## Content

## Very Narrow Aisle Rack

In Very Narrow Aisle (VNA) Pallet Rack Systems, the space separating parallel rack units is greatly reduced, and pallets are placed and retrieved using a side loading fork truck. This minimizes the size of the aisles between rows of racks and can reduce the aisle space by around 40%. These pallet rack systems are available in original slotted or tear drop style columns and can be used at heights of up to 40 feet.

Provides higher density with 100% selectivity. Uses lift trucks designed to work in narrow aisles

Advances in fork lift trucks that can operate in aisles less than five feet wide have made VNA storage racks possible. The pallet rack systems provide a significant reduction in floor space and generally reduce costs of warehousing.

Pallets in very narrow aisle systems are 100% selective. With VNA racking, access to stock is uncompromised and the amount of product stored in the warehouse is maximized. It is an effective method of increasing pallet storage within a given area.

Columns & Beams:

• The capacities shown in this table are for static load conditions only.
 • The Frame Capacity Chart gives static load capacities based on the specified "Unsupported Length" of the columns (Vertical Beam Spacing).

WARNING: Due to the system-based design approach of the current RMI Specification, the use of static load capacities are no longer appropriate. Load ratings can only be provided through a system analysis which accounts for configuration of the system, static loading, seismic parameters, stability requirements and the interaction characteristics of the various system components. These capacity tables should only be used as a "starting point".

## Very Narrow Aisle Rack - Virtual Showroom

Very Narrow Aisle Storage is a special application of selective rack. Aisles between rack bays are reduce to approximately five feet wide creating additional storage space. These systems great improve storage density, while maintaining 100% selectivity with access to every pallet position. VNA systems are used for both full pallet and carton storage. In either case, special lift equipment; such as turret trucks or order pickers are commonly used. For carton storage and retrieval applications, a special Man Up lift is used to hand pick items.
