shelves can be selected. Compared with the beam type medium-sized shelf, the layer spacing can be adjusted, leaving more room, more stable and beautiful. Better coordination with the environment, more suitable for some warehouses with high cleanliness requirements; The beam type and medium shelf type shelves are more industrialized, which are more suitable for storing metal structure products. Medium shelf shelf is widely used in all walks of life.
