"NEW" Structural Cantilever Rack
Capacities and Warnings

CANTILEVER COMPONENTS

(diagram 1)

1. WARNING! Arm and Column Capacities are affected by factors including, but not limited to the following:

• Load distribution
• Distance between columns
• Number of levels per column
• Type of product being stored
• Floor conditions
• Anchoring

• Weight of Load

2. Correct Loading

• Loads must be evenly distributed in order to attain the capacities listed.  (see diagram 2)
• Uneven loads reduce capacities by 50%.
• Floor Anchors must be used in all base and column "anchor holes"  to attain capacities.
• Type of floor anchors required is determined by slab construction and therefore
  must be determined by customer's engineer.

Correct Loading	Incorrect Loading

3. Determining Maximum Distance Between Columns
Distance between columns should not exceed a dimension equal to:

Length of the Load (L)
# of Columns supporting the load

(diagram 3)

Standard Bracing Sizes are:  48" or  60" (Horizontal distance between arms)

In Diagram 3, the distance between the columns (d) must not exceed:

      Length of the Load (L)                                                     15 feet
# of Columns supporting the load    =                  2 Columns        =           7 1/2 feet

Distance Between the Columns must not exceed:   7 1/2 feet

A. Arm Capacities

• Each 48" x 4" cantilever arm can support 3,500 pounds.

• The total weight  stored on all of the arms on any 1 column cannot exceed the capacity of     that column.
• In diagram 1, if the load spanned the entire horizontal length of the cantilever section, each level of  arms could support a load weighing up to 14,000 pounds. (load supported by 4 arms x 3,500 pounds per arm = 14,000 pounds)
• Arm capacities subject to factors described in Section 1 thru 3.

B. Column Capacities

• 12' tall Cantilever Column can support 10,200 pounds per side.
• 16' tall Cantilever Column can support  8,800 Pounds per side.
• Column capacities subject to factors described in Section 1 thru 3.
