Drive-Thru racking systems offer a highly efficient method of storing large quantities of similar loads by allowing the forklift driver to enter the rack system and place the load on structural rails, much like the Drive-In systems. A Major difference between them is that Drive-Thru racks can provide first-in/first-out storage, while drive-in racks only function as first-in/last-out systems.
Drive-Thru racks allow a lift truck to enter the rack from either side to pick up or pull out pallets. Loads are supported by rails attached to upright frames, and lift trucks are driven between uprights to reach pallets. This is done because pallets can slide backwards on a continuous rail.
Selectivity is sacrificed, but storage density is improved since many pallets are stored and are available through a single pallet position.
Drive-Thru rack systems are ideal for any location where you need to store as many pallets as possible in a small space (such as cold storage).
The design of drive-thru requires in depth specifications of the forklifts being used because the rack bay opening and first tier must allow space for the lift truck and the pallet load.
