Storage racks are widely classified, which can be classified according to their scope of use, load-bearing capacity, storage and retrieval methods, and storage goods. The reason for such a wide classification is that it can provide convenience and efficiency for various industries. So what is the difference between narrow aisle racks and heavy-duty storage racks?
Heavy duty rack is the most common form of rack among various storage racking systems. The fully assembled structure of columns and beams is simple and effective. Heavy-duty storage racks are the most commonly used type of racks, with each layer bearing more than 500 kg, hence the name. It has good picking efficiency and can store heavier items, but the storage density is low. Heavy-duty storage racks, also known as pallet racks, have the characteristics of large load-bearing capacity, wide height adaptation range, mechanical access, and high selection efficiency, but the space utilization rate is average. The pallet rack is widely used in manufacturing, third-party logistics, distribution centers, and other fields. It is not only suitable for multi-variety and small-batch items but also suitable for small-variety and large-batch items. This type of storage rack is most commonly used in high-level warehouses and super high-level warehouses (most racks in automated three-dimensional warehouses use this type of storage rack).
Narrow aisle racks are a type of storage rack, named narrow aisle or narrow aisle racks due to their relatively narrow forklift handling channels. The main body of the warehouse storage rack system is a crossbeam pallet rack system, with the difference being that a “three-way stacking forklift” action guide rail is installed on the ground at the bottom of the rack. The guide rail is usually made of unequal-angle steel, and material-handling forklifts are limited to specialized “three-way stacking forklifts”. The three-way stacking forklifts slide along the established guide rail.
The width of the stacking channel in the rack system is slightly larger than the width of the pallet cargo, enabling high-density storage requirements. At the same time, it inherits all the advantages of the crossbeam pallet rack system. All materials stored in the storage racking system have 100% selectivity, and forklifts can store any pallet of goods at any time. Fast storage efficiency and very high storage density bring significant production efficiency and cost efficiency to storage and logistics centers that are suitable for using narrow aisle rack systems.
