LOAD CAPACITY & SPECS
Uniform Load vs. Concentrated Wheel Load: What’s the Difference?
NOTE: This is general guidance, not a substitute for your specific platform’s rated capacity. Always confirm both uniform load and concentrated wheel load ratings on your platform’s capacity plate or manufacturer documentation, never assume one rating implies the other.
These two numbers measure different things, and a platform rated highly for one isn’t automatically rated the same for the other.
Uniform load is weight spread evenly across the surface. Think of pallets sitting statically across a deck, the total weight is distributed broadly enough that no single point bears a disproportionate share. A uniform load rating tells you how much total weight the surface can carry when it’s spread out this way.
Concentrated wheel load is weight delivered through a small contact point. A forklift doesn’t distribute its weight evenly, it delivers the full combined weight of the vehicle and its load through the small contact area of each tire. That concentrates far more pressure on a small section of decking than the same total weight would if it were spread across the whole surface.
Why the distinction matters practically. A platform can carry a high total uniform load on paper while still being vulnerable to decking damage or structural stress from repeated concentrated wheel loading. This especially applies at high-traffic points like the transition between the platform and a trailer bed, where wheels cross the same narrow strip repeatedly throughout a shift. This is a different failure mode than simple overloading, and it’s why the two ratings are tracked separately rather than treated as one number.
Both ratings need to account for your actual equipment, not a generic assumption. A heavier forklift, a higher axle load, or a narrower tire contact patch all increase concentrated wheel load independent of how much total weight is on the platform. Confirm your forklift’s specifications against the platform’s concentrated load rating specifically, not just its overall weight capacity.
