For Part 1 of this blog, we covered the different components of pallet rack and how to determine which type you need for your operation. Part 2 is going to cover the different types of pallet rack systems!

Types of Pallet Rack:


  • Most common pallet rack used
  • Efficient when you have a low quantity of SKUs
  • Easy accessibility
  • Least dense

Double Deep

  • Fewer forklift aisles
  • Less selectivity
  • More storage density than selective rack

Drive In

  • Load and retrieve from the same side, creating LIFO inventory retrieval
  • Efficient when you have large quantities of different SKUs
  • Low selectivity
  • Cost effective
  • High density
  • Requires fewer forklift aisles

Push Back

  • Similar to drive in
  • Allows you to store pallets 2-5 deep and still have easy access to different SKUs
  • This system uses steel carts on inclined rails, and uses gravity flow to move product towards the pick aisles
  • Cost effective
  • High density
  • LIFO

Drive Thru

  • Pallet racking system that loads from one side and unloads from the other to create FIFO inventory retrieval.
  • Forklifts can enter from both aisles on either side of the rack
  • Low selectivity
  • High density
  • Excellent option for freezers

Pallet Flow

  • Similar to drive thru
  • This system uses wheels or rollers on sloped beam levels, and uses gravity flow to move product towards the pick aisle
  • It is perfect for fast-moving product with FIFO inventory retrieval
  • High-density

Carton Flow

  • Uses a gravity feed rear load design
  • Merchandise is loaded in the rear of each runway, and as an item is removed from the front, the item behind it slides forward on inclined rails in place of the previous item
  • FIFO


  • Elongated storage, furniture rack, tube rack, lumber rack
  • Single sided or double sided
  • Various heights and widths between uprights and lengths of the arms
  • High selectivity
  • Can use decking to span arms to create a solid level

As a company, Storage Solutions has been committed to providing our customers with the best in new and used material handling equipment since it all started way back in 1978.  One of the things that enables us to do this is the relationships we have with our partners, including 3D Storage Systems.

Storage Solutions has been proud to partner with 3D Storage Systems for the past several years.  They have grown to become one of the largest producers of dynamic storage systems in North America. 3D offers a wide range push-back products

Our team was fortunate to have a 3D representative come to our facility and teach us some important information about their products.  We thought the information was so beneficial that we wanted to share a few key items with our readers!

Here’s what you need to know…


What is push-back?

Push-back storage increases pallet count, while offering many more pick faces than traditional high density storage systems. Each push-back lane is equipped with a pair of inclined rails and a series of carts. The first pallet is placed by the lift truck on the top cart. The lift truck driver then loads the second pallet by pushing back the first load and placing it on the next exposed cart. Pallets three and four are loaded similarly. The last pallet is placed on the rails themselves. When removing product, the lift truck takes out the front pallet allowing the pallets on carts behind it to roll gently to the front of the rack.


What’s the difference between a push-back system and a standard pallet rack system?

A push-back system offers less selectivity than a standard pallet rack system, however, it is a denser storage method that utilizes warehouse space more efficiently because it requires less forklift aisles.

How does the cost of push-back compare to standard pallet rack?

Push-back is a greater investment than standard pallet rack because more components are involved, therefore more material, but the square-footage cost per pallet actually decreases because more pallets can be stored in the space.

We thoroughly enjoyed expanding our knowledge on the push-back system with 3D Storage Systems, and hope this information will be useful to our readers.  If you have any additional questions, our online sales team is standing by! Give them a call at 866.474.2001!

TOTW Pushbackpush back pallet rack system allows palletized goods and materials to be stored by being pushed up a gently graded ramp. Stored materials are allowed to flow down the ramp to the aisle.

This rack configuration allows for deep storage at each rack level and last-in, first-out storage. All of the loads are stored and retrieved from the aisle. When a new load is deposited into a lane, it pushes back the one already at the front and all those behind it. Then, when that load is picked, the contents of the lane all move forward again, hence the term “push back rack.”

Why use a push back pallet rack system?

  • The nested carts make placement and retrieval easy
  • It saves storage space which leads to less cost
  • They offer the same storage density as and drive-in/drive-through racks

If you are looking to utilize space in your warehouse make sure to get some information on the push back pallet rack system. Storage Solutions would love to help you create the perfect warehouse for your company.
