Push-Back Racking System

Push Back Racking operates using a gravity-fed mechanism, where pallets are loaded from the front and pushed back into the racking lanes. It follows the Last-In, First-Out (LIFO) inventory method, making it suitable for products with longer shelf lives or those not requiring frequent rotation.
In contrast, Pallet Flow Racking employs gravity rollers and a sloped system to push pallets forward, ensuring the First-In, First-Out (FIFO) inventory method, ideal for perishable goods or products requiring strict date tracking. Push Back systems offer higher density storage by reducing the need for aisles, while Pallet Flow systems provide faster access for time-sensitive products.

While traditional Push Back Racking systems are optimized for single-SKU lanes to ensure smooth and predictable pallet flow, advanced configurations can support mixed SKUs within the same lane. This requires more precise control mechanisms, such as adjustable rollers or dedicated stops, to prevent pallets from becoming misaligned. This approach allows for more flexible storage while maintaining efficient space utilization, though it may reduce the overall system’s efficiency compared to single-SKU lanes.

Technically, Push Back Racking systems incorporate several safety features to minimize risk:

• Automatic pallet stop systems to prevent pallets from overhanging or falling during loading/unloading.
• Brake mechanisms within the rails or carts to control the speed at which pallets move, preventing excessive momentum that could cause accidents.
• Rack impact protection using heavy-duty bumpers or reinforced posts to protect the racking structure from forklift damage.

Regular safety audits are essential, ensuring proper alignment and load distribution within each lane.

Maintenance for Push Back Racking involves periodic inspection of the following:

• Carts and rollers: Regular checks for wear or damage to ensure smooth pallet movement. Clogged or damaged rollers can cause jams or slowdowns, leading to operational inefficiencies.
• Inclined rails: Ensure that the rails are free from debris and properly lubricated to maintain smooth operation.
• Structural integrity: The racking framework should be checked for structural weaknesses, particularly in high-stress areas like the load-bearing supports.
• Pallet adjustments: Check that pallet sizes match the racking configuration. Mismatched pallets can cause alignment issues and reduce overall system efficiency.

Scheduled maintenance and cleaning of these components help extend the system’s lifespan and improve operational efficiency.

The cost of Push Back Racking depends on several factors, including the size of the system, the number of levels and lanes, weight capacity, and any additional customizations. On average, Push Back Racking systems can cost start from RM400 per pallet position in Malaysia. Installation, material quality, and specific requirements (e.g., for cold storage) may further impact the price.

Push Back Racking systems typically have the following specifications:

1. Material: High-strength steel for durability and load support.
2. Configuration: Can accommodate pallet depths of 2 to 6 deep per lane.
3. Weight capacity: Each pallet level can support 500kg to 2,000kg, depending on the design.
4. Rails: Inclined rails and carts enable the pallets to roll smoothly in and out.
5. Design flexibility: Can be customized for warehouse height and width requirements.

No, Push Back Racking Systems do not require special forklifts. Standard forklifts, including counterbalance and reach trucks, are compatible. Operators can easily load and retrieve pallets without modifying existing equipment.

Push Back Racking Systems can be configured to store pallets from 2 to 6 deep per lane, depending on the design and operational needs. This depth provides flexibility for maximizing storage density while ensuring efficient inventory management. Larger depths may require considerations for pallet stability and load weight.

Yes, Push Back Racking Systems are ideal for use in cold storage and freezer environments. They are made from materials and finishes, such as galvanized or powder-coated steel, that can withstand low temperatures and resist corrosion. This makes them suitable for storing perishable goods efficiently in temperature-controlled warehouses.
