Drive in pallet racking is a high-density storage system used in warehouses to store pallets on a first in/last out (FILO) basis. Pallets are loaded and retrieved from the front side of the rack and forklift trucks drive directly into the rack's bays to get to the stored product. The last pallet loaded becomes the first pallet accessible, creating a denser and more uniform load in a confined storage area. When compared to conventional selective rack systems, the same amount of storage can be achieved in a much tighter area with high-density drive in or drive racking system.
The drive in racking system is a kind of continuous whole rack system which is not divided by channels. On the support rails, the pallets are stored according to the depth direction, one after the other, which makes the high-density storage possible. Drive in pallet racking is suitable for the storage of goods with small variety and large quantity. It is often used to store and enlarge batches of the same type of goods. It has high space utilization and is suitable for occasions with high storage space costs such as the food industry, the chemical industry, the clothing industry, and cold storage. Its storage cost per site is relatively low.
The drive in pallet racking system can be divided into one-way and two-way arrangement according to the picking direction. The total depth of one-way (wall area) rack should be controlled within the depth of six pallets, and the total depth of two-way (middle area can be picked up on both sides) rack should be controlled within the depth of 12 pallets, so as to improve the efficiency and reliability of forklift access (in this kind of rack system, the forklift is a continuous "high lift and high hit" operation mode The forklift is easy to shake and hit the shelf, so it is very important to consider the stability fully). The stability of this kind of storage system is weak, so the rack should not be too high. Generally, it should be controlled within 10 meters. In order to strengthen the stability of the whole rack system, in addition to the larger specification and model selection, the drive through pallet racking is also necessary to add a fastening device. Single cargo should not be too large or too heavy, usually, the weight should be controlled within 1500kg, and the tray span should not be more than 1.5m. The forklift is usually a forward-moving battery forklift or a counterweight battery forklift.
Because of the intensive storage of goods and the high requirement of stability, the drive in pallet racking needs more rack accessories. Through the connection of accessories and rack column pieces, the goods can be safely and intensively stored on the bracket beam, making the best use of space. The accessories of drive through racking system include: sidebars/bracket (the main connection between bracket beam and rack column, divided into the single side and double side), bracket beam (the main supporting rack layer for goods storage), top beam (the connection and stability of rack column), top pull (the connection and stability of rack column), back pull (the connection and stability of rack column, used for the unidirectional arrangement of the shelf), foot guard (the front protection of shelf), rail guard (fork) When the vehicle enters the roadway, the rack protection parts, etc.
Better use of drive in racking system requires attention that when designing a new warehouse or transforming an existing warehouse, it is necessary to review and study the system characteristics applied in the warehouse. Because of the drive in pallet racking system can achieve the maximum storage capacity in the smallest space, so this kind of economic logistics scheme can be selected to maximize economic efficiency.
