Brief Introduction of push back storage rack
1. Push back storage rack has enjoyed rapid growth in popularity recently due to offering
similar space savings as drive-in, with typically 3 to 5 times
greater selectivity. This growth has been spurred by marketing
trends such as rapid increases in number of SKUs, mass
customization, and more rapid product obsolescence.
2. Each level in a push-back system holds a series of nested
rolling carts, operating in a lane which slopes upward away from
the pick face.
3. To load the lane, the first pallet loaded in the lane is loaded
onto the top cart. To load the next pallet in the lane, the lift
truck operator lines up in front of the first pallet and pushes
against it, causing the first pallet to roll back away from the
pick face, and exposing the next cart, which the second pallet can
be lowered onto, once it’s in position. The process is repeated
until the lane is full. To empty the lane, the operator slowly
removes the last pallet in, and the others roll back forward, down
to the pick face. Similarly, the process continues until the lane
Benefits of push back storage rack:
1. High densities – three and four deep systems are common, which
allows blocks of 6 or 8 deep, with back to back rows. Depths of up
to 6 deep are also available, at higher costs.
2. Improved selectivity over Drive-In, which Push-Back often
3. Efficiency vs. Drive-In – trucks do not need to drive into rack
loads come to them at the pick face.
4. Less rack. Truck and product damage vs. Drive-In- with no trucks
driving inside rack.
