Pushback
Increased Density
Today's challenge in warehousing is to store an ever increasing number of pallets, with an ever increasing number of products in a fixed storage space. These two factors pull in opposite directions. Pushback storage increases the pallet count, while offering many more pick faces than traditional high density storage systems like drive-in.
How It Works
Each pushback lane is equipped with a pair of inclined rails and a series of nested carts (i.e., 4 carts in a 5 deep system). The first pallet is placed by the lift truck on the top cart. He 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. Watch Video
When Does Pushback Apply?
When the average number of pallets per product exceeds five, a pushback system is easily justified. The higher the number, the deeper the lane is feasible (usually 3 lanes per product minimum). These multiple lanes allow rotation to achieve first-in first-out (FIFO). Steadiflo pushback systems can be configured to attain up to 100% more pallets stored than standard pallet racking and equal or greater increases over poorly occupied drive-in or floor storage configurations.

System Flexibility
3D Steadiflo is available in 2,3,4,5 and 6 deep styles and can be arranged as back to back islands or stand alone bays. Number of levels high restricted only by lift truck reach. No special fork trucks are required. Pushback systems are fully operational in freezers, coolers and high temperature environments
Pushback Accessibility
As shown in this 4 deep example below these are 12 pick faces on the pushback system on the left on only 4 pick faces on the drive-in system. the results in higher occupancy and longer honey combing.
