Forklift trucks drive into lanes on racking specially built to provide support to the pallet along the pallet sides. Stacking often to 10 metres high and 4 or 5 but occasionally even 10 pallet positions deep. This system can provide a very dense storage capacity, often low in access and rotation of products.  As the truck enters the racking, special precautions apply to ensure the compatibility of design between the truck, pallet, load and the racking. Flat floors are advantageous.Usually the rack design incorporates a stability structure at the rear of the rack and therefore drive in indicates single access from one side. Drive through requires this same stability to be provided by a variation in design.
