The plaque is the rack speaking. Learn to read it.
Direct answer: A load application plaque states two different limits: maximum load per beam level and total bay load, and the bay figure is usually lower than the sum of the level figures. Operators should work to the per-level value; a missing, damaged or outdated plaque — including after any reconfiguration — is an inspection finding.
What the plaque actually states
A load application plaque lists the maximum beam load per level and the total bay load, calculated for the specific configuration installed. Change the beam elevations or the pallet weight and the plaque figures no longer describe your rack.
The distinction matters because beams rarely fail alone — overloading one level transfers load to uprights, anchors and the floor beneath.
Making the plaque operational
Post the per-level figure where operators place pallets, not only in the office. A plaque nobody consults is decoration.
Re-issue the plaque after any reconfiguration, and treat a missing or damaged plaque as an inspection finding, not a cosmetic issue.
Beam level load vs bay load on the plaque
| Figure | What it limits | Who must respect it | Relation between them |
|---|---|---|---|
| Max load per beam level | Total weight placed on one pair of beams between two uprights | Forklift operators placing pallets | The figure operators see and work to |
| Total bay load | Accumulated load one frame pair (uprights, base plates, anchors, floor) carries | Rack engineers and floor designers | Usually lower than the sum of level loads |
| Plaque validity | Describes only the exact configuration installed | Warehouse management | Void after any change to beam elevations, components or pallet weights |
| Missing / damaged plaque | No authoritative limit is available | Site management | Treated as an inspection finding, not a cosmetic issue |
FAQ
Where should the load plaque be mounted?
Typically at eye level on an upright at the aisle end of the run, so it is visible to forklift operators before they place a load.
Does beam capacity equal bay capacity?
No. The bay (total frame) figure is usually lower than the sum of beam loads because uprights and anchors carry the accumulated load.
Who can recalculate after a reconfiguration?
The original supplier or a qualified rack engineer should reissue figures after any change to elevations, components or pallet weights.
