Carton flow rack, also known as gravity flow rack or dynamic flow rack, is a storage system designed to optimize the flow of cartons, boxes, or totes in a warehouse or distribution center. It is particularly suitable for storing and picking fast-moving items with a high turnover rate.

Here are the key features and components of a carton flow rack system:

1. Gravity Flow Design: Carton flow racks are designed with inclined roller tracks or wheel beds that allow cartons or totes to flow smoothly by gravity from the loading end to the unloading end.

2. Lane Dividers: The rack system typically includes lane dividers or separators to create individual lanes for each SKU (Stock Keeping Unit) or product type. This organization helps in maintaining inventory segregation and facilitates efficient picking.

3. Flow Controllers: Flow controllers, such as speed controllers or brake mechanisms, are installed at the pick face to regulate the speed of carton flow and prevent cartons from free-flowing too quickly.

4. Loading End and Unloading End: The loading end is where items are loaded onto the rack, usually done manually or using conveyor systems. The unloading end is where items are picked from the rack for order fulfillment or distribution.

5. First-In, First-Out (FIFO) System: Carton flow racks typically operate on a first-in, first-out (FIFO) basis. This means that the oldest items are picked first, ensuring inventory rotation and minimizing product expiration.

6. Ideal for Order Picking: Carton flow racks are well-suited for order picking operations, especially in industries such as retail, e-commerce, and distribution, where fast and accurate picking of multiple SKUs is essential.

7. Increased Efficiency: The gravity flow design of carton flow racks minimizes the need for manual handling and reduces travel time for pickers, leading to increased efficiency and productivity in warehouse operations.

Overall, carton flow racks are an efficient storage solution for warehouses dealing with fast-moving consumer goods (FMCG), perishable items, or products requiring frequent picking and replenishment. They help streamline order fulfillment processes and improve inventory management, contributing to overall operational efficiency.
