Aisle width
Short definitionThe clear width between racks that a forklift needs to turn. It varies with the type of truck.
To take a pallet from the rack, a forklift turns 90 degrees in the aisle. The aisle must be wide enough to allow that turn. A narrow aisle stops the truck from working. A wide aisle takes away storage space.
The width needed depends on the truck: a counterbalance forklift needs the widest aisle, a reach truck works in a narrower one. Which truck will be used in the store must be known before the racking is laid out.
