What are the classification and advantages and disadvantages of storage shelves

There are many types of storage shelves. According to the carrying capacity of the shelves, the shelves are divided into light shelves, medium shelves, and heavy shelves; according to the height of the shelves, the shelves can be divided into low shelves, middle shelves, and high shelves; according to the form of shelves, Shelves can be divided into channel shelves, intensive shelves, and rotating shelves.
Various shelves have their own advantages and disadvantages: Lightweight shelves: Lightweight perforated shelves are a highly versatile structural system, which can be widely used in assembling lightweight material racks, workbenches, tool carts, suspension systems, and safety guards. Net and supporting skeleton. 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 carefully planned use, but also meet the needs of emergency use.
Medium-sized shelves: The medium-sized shelves are unique in shape, reasonable in structure, easy to assemble and disassemble, do not require screws, and are sturdy and strong, with large carrying capacity. They are widely used in shopping malls, supermarkets, corporate warehouses and institutions.
Heavy-duty pallet racking: It is made of high-quality cold-rolled steel plate and formed by rolling. 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. Reliable connection, easy disassembly and assembly, and the use of 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.
Through-type shelves: also known as corridor-type shelves, drive-in shelves. Designed to store a large number of similar pallet goods. The trays are stored on the support rails one by one in the depth direction, which increases the storage density and improves the space utilization rate. 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, and can realize first-in first-out or first-in-last-out. It is suitable for storing large quantities of goods with few varieties and batch operations. The smallest space available provides the largest amount of storage. It is suitable for large-volume, small-variety cargo storage operations. The forklift can directly drive into the cargo lane to access the cargo, which is extremely convenient for operation. Mechanical equipment requirements: counter-balanced forklift or stacker racks. Features: suitable for storage with low inventory flow; 20%-30% optional; used for warehouses with low pick-up rates. Ground utilization rate: 60%, which is relatively high (need to be calculated based on the above design).
Beam type shelf: It is the most popular and most economical type of shelf, safe and convenient, suitable for various warehouses, direct access to goods. It is the simplest and most widely used shelf. Can make full use of space. It adopts convenient pallet access method, effectively cooperates with forklift loading and unloading, and greatly improves the efficiency of working beam type racking. Mechanical equipment requirements: counterbalanced forklift or stacker. The stacker can increase the utilization rate of the ground space by 30%, and the operating height is more than 16 meters; the characteristic of the beam type shelf: smooth inventory turnover. Can provide 100% selection ability. Improve the average pickup rate. Provide high-quality product protection. Because the beam type rack is suitable for the storage of goods with many varieties and large batches, in order to facilitate the access, there will be more roadways designed, so the ground utilization rate is relatively low.
Attic shelf: Fully combined structure, can use wood plate, checkered board, steel plate, and other materials as floor slab, 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 the 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 the space.
Mold rack: also called drawer rack or mold rack, it mainly stores various mold items, and is divided into light mold rack and heavy mold rack according to the requirements of layer load capacity. The top of the shelf can be equipped with a mobile hoist cart to facilitate the lifting of the mold.
