## High Density Pallet Rack Systems

#### High Density Pallet Rack systems maximize storage space and minimize storage costs.

When storage space is at a premium or extremely costly to operate, high density pallet storage rack systems can increase usable space by up to 75 percent. Distribution operations that require high volume order fulfillment or freezer and cooler applications are some examples of when a high density pallet storage rack system would be required.

High density pallet storage is available in a variety of options to take care of any particular storage and distribution application.

#### Features:

-  First-In, First-Out Storage

- Last-In, First-Out Storage

-  Improve Density with few SKUs or Many

-  Systems for Pallet and Carton Loads

-  May Require Special Lift Equipment

-  Multiple decking options

#### Applications & Options:

-  Distribution Centers, Industrial, Retail, or Warehousing

-  Freezer and Food Storage

-  Truckload Quanities of same SKU items

[Drive-In Storage Rack Very high density first-in, last-out storage arrangemnent ideal for few SKUs](products/high-density/drive-in-storage-rack/)

[Push Back Pallet Rack Many SKUs accessible from the aisle with 3 to 6 pallet positions deep of the same SKU](products/high-density/push-back-rack-storage/)

• 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".
