Parabolic suspension
Hapert introduces parabolic suspension – experience it for yourself
Parabolic springs create an optimal and constant load distribution across the entire trailer, allowing road irregularities to be absorbed more effectively. Even when fully loaded, parabolic suspension with axle shock absorbers ensures maximum comfort and stability of the suspension system.
In short, trailers with a parabolic spring axle guarantee:
- Excellent road handling
- Perfect stability
- Optimal road safety
- Maximum driving comfort

The trailer for heavier work
We know better than anyone how important it is that every load reaches its destination quickly and undamaged. Sustainable transport solutions that guarantee safe and stable transport, day after day.
For heavier work, we offer stable trailers in the 3,500 kg weight class: powerful heavy-duty models with a parabolic spring axle including shock absorbers. This type of trailer has been specially designed to transport the heaviest loads as stably and comfortably as possible.

Modern parabolic spring vs traditional leaf spring
The modern parabolic spring is significantly lighter and more stable than the traditional leaf spring. The spring characteristics of the suspension are also different. The characteristics of a parabolic spring are almost linear: as the load increases, the trailer suspension is loaded evenly across the entire spring range.
The classic leaf spring axle, on the other hand, is characterised by non-linear spring behaviour. Because multiple steel leaves are used, leaf springs are stiffer at the beginning of the suspension travel and only become more flexible as the springs compress further.
We have listed the most important differences for you below:
Modern Hapert parabolic suspension
- 30% lighter and more durable
- Smoother suspension system
- Maximum suspension comfort
- Even stress distribution
Traditional leaf suspension
- Multiple leaves per spring
- Stiffer suspension
- Take up a lot of space
- Higher risk of corrosion
