What defines a push-back rack?

1. A system where items are only retrieved from the front

2. A high-density system that uses inclined rails

3. A type of storage that requires external support

4. A low-density storage solution

The correct answer is: A high-density system that uses inclined rails

A push-back rack is defined as a high-density storage system that utilizes inclined rails to facilitate the movement of pallets. This design allows pallets to be loaded from the front of the rack, where they slide backward to the rear of the storage lane. When pallets are retrieved, the remaining pallets automatically push forward due to gravity on the inclined rails. This mechanism maximizes storage space by allowing for deeper storage while maintaining quick access to items. The high-density nature of push-back racks is a key feature, as it enables warehouses to store a large number of pallets in a compact area, optimizing storage capacity. Additionally, the design supports first-in, last-out (FILO) inventory rotation, which can be advantageous in various operational settings.
