Drive-in racking is a storage system designed to maximize space in warehouses by allowing pallets to be stored in a compact manner. This system uses a series of rails that enable forklifts to drive directly into the racking structure, placing pallets deep within the racks. It is particularly useful for high-density storage of similar products. The main advantage of drive-in racking is its ability to increase storage capacity while minimizing aisle space. This system operates on a first-in, last-out (FILO) basis, making it ideal for products with a longer shelf life or those that do not require frequent access.
