What does the dynamic load factor cover?

It scales the static weight for accumulation pressure, starting surge or a full line of product. Use the factor your conveyor supplier specifies; 1.25 is a reasonable screening value for light accumulation.

Where do I get the rated conveyor load?

From the frame, roller or chain rating in the manufacturer's documentation. Use the lowest rating in the load path, because the weakest component sets the limit for the section.

Why is load against rating useful?

It places the total on the rating's own scale. At 90% the section is nearly used up, and the 10% headroom disappears fast when product weight, accumulation or friction changes.

Does the runtime basis change the load?

No. Load is a weight, not a rate, so it does not change with hours. The V1 runtime row is dropped because it moved no output; use the load ratio and the headroom for the review.

Conveyors calculator

Conveyor Load Calculator

Estimate the total moving load a conveyor section carries from its base product and carrier weight and a dynamic factor. Compare it with the rated load to see the headroom left.

What this calculator does

Total moving conveyor load from the base product and carrier weight and a dynamic factor, checked against the rated load.

Formula used

Total conveyor load = base product and carrier load × accumulation or dynamic load factor
Load headroom = rated conveyor load − total conveyor load
Load against rating = total conveyor load ÷ rated conveyor load × 100; blank at zero rating

Inputs explained

Base Product and Carrier Load: Product, carriers and belt or chain weight on the section.
Accumulation or Dynamic Load Factor: Multiplier for accumulation pressure or starting surge.
Rated Conveyor Load: Frame, roller or chain rating the section must stay within.

How to use the result

Best suited to adding product to an existing conveyor, checking roller or beam ratings, sizing an accumulation zone load.
A single total load for the section; point loads at curves, transfers or supports need their own check. The rating comparison is static; fatigue, shock and take-up loads need the manufacturer's method.

Current U.S. benchmarks

The U.S. has 21,668 machinery manufacturing establishments employing about 1,086,146 workers (Census County Business Patterns, 2023).
