Very Narrow Aisle Pallet Racking System:
In a very narrow aisle (VNA) pallet rack system, pallet racks are placed closer together than other pallet racking solutions because they are loaded and unloaded using a side loading fork lift truck; enabling aisles to be narrow and ensuring that storage space is used efficiently. The amount of product stored and warehouse footprint is maximized. VNA aisles are typically 1.8 to 2.2m wide, providing 44% more floor space than a selective pallet rack system.
Features
- Clear aisle of 1.8 to 2.2m
- Emulates characteristics of selective racking
- Turret trucks retrieve and put away pallets from pick and deposit (P&D) stations at the end of each bay of racking
- Turret trucks require wire or mechanical guidance down the length of each aisle
- A separate forklift delivers and picks up pallets to and from the P&D stations
- Order picking machines may pick from pallets, but not at the same time as turret trucks
- Only one machine in an aisle at a time
- Utilization: 90%
When do you use it?
- When you have a high SKUs with relatively small quantities per SKU
- Where you want good space utilization
- When you have large amounts of goods moving and out
- When you want to improve the storage density within your warehouse
When not to use it?
- When you can’t afford to two machines operating
- When you have limited budget
- When you have a high movement velocity and need two machines working in the same aisle at the same time
