Calculate axle and coupling loads.

Quickly assess how equipment added to a caravan affects its centre of gravity, axle load and coupling load.

Determining caravan center of gravity from drawbar nose load, axle load and reference distances

Caravan centre of gravity and load distribution.

Use the axle centre as the reference point for all distances. Enter positions towards the coupling as positive values and positions behind the axle as negative values.

Distance from the coupling point to the axle centre, in mm.
Mass of the caravan before additional loads are added, in kg.
Default percentage of the unladen mass applied to the coupling.

Core calculation steps.

1. Enter the base values

The coupling-to-axle distance, unladen mass and initial coupling load ratio determine the starting moment.

2. Add equipment

Position loads such as batteries, water tanks, furniture and equipment relative to the axle centre.

3. Review the result

Assess the centre of gravity, axle load, coupling load and coupling load ratio together.

Let us assess your caravan project.

We can support the planning of load distribution, technical documentation and type approval for your project.
