Description

What is Push Back Racking?

Push Back Racking is a heavy-duty racking system specifically for Pallets. Pallets are placed on a sled system that moves on inclined rails. Specially designed to store goods in the depth of the compartment. The highlight of this type of rack is the ability to store many pallets in depth in the same compartment. Push back racking is one of the smart warehouse racking systems. With a unique sliding mechanism, this type of racking helps businesses increase storage density by double compared to standard racking. It becomes an ideal choice for warehouses that need to store large quantities of the same type.

Push Back Racking operates on the LIFO principle, the last pallet imported will be taken out first. This is suitable for goods that are not limited by time.

Operating principle

The system uses stacked sleds or roller systems, placed on rails with a gentle slope towards the aisle.

Loading: Follow the LIFO (first in, last out) rule. When loading the second pallet, the forklift will use force to push the first pallet further inside, then place the second pallet on the remaining sled. This process is repeated until the compartment is full. The last pallet will be placed directly on the rail.

Exporting: When the forklift takes the pallet at the outermost position out of the shelf, the remaining pallets will automatically slide forward thanks to the slope of the rail, filling the gap just created, ready for the next pick-up.

Highlights: The entire import and export process takes place in the same aisle. Right in front of the shelf, so the forklift does not need to go deep inside the shelf structure.

Detailed Structure of Push Back Racking

Pillar: The main load-bearing part of the entire shelf system, usually punched Omega steel, ensuring stability and firmness.

Beam: A connecting bar between the column frames, forming a storage compartment and where the slide rail/roller system is installed.

Guide rail: Fixed to the beam with a slight slope.

Sleds or Rollers: These are the parts that help the pallet move. Sleds are nested together to support and push/slide the pallet.

Pallet Stopper: Prevents the last pallet from sliding out of the aisle.

Protective barrier: Installed at the base of the shelf, helps protect the system from forklift collision.

Advantages of Push Back Racking

Push-back racking is the ideal solution for businesses looking for a balance between storage density and relatively quick accessibility:

Optimize storage density, increase storage capacity up to 50% – 75% compared to Selective shelves. Minimize the number of aisles, convert aisle area into storage space.

Significantly faster than Drive-in racking because the forklift does not have to go deep inside. The entire operation is done from a single aisle.

Each shelf level/storage channel can hold a different SKU code. Fits a wide range of standard forklifts.

Operates efficiently on the LIFO principle. Ideal for items with no or long shelf life.

Practical applications

Push Back Racking system is most suitable for businesses with the following characteristics:

Manufacturing industry: Push Back shelves are placed in factories to store goods, components, etc.

Logistics industry: Short-term storage of goods, can be loaded and unloaded continuously.

Food, beverage, pharmaceutical, medical industries, etc.

Retail industries, in cold storage, freezers, etc.
