There are many different types of Pallet Racking Configurations that can be used in warehouses depending on their storage needs. They vary from low density like selective rack to high density like pushback, drive in and pallet flow systems. Each of these racking system types has advantages and disadvantages. Some of the Pallet Rack Configurations are described below.

Selective Pallet Rack: This is the most common type of pallet rack system. Cost of installation of this rack system is low in comparison of other configurations. This rack system is readily available and provides access to every pallet of the rack. Main disadvantages of selective racks that it requires a large amount of space in the warehouse in order to store a high volume of products and density is sacrificed.

Pushback Rack System: In this rack system pallets are placed on carts located on an inclined rail system and pushed back by the lift truck operator. Pushback rack system allows pallets to be placed on both sides of an aisle which provide higher storage density than other pallet rack systems.

Drive In: Drive In rack configuration is another type of high-density pallet storage option in which lift truck operator drives inside the storage rack and moves the pallets on load rails. This type of configuration can vary from two pallets deep to 20 pallets deep. It is inexpensive relative to other racking systems but these systems are installed limited due to lack of selectivity, low productivity and vulnerable to damage.

Pallet Flow: In this racking system used in warehouses pallets are placed in the rear of the system on a set of rollers equipped with the centrifugal braking system. Pallet flow racks can vary from two to thirty pallets deep which provide very high density due to which it is the most expensive pallet rack option. This rack system requires good quality pallets and frequent maintenance.
