Describe the vehicle geometry
Use the relevant wheelbase, kingpin and axle positions for the selected configuration. Geometry matters because the same cargo position can produce different reactions on different vehicles.
Logistics planning tool
Truck Center of Gravity Calculator
Truck Center of Gravity Calculator brings cargo weight, cargo length, loading position and truck geometry into the same LogicCalc workspace as route, timing and transport economics. Review longitudinal center of gravity plus balance and axle-load warnings before quoting or dispatching.

How it works
How it works
Use cargo weights and loading positions to estimate the longitudinal center of gravity and how the load is shared through the vehicle geometry. The goal is not merely to fit the cargo, but to see whether its position creates an unhealthy balance or axle-load risk.
Place cargo at realistic positions
Enter each item’s weight, length and loading position. Heavy items have a much larger influence on the combined center of gravity than light freight.
Move the load and watch the balance
Review the calculated longitudinal center of gravity and balance or axle warnings. Shift heavy freight forward or backward and recalculate until the distribution is operationally sensible.
Typical use cases
What you can use Truck Center of Gravity Calculator for
Use the center-of-gravity view when cargo position matters as much as total weight, especially with concentrated or uneven loads.
Load repositioning
Test whether moving a heavy item changes the load distribution in a safer direction.
Axle balance checks
Detect cases where total payload is acceptable but the longitudinal balance is poor.
Heavy cargo planning
Plan concentrated machinery, coils or other heavy pieces whose position strongly affects axle reactions.
Practical example
Example: two heavy cargo items
If an 8,000 kg item is centred 2 m from the chosen reference and a 6,000 kg item is centred 8 m away, their combined cargo center is about 4.57 m from that reference: (8,000×2 + 6,000×8) / 14,000. Vehicle geometry then determines how that combined load is transferred to the support points and axles.
Frequently asked questions
Truck Center of Gravity Calculator FAQ
Why is center of gravity important if total payload is legal?
Because the same total cargo weight can create very different axle reactions depending on where the cargo is placed. A legal total weight does not guarantee a good distribution.
Does moving one heavy item really make a large difference?
It can. The heavier the item and the farther it moves, the more it shifts the weighted center of gravity and therefore the vehicle reactions.
Is this a substitute for certified axle weighing?
No. It is a planning model based on the dimensions and positions entered. Final legal compliance should be verified with the actual vehicle data and, where required, real axle weights.
Does the calculation cover every type of vehicle stability?
No. The page focuses on the modeled longitudinal balance. Lateral and vertical stability, dynamic effects, load securing and other safety considerations require separate checks.
What to verify before loading
Balance calculations are only as good as the geometry, cargo weights and positions entered. Treat the result as a planning aid, not a certification.
- Use actual vehicle geometry and cargo positions; small assumptions can matter when heavy items are concentrated.
- Verify legal axle and axle-group limits for the countries and vehicle combination involved.
- Check load securing, lateral and vertical stability and real axle weights separately where the transport requires them.
