What type of shelving Systems suitable for cold storage ?

cold storage is a building that allows fixed spaces to reach a prescribed temperature through artificial refrigeration to facilitate storage of items. Cold storage can be widely used in food factories, dairy factories, pharmaceutical factories, chemical plants, fruit and vegetable warehouses, egg warehouses, hotels, supermarkets, hospitals, blood stations, troops, laboratories, etc. Cold storage is mainly used for constant temperature storage of food, dairy products, meat, aquatic products, poultry, fruits and vegetables, cold drinks, flowers, green plants, tea, medicines, chemical raw materials, electronic instruments.

Common shelf classification:
Through-type rack: This kind of rack has low investment cost and large storage density; it is suitable for storing goods with large batches and few varieties.
Its cargo access mode is to store before taking. Such shelves have the characteristics of high storage efficiency and strong reliability, and they are widely used in mechanical storage operations.

Shuttle-type rack: This kind of rack is similar to drive-in rack, it can be used with shuttle car, its cost is not high. The shelf channel and the working channel of the storage device (shuttle car) are combined into one. The forklift only loads and unloads goods at both ends of the shelf. The shuttle car transports pallet goods from the entrance to the exit. Because the forklift does not need to deposit and withdraw goods in the aisle, this type of rack can meet the first-in first-out requirement, and its safety is high. Compared with drive-in shelves, it has higher operating efficiency.

Push-back shelves: Push-back shelves concentrate the advantages of drive-in shelves and gravity shelves. It is formed by stacking multiple layers of trolleys, and the rails on the shelves have a certain slope, which is suitable for the storage of large quantities of small varieties of goods. This kind of shelf is suitable for places where the requirements for picking goods are not high. The total shelf depth is within 6 pallet depths, the unit cargo weight is within 1500kg, and the shelf height is below 6m. The shelf is manufactured with high precision and follows the first-in last-out working principle, and the forklift does not need to enter the storage channel.

Tray-type shelf: The tray-type shelf is easy to access, simple in design, and easy to install and disassemble. In addition, it has the characteristics of low cost, beautiful appearance, reasonable structure, and strong carrying capacity. The maximum load of this type of shelf can be up to 5 tons. Due to the humanized design, each layer can be adjusted freely. The shelf adopts the plug-in combination type, we do not need welding and screw installation, and the transportation is convenient.

Narrow laneway (VNA) shelves: narrow lane forklifts (also known as three-way forklifts) are used to store and retrieve pallet goods in the laneway to both sides of the shelf. The forks of narrow lane forklifts have three-way rotation and side shift functions, so the forklift does not need to turn at right angles when picking up pallet goods in the aisle. Narrow roadway shelves are widely used in various industries, it can reduce manual labor intensity and errors, improve the level of warehouse automation and management; at the same time, the application of such shelves has the advantages of low storage and transportation losses, small logistics capital backlog, high logistics efficiency, and high storage density.
