Three Main Groups Of Metal Storage Racks

- Oct 14, 2019-

 It is fair to assume that there is no factory, manufacturer or trading firm in the world let alone warehouses and terminals, with no need to store something. All organizations of this kind require storage equipment that could be different in load capacity and specialization and thence in engineering particulars.

In the process of selection of racks for business needs of enterprise it is important to take into account first of all the maximum load capacity of this or that type of rack.

There are three main groups of metal storage racks depending on their design load:

1. Racks for light load (one shelf holds load from 100 to 200 kg)

Hooks or bolts are used for fastening in these racks. The fastening with bolts is more economical option. However, more economical version of rack has certain constraints: the height of one shelf cannot exceed 2.5 m; load on one section is no more than 600 kg. In case when the hooks are used as bracings the height of one shelf increases to 4 m and limit load grows up to 3000 kg. Clear and undeniable advantage of this type of racks is the possibility to move the shelf upward with increment 4.5 m. The shelf can be completely removed when it is required to make room for large-size cargo Substitution of a shelf on racks with bolt fastening will take massively more time and increment with these braces is 2.5 m.

2. Racks for mean load (one shelf holds load from 300 to 400 kg)

This group comprises racks with hook braces as well as racking beam systems with decking. The structures on hooks are capable to withstand loads of 300 kg on one shelf. Their height could reach 4 m. Storage equipment with beams is versatile. Various decking materials could be used on beams, from plywood through metal mesh.

3. Racks for heavy load (one shelf holds load from 800 to 3000 kg)

Racks of two types are represented by this group

•Racks with mesh decking, whereon goods weighing 800-1200 kg could be undoubtedly placed. For another thing there is an auxiliary facility of using a strengthened decking and in so doing we can increase the weight up to 2000 and even 3000 kg. The structure height is 2 to 4 m. These racks with removed decking could be used for storage of pallets (cargo trays). Apart from that a combination of decking and pallets in these racks is also possible. For example the first layer goods are stored on decking and the upper layers are occupied with pallets.

•Shelvings: could withstand less significant load: not more than 800 kg on one layer. The height of these structures is 2 to 4 m.

Racks are also subdivided by engineering and operational particulars. Thus the racks with regard to their limit load and designated area could be:

•Cargo racks with sufficiently high load capacity and convenient for accommodation of single-piece cargoes.

•Archive racks, serving for organization and keeping of paper documents and ensuring speedy and easy access to them.
