Palletised Storage: Adjustable Pallet Racking (APR)

Adjustable Pallet Racking (APR) is the most widely used storage system for all palletised and non-palletised loads. Racking construction consists of end frames and horizontal beams, and the height of the beams can be adjusted to suit the height of pallet loads to be stored.

Single or double-sided runs of racking are separated by aisles that can be sized to suit the customer’s forklift trucks. The basic design of APR is for flat pallets, but accessories are available for storing particular unit loads, such as drum stoppers, decking, and channel supports.

The advantages of APR are:

• High accessibility to all pallets;
• Designed to suit all load sizes and available space;
• Use of standard forklift trucks;
• Easily installed and repositioned;
• High occupancy rates; and
• Cost-effective.

The disadvantages of APR are:

• Fork truck aisle gives access to only two rows of racking, hence, the building space utilisation is low; and
• For racking heights above 8 m, a chemically treated flat floor is needed to stabilise the racking with the load.
