Each lane of pushback comprises of carts that roll on a slope. Each pallet is pushed to the back when being stored. When the front pallet is picked, the pallets roll forward to ensure only the front pick face is accessed by forklifts.
BENEFITS
Reduced aisles to improve density in your warehouse space
Improved selectivity vs drive-in racking. Safer as well.
Be aware of your height restriction in the facility. Because this system includes a slight slope, the furthest pallets deep will have a high top stored height.
