Press in shelving is a high-density equipment that stores goods layer by layer in the cargo aisle using forklifts. It is mainly used in the following scenarios: Small and medium batch multi category storage: suitable for goods with multiple categories but moderate single batch quantities (such as electronic accessories, automotive parts), can achieve multi SKU management in limited channels. First in, last out (LIFO) demand scenario: Goods enter and exit from the same end, with new goods pressing in front of old goods, adapting to goods that do not strictly require batch order (such as building materials, packaging materials), and reducing channel occupation. Space utilization priority scenario: The depth of the cargo aisle can be customized (usually 3-5 pallets deep), the number of aisles is small, and the storage density is increased by more than 40% compared to ordinary shelves. It is suitable for scenarios where warehouse space is tight but storage capacity and access flexibility need to be balanced. Optimization of forklift operation efficiency: Forklifts do not need to enter deep into the cargo aisle, only operate at the cargo aisle, reducing the difficulty of operation and adapting to the mechanized storage needs of small and medium-sized warehouses.
