Parabolic suspension
Hapert introduces parabolic suspension – Experience it for yourself now!
Parabolic springs ensure optimal and consistent load distribution across the entire trailer, thereby better absorbing road irregularities. Even when fully loaded, the parabolic suspension with axle shock absorbers, ensures maximum comfort and stability of the suspension system.
In short, trailers with parabolic spring axle guarantee a:
- 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 cargo reaches its destination quickly and unscathed. Durable transport solutions, guaranteeing safe and stable transport every day.
For heavier work, we supply stable trailers in the 3,500-kilogram weight class: powerful heavy-duty models with parabolic leaf springs and shock absorbers. This type of trailer is 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 considerably lighter and more stable than the traditional leaf spring. The suspension characteristics are also different. For example, the characteristic curve of a parabolic spring is almost linear: as the load increases, the trailer suspension is evenly loaded over the entire spring area.
Conventional leaf springs, on the other hand, are characterised by a non-linear spring characteristic: because they use multiple steel leaves, leaf springs are stiffer at the start of the travel, and the trailer’s suspension only becomes more supple as the springs compress further.
We have listed the main differences for you below:
Modern faltering parabolic suspension
- 30% lighter and more durable
- Smoother suspension system
- Maximum suspension comfort
- Equal voltage distribution
Traditional leaf suspension
- Multiple blades per spring
- Stiffer suspension
- Take up a lot of space
- Higher risk of corrosion
