Racking Systems: Pallet Racking: Push Back

P-90 Push Back Racking is a form of pallet flow rack in which pallets are stored two, three or four deep with a telescopic trolley system. Using a fork lift truck, pallets are both loaded and unloaded from the same aisle. The palletised load is deposited on the top trolley. When the next pallet is inserted this loaded trolley is pushed back into the storage lane. This process is repeated for up to four pallets deep. When a pallet is with drawn from a lane, the remaining pallets stored behind are automatically fed forward under the force of gravity.
