Pallet live racking is similar to pushback racking; apart from the fact that you load stock in one aisle and remove it from the next. A first in, first out system (FIFO) allows you to operate automatic stock rotation. Each lane is usually dedicated to storing one product variant or for marshalling loads in or out. Pallets are loaded on rollers sloping towards the pick face. When you remove a pallet, gravity and an automatic braking system bring the pallets stacked behind it to the front of the rack at a controlled pace, so your picking face is always full.
