Drive-in racks can be used for forklifts (or unmanned trucks with forks) to drive into the channel to access the goods, which is suitable for the storage of goods with small varieties and large batches. Except for the cargo space close to the aisle, because the forklift needs to enter the shelf to store and retrieve the goods, it is generally recommended that the single-sided pickup does not exceed 7 cargo space depths. In order to increase the operating speed of forklifts, guide rails can be selected according to actual needs. Compared with beam racks, the storage space utilization rate of drive-in racks can be increased by more than 30%. It is widely used in wholesale, cold storage, food and tobacco industries.
