Important notes about the above table:
- Maximum load per shelf on RTFAP & RTFBP is 7,500 lbs.
- Capacities based on interior usage.
- Capacities are for selective racks only.
- Capacities are applicable for non-seismic use. For assistance on Seismic
zone applications, contact Cisco-Eagle.
- All columns/posts must be anchored to an adequate concrete floor, as
required by RMI code.
- Capacities are based on installation in a plumb condition.
- Capacities are total per upright frame, assuming equal loading on both
posts.
If any of the above conditions do not apply to your application, or
if you are unsure if they apply, do not utilize this table. Consult
with Cisco-Eagle for design information.
- Safety Factor = 1.8:1 per 1997 RMI code.
- Based upon 55,000 PSI steel.
- Other frame designs and capacities are available. Contact us for
information.
- Capacities do not include the weight of the rack system itself. Deduct the
weight of frames, beams, decking and accessories.
- RMI code recommends use of optional accessories (such as Steel Guard
Rails, Column Protectors, etc.) to reduce damage to frames.
How to Use This Table:
- Calculate the maximum load per bay; number of levels x load per level
(supported levels only)
- Determine the maximum distance between levels, or the distance from the
floor to the first beam level, whichever is greater. This dimension is the
"vertical beam spacing" referred to above.
- Using the vertical beam spacing, as determined in Step 2, follow the
appropriate row towards the right until you find a capacity equal to or
greater than the capacity required, as determined in Step 1.
- You may wish to choose an even greater capacity upright, for additional
abuse resistance.
- Verify the adequacy of your floor to support these loads.
