Classification of Warehouse Storage Shelves
1. Heavy Pallet Rack
The heavy-duty pallet rack is made of high-quality cold-rolled steel plate by roll forming. The column can be as high as 10 meters without a joint in the middle. The beam is made of high-quality square steel, which has a large bearing capacity and is not easy to deform. The pendant between the beam and the column is inserted and connected 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, no screws, strong and strong, with large carrying capacity, which 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 punched angle steel can be quickly cut according to the scale, assembled, corrected and reinstalled at will with screws, so that it can not only meet the needs of careful planning, but also meet the needs of emergency use.
4. Mold Rack
Mold racks are also called drawer racks or mold racks, which mainly store various mold items, and are divided into light mold racks and heavy mold racks according to the requirements of layer load capacity. The top of the shelf can be equipped with a mobile hoist to facilitate the lifting of the mold.
5. Beam Type Shelves
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 coordinate with forklift loading and unloading, which greatly improves work efficiency.
Mechanical equipment requirements: counterbalanced 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 quantities, for convenient access , There will be more roadways designed, so the ground utilization rate is relatively low.
6. Corridor Type Shelves/Drive In Rack
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. This kind of shelf is usually used in occasions with expensive storage space, such as refrigerated warehouses.
Corridor type shelves 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-volume, small-variety goods and batch operations; the smallest space can provide the largest storage capacity; it is suitable for large-volume, small-variety goods Store the job. Forklifts can directly drive into the cargo lane to deposit and withdraw goods, and the operation is extremely convenient.
Mechanical equipment requirements: the characteristics of counterbalanced 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 Rack
Compared with ordinary pallet racks, gravity racks do not require operating channels, so they increase the 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 It is the gravity that 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 platoons, which greatly improves the utilization rate of the warehouse area. However, when it is used, 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. The maximum load capacity of the unit cell can reach 5000kg, which 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 forward cantilever has a light structure and good load capacity. It can greatly increase 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 view. Compared with ordinary shelf-type shelves, the utilization rate is higher.
9. Mezzanine Rack/Attic Floor
The loft-style shelf is a fully-combined structure, which can be made of wood plates, checkered plates, steel plates, 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 small batches 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 slab, 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 space.
10. Carton Flow Rack
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 Racks
Forklifts do not need to enter the tunnel, which saves time and improves the safety of personnel and goods. The efficiency of cargo access in the warehouse is greatly improved. 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 layers; compared to the drive-in rack and the through rack, the structure has a solid root and high safety factor, which 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, rising pressure on warehouse shelf rents, and rising labor costs, 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. In order to develop better, the storage shelf industry must continue to develop, Work hard on rack innovation and other aspects.
