Pallet Stacking Systems Pallet stacking systems have pallets stacked on top of each other, hence the name pallet stacking system . There are two types of pallet stacking systems— block stacking , often referred to as floor storage , and stacking frames . Block Stacking Block stacking refers to unit loads stacked on top of each other and stored on the floor in storage lanes (blocks) typically 3 to 10 loads deep. Block stacking is particularly effective when there are multiple pallets per stock-keeping unit (SKU) and when inventory is turned in large increments; that is, several loads of the same SKU are received and/or withdrawn at one time. Because no racking is required, the investment in a block stacking system is low. Block stacking is easy to implement, and it allows near-infinite flexibility for floor-space configuration. Loads in a block are retrieved last in, first out (LIFO). Hence, if highly restrictive (more strict than lot or code date) first in, first out (FIFO) requirements are in place, block stacking is not a feasible storage method (Figures 5.2 through 5.4). Figure 5.2 Block stacking at a Coca-Cola plant warehouse (Charlotte, NC). Note that loads are stacked one high, two high, two and half high by straddling adjacent stacks, and three high depending on the weight of the product.
