Procedure
1. Find out the floor load rating of the location where you plan to install the storage system.
Important: If you do not know or are not certain about the floor load rating of the installation site, be
sure to check with the building engineer or another appropriate person.
2. Determine whether the floor load rating of the location meets the following requirements:
• The minimum floor load rating is 342 kg per m² (70 lb. per ft²).
• Use the table to determine the required side, front, and rear weight distribution area for the specied
floor load rating. The side dimensions for the weight distribution area have a maximum of 76.2 cm
(30 in). If the side dimensions required to meet a specied floor load rating are greater than the
maximum allowed, then the floor load rating is not listed in the table.
• The maximum per caster weight that is transferred to a raised floor tile is 450 kg (1000 lb.).
3. Using the following table, complete these steps for each storage system.
a) Find the rows that are associated with the storage system.
b) Locate the conguration row that corresponds with the floor load rating of the site.
c) Identify the weight distribution area that is needed for that storage system and floor load rating.
Note: If you are unsure about the correct placement and weight distribution areas for your storage
system consult a structural engineer.
