Pallet flow shelving, also known as carton flow rack or gravity flow rack, is a storage system designed for high-density and efficient order picking of cartons or cases. It utilizes inclined flow lanes and gravity to move products from the loading end to the picking or unloading end. Here's some information about pallet flow shelving:

1. Design and Components:

- Flow Rails or Rollers: Pallet flow shelving consists of inclined flow rails or rollers that are placed on multiple levels within the shelving system. These flow lanes create a sloped surface that allows cartons or cases to slide or roll under the force of gravity.

- Entry and Exit Points: Pallet flow shelving typically has separate entry and exit points, allowing for the loading of cartons at one end and the retrieval of cartons at the opposite end.

- Speed Controllers: Speed controllers or brakes are often incorporated into the flow rails or rollers to regulate the speed of carton movement and ensure controlled flow.

- Dividers or Lane Guides: Dividers or lane guides are used to separate flow lanes and keep each lane dedicated to specific products or SKUs.

2. Operation and Advantages:

- Efficient Order Picking: Pallet flow shelving enables a first-in, first-out (FIFO) inventory rotation, ensuring efficient order picking and minimizing product spoilage or expiration.

- High Density Storage: Pallet flow shelving maximizes storage density by utilizing both depth and height. It allows multiple cartons to be stored on each flow lane, and the shelving can be stacked vertically.

- Space Optimization: Pallet flow shelving requires fewer aisles compared to traditional selective shelving systems, optimizing the use of warehouse space.

- Improved Order Accuracy: By utilizing gravity to move products to the picking end, pallet flow shelving facilitates easier access and retrieval of the correct products, reducing picking errors.

- Ergonomic and Safety Benefits: Pallet flow shelving reduces the need for workers to reach or bend, as the products come to them at the picking end. This can improve ergonomics and reduce the risk of injuries.

3. Considerations:

- Carton Compatibility: Pallet flow shelving is suitable for cartons or cases that can smoothly slide or roll on the flow rails or rollers. The compatibility of the cartons with the flow lanes should be considered during system design.

- Flow Speed and Control: The speed of carton flow can be adjusted by incorporating speed controllers or brakes to match the operational requirements and ensure safe and controlled flow.

- Maintenance: Regular maintenance is necessary to ensure the smooth operation of the flow rails or rollers, including cleaning, lubrication, and inspection for any wear or damage.

Pricing for pallet flow shelving can vary based on factors such as the size of the shelving system, the number of flow lanes, the load capacity, the specific supplier or manufacturer, and any additional features or accessories. It is recommended to consult with shelving suppliers or material handling equipment providers to obtain accurate pricing based on your specific needs and project details. They can provide detailed quotations, assist in designing the most suitable pallet flow shelving system for your warehouse, and offer guidance on installation and maintenance.
