Therefore, storage shelves have played a huge role in the development of modern industry. With the development of modern industrial civilization, the structure and functions of storage shelves have been continuously improved.


Classification of storage shelves


1.Heavy pallet rack


The Heavy-Duty Pallet Rack is made of high-quality cold-rolled steel plate by rolling. The column can be as high as 10 meters without joints in the middle. The beam is made of high-quality square steel, which has large bearing capacity and is not easy to deform. Reliable, easy to disassemble and assemble, and use lock nails to prevent the forklift from lifting the beam when the forklift is working; the surfaces of all shelves are treated by pickling, phosphating electrostatic spraying and other processes, anti-corrosion and rust prevention, and beautiful appearance. Suitable for large warehouses.

 

2. Medium-sized shelves


The medium-sized shelves are unique in shape, reasonable in structure, easy to assemble and disassemble, do not need screws, and are sturdy and strong, with large carrying capacity. They are widely used in shopping malls, supermarkets, corporate warehouses and institutions.


3. Light shelf


The Light Punching Rack is a highly versatile structural system, which can be widely used in assembling light material racks, workbenches, tool carts, suspension systems, safety nets and support frames. The length of the punching angle steel can be quickly cut according to the scale, assembled with screws, corrected and reinstalled, so that it can not only meet the needs of carefully planned use, but also meet the needs of emergency use.


 4. Mould rack


Mold racks are also called drawer racks or mold racks, which mainly store various mold items. According to the load capacity requirements, they are divided into light mold racks and heavy mold racks. The top of the shelf can be equipped with a mobile hoist to facilitate the lifting of the mold.

  

5. Beam type shelf


The beam type rack is safe and convenient, suitable for all kinds of warehouses, and direct access to goods. It is the simplest and most widely used shelf, which can make full use of space. The convenient pallet access method is used to effectively cooperate with forklift loading and unloading, which greatly improves the work efficiency.


Mechanical equipment requirements: anti-balance forklift or stacker. The stacker can increase the utilization rate of ground space by 30%, and the operating height is more than 16 meters.


The characteristics of beam type shelves: smooth inventory turnover; can provide 100% selection ability; improve the average pick-up rate; provide high-quality product protection; because beam type shelves are suitable for the storage of goods with many varieties and large batches, for convenient access , There will be more roadways designed, so the ground utilization rate is relatively low.


 6. Corridor type shelves


Corridor type shelves have also become through type shelves, drive-in type shelves. Designed to store a large number of similar pallet goods. The trays are stored one by one on the support rail in the depth direction, which increases the storage density and improves the space utilization. Such shelves are usually used in occasions where storage space is expensive, such as refrigerated warehouses.


Corridor racks have 4 basic components: frame, guide rail support, pallet guide rail and diagonal rod. This kind of shelf warehouse has a high utilization rate, which can realize first-in-first-out or first-in-last-out; suitable for storing large quantities, small variety of goods, and batch operations; the smallest space can provide the largest storage capacity; it is suitable for large quantities and small varieties of goods Store the job. The forklift can directly drive into the cargo lane to access the cargo, which is extremely convenient.


Mechanical equipment requirements: the characteristics of counter-balanced forklifts or stackers. Suitable for storage with low inventory flow; 20%-30% optional; for warehouses with low pick-up rate. Ground utilization rate: 60%, which is relatively high (calculated based on the above design).


7. Gravity shelf


Compared with ordinary pallet racks, gravity racks do not require operating channels, so it increases space utilization by 60%; pallet operations follow the principle of first in, first out; automatic storage and rotation; the separation of storage and picking actions greatly increases output, because The self-gravity makes the goods slide, and there is no operating channel, so the number of transportation routes and forklifts is reduced. On the aisles of each layer of the shelf, a certain sloped guide rail with a track is installed, and the unit cargo in the warehouse flows from the inbound end to the outbound end under the action of gravity.


In such a warehouse, there is no working channel between the rows, which greatly improves the utilization rate of the warehouse area. However, when using it, it is best that the goods on the same row and on the same floor should be the same goods or goods that are in and out of the warehouse at the same time. The layer height is adjustable, equipped with various types of forklifts or stackers, which can realize quick access to various pallets, and the maximum load capacity of the unit cell can reach 5000kg. It is the most commonly used storage method in various industries.


8. Cantilever rack


Cantilever racks are suitable for storing long materials and irregular goods. The extended cantilever has light structure and good load capacity, and can greatly improve the utilization rate and work efficiency of the warehouse when storing irregular or special length materials. effectiveness. After the shelf is added, it is especially suitable for warehouses with small space and low height. It is easy to manage and has a wide field of vision. Compared with ordinary shelf racks, the utilization rate is higher.


9. Attic shelf


The loft-style shelf is a fully assembled structure. It can be made of wood, checkered board, steel plate, and other materials as floor slabs, and can be flexibly designed into two or more layers, suitable for hardware tools. Electronic equipment, mechanical spare parts and other items are stored in small packages, with a wide variety of storage and a small amount of goods to make full use of space. It is suitable for limited venues with many varieties and small quantities. It can increase the utilization rate several times on the existing venues and can be operated with elevators. Fully assembled structure, special light steel floor, low cost and fast construction. According to the actual site and needs, it can be flexibly designed into two floors or multiple floors to make full use of the space.


 10. Fluent shelf


Using fluent strips, put the goods into plastic boxes or turnover boxes, and use the weight of the goods to realize the first-in first-out of the goods. It is suitable for the storage of materials on the production line or assembly line. The material box can slide down the rollers by gravity.


 11. Shuttle rack


Forklifts do not need to enter the tunnel, which saves time and improves the safety of personnel and goods. The efficiency of cargo storage in the warehouse is greatly improved, and the warehouse space is fully utilized. The warehouse can use about 80% to 85 of the space; suitable for different types of products can be divided Flexible access to floors; compared to the drive-in rack and the through rack, the structure is very stable and the safety factor is high. It can realize first-in first-out and first-in-last-out.


12. Special shelves


Special racks include six categories: mold racks, oil barrel racks, fluent racks, net racks, climbing carts, and net compartments.


With the development and expansion of the scale of enterprises, the quantity of logistics shelves has increased significantly. With the increasing shortage of land resources, the pressure of rising warehouse shelf rents, and the increasing labor cost, more and more enterprises are improving the functions of warehouse shelf systems and increasing warehouse shelves. Space utilization is an indispensable part of modern enterprise warehouse racks and logistics rack centers. Accelerating logistics speed has highlighted higher requirements, and usage has increased rapidly. Driven by demand, the shelf industry has achieved rapid development. However, due to the lack of industry standards for storage shelves, the warehouse-type shelf industry is facing increasingly fierce market competition.
