Which Racking Systems Are Suitable For Cold Storage?

Cold storage is the abbreviation of low-temperature cold storage, which is mainly used to store meat, dairy products, aquatic products, medicines and other items that need to be stored at low temperature. The temperature of the cold storage is generally between minus 5 degrees and minus 30 degrees. Because the temperature is relatively low, the requirements for shelves are relatively high, so which storage shelves are suitable for cold storage?

1. Drive-in Rack:

The investment cost of the drive-in rack is relatively low, and it is a continuous integral shelf that is not divided by aisles. The drive-in rack adopts the pallet access mode. On the support rails, the pallets are stored in the depth direction, one after the other. The cargo access mode is to store first and then take out. It is suitable for the storage of large quantities of goods with large horizontal dimensions, large quantities, and a single variety. It is a shelf with high storage efficiency among storage shelves, and is suitable for most handling machinery storage operations.

2. Radio Shuttle Rack:

The radio shuttle rack is used together with shelves, trolleys and forklifts. The shuttle rack is a high-density storage rack with high work efficiency and greatly reduces the waiting time for operations. The access method of goods can be first in, first out, or First in, last out, high safety factor, reducing the collision between shelves and forklifts, and improving safety and productivity. Compared with other types of shelves, the overall investment is less.

3. Pallet rack:

The span (length) of the pallet rack is mainly determined by the size of the pallet. Generally, two conventional pallets can be placed on one shelf. Pallet racks do not need laminates, just install cross beams on the beams, which can save more costs, pallet racks have large spans, high load capacity (up to 5 tons), stable structure, high utilization rate, and flexible access convenient.

4. Push Back Rack:

Push back racks are evolved from pallet racks. The front and rear beams are overlapped and connected by multi-layer trolleys. The stacked goods are placed on the trolleys and pushed in from the outside, and the goods stored later will push the original goods inside. When storing and transporting goods, the forklift is only located at the lower end of the shelf aisle, and does not need to enter the shelf goods storage aisle. It has the characteristics of high storage density and fast storage and transportation speed. The total depth of the shelf is within 5 pallets, and the unit cargo weight is 1500kg. Within the height of the shelf is below 6m, the manufacturing precision of the shelf is high, and it follows the working principle of first-in, last-out.

5. VNA Rack:

VNA rack is called narrow-aisle racking because the forklift handling channel of the racking system is relatively narrow. VNA racks use three-way stacking forklifts to store and retrieve palletized goods from the narrow-aisle racks on both sides of the aisle. The three-way stacking forklift has three-way rotation and side shifting functions, so the forklift does not need to turn at a right angle when picking up and storing palletized goods in the channel. Narrow-aisle racks store a large amount of goods, and the goods come in and out more frequently. At the same time, there are high requirements for picking goods. Narrow-aisle racks are used in various industries, which can reduce labor intensity, reduce errors, reduce storage and transportation losses, and reduce The backlog of logistics funds, improve the level of warehousing automation and management, improve logistics efficiency, high storage density and other advantages.
