Let’s dive in!
What Is Push-Back Pallet Racking?
Push-back racking is a high-density storage system, allowing up to six pallets deep storage on either side of an aisle.
Push-back racking works with at least three nested mobile carts, gliding on sloped rails to hold and carry pallets. The first pallet, loaded from the front, sits on the top cart. When the second pallet is loaded onto the cart, it pushes the top cart with the first pallet back.
It operates like a soft drink cooler in a convenience store, where when you pull a bottle out, a new one slides forward.
The pallet ‘push-back’ mechanism makes pushback racking ideal for operations using the Last-In, First-Out (LIFO) inventory method.
Push-back racking can achieve higher density storage – up to 75% more than selective racking – while allowing more selectivity with storage. But you can only store the same SKU in a single lane.
Pros
Higher storage density than selective racking
Requires fewer aisles
Easy product accessibility and selectivity, reducing picking time
No specialty equipment is necessary
Multiple deep locations offer more access points
Cons
More expensive storage system than selective or drive-in racking
Higher chance of lost pallet positions due to the size of mobile carts
Inventory can’t overhang the front or back of the pallet
Not ideal for FIFO inventory
Requires good quality, consistently-sized pallets
Cost
Push-back racking is a more expensive storage system than selective or drive-In. Budget $151 to $295 per pallet position, depending on the number of positions (e.g. 2, 3, 4, 5, or 6).
Applications
General warehousing and retail
Operations using either First-In, First-Out (FIFO) or Last-In, First-Out (LIFO)
Storage with more pallets per SKU that requires greater storage density
When order picking is not required from pallets
Pallet flow racking – or “gravity flow” racking – is another high-density racking system where pallets are placed in the system’s rear end on a series of rollers with a centrifugal braking system.
It’s an ideal system for FIFO inventory because pallets are loaded on one end and unloaded at the other end of the system.
In a pallet flow racking, when you load a pellet from the aisle, the pallets roll forward by gravity to the front of the system. Similarly, when a pallet is removed from the front, the pallets behind roll to the front of the lane.
Generally, pallet flow racking supports very high-density storage, holding up to 20 pallets deep in one lane. This minimizes the aisles needed to store items while maintaining efficient inventory turnover.
Pros
Superior product/storage density
Increased product selectivity
Good for high product turnover
Fewer aisles are needed, so more space can be utilized
Cons
The most expensive racking type
Requires high-quality pallets
Requires more maintenance
Operates a limited number of SKUs in large volumes
Cost
It's the most expensive of all pallet racking types, with costs ranging from $300 to $500 per pallet position.
Applications
This storage type is used for pallet loads in an order-picking application, such as:
Freezer warehouses
Food distribution centers
Grocery
A cantilever racking system stores long, heavy, or bulky items that cannot be easily stored on pallets, such as lumber, steel pipes, wood, and textiles.
Cantilever racking consists of multiple adjustable protruding arms to store items horizontally, unlike pallet racks with vertical uprights, which limit the length of stored items.
They’re available in double and single-sided units, allowing item storage on one side or both. With no front columns, cantilever racks are easier to access, load, unload, and add space.
Pros
Easier to access, load, and unload due to fewer structural components
Easier to install
Easier to add space or adjust to accommodate changing inventory
Cons
Takes more space
Requires wider aisles
May require a specialized lift truck, like a Combilift
Only stores specialized items like lumber, steel pipes, wood, textiles, etc.
Cost
Cantilever racking with a single-sided design can cost between $850 and $1,700 per bay.
Applications
Building and construction supplies
Metal supply and retail shops
Plumbing suppliers
Wood and furniture
