Drive-in & Drive-through Racks offer the ability to store a large amount of similar loads in a smaller area. Selectivity is sacrificed but the storage density is outstanding. Drive-in racking can store up to 75% more pallets in the same space than selective racking – depending on the application. It requires fewer aisles and has better cubic storage.
Drive-In Racks allow a lift truck to enter the rack from one side to pick up or pull out pallets. This is done because pallets can slide backwards on a continuous rail. Fork lifts drive into the rack to access pallets two or more deep. You are limited in the depth of storage for a particular bay by the size of your facility.
Drive-in:
This is a Last-In, First-Out arrangement.
Drive-through:
This is a First-In, First-Out arrangement.
Basic Components
Frame & Upright :
Same as in Selective Picking Pallet Racks
Pallet Runner :
Pallets are kept on a pair of runners which run throughout the depth of a system. The runner’s side profile acts as a guide for pallets
Runner Brackets :
These are mounted on the upright frame and support the pallet runner
Joining Piece :
Used to join runners
Beams :
Beams are direct load carrying horizontal members used to connect the vertical frame from top laterally, to make it a cohesive structure
Top Runners :
Members to connect frames from top longitudinally and not for loading purpose
Top Bracings :
Diagonally connected to top runners for better stability of system
Guide Rails (Optional) :
Fixed to the ground with the help of anchor bolts and provided to guide fork lift. Fork lift also needs to be attached with side guide rollers
