HAPERT PARABOLIC SUSPENSION

HAPERT introduces parabolic suspension - Try it out now!

A parabolic suspension system gives an optimal and constant weight distribution over the entire trailer and helps compensate for any unevenness on the road surface. Even if the trailer is fully laden, the parabolic suspension with axle-mounted shock absorbers provides maximum driving comfort and system stability.

In short, trailers with a parabolic suspension axle have a guarantee of:

  • Excellent road holding,
  • Perfect stability,
  • Optimal road safety,
  • Maximum driving comfort

TRAILER BALL-THRUST

YOUR TRAILER AND BALL THRUST

Ball thrust is the force that a trailer applies to the tow bar of a car via the coupling. The amount of pressure exerted on the tow bar will depend on how the trailer has been loaded. For example, a heavy weight positioned near the drawbar could result in excessive ball thrust, while positioning too much of the load at the back of the cargo bed will result in insufficient ball thrust. A negative pressure may be the case too, if an upward force is applied to the tow bar. All of these situations are the result of incorrect loading, resulting in an increased risk of skidding and swerving.

This makes ball thrust one of the most important criteria for the road-holding of trailers and the road-handling of the vehicles towing them. HAPART Aanhangwagens bears in mind the need for optimum ball thrust when developing trailers too - when considering the distance between the axles and the centre of the wheels, for example.





IT'S IMPORTANT TO REGULARLY CHECK THE TYRES ON YOUR TRAILER

For your safety and also to make sure that your trailer is reliable, it is important that you regularly carry out thorough checks to establish the general condition of your trailer and its tyres. A good set of tyres and a stable load increase road safety significantly.

TYRE PRESSURE AND TYRE WEAR

The tyres on your trailer are the only parts of the trailer that are in direct contact with the road surface. This explains why the condition of your tyres largely determines a trailer's grip on the road and its road handling. Tyre pressure and tyre tread in particular majorly affect the safety of your means of transport. With this in mind, we advise that you check the tyres on your trailer for the following every two weeks:

  • Tyre pressure
  • Tread depth
  • Irregular wear
  • Cracks in the sidewalls

If in any doubt, always contact your Hapert Dealer.

Brake maintenance

Well-maintained trailer brakes play an important role in your safety and give you peace of mind. That is why we recommend that you visit your Hapert dealer once a year and have your trailer serviced. Learn more about how to maintain the brakes on your trailer by watching the videos below.

Checklist:

    1. AVOID OVERLOADING

    2. Secure the luggage properly

    3. Distribute the luggage evenly

    4. Make sure the ball thrust is correct

 
    1. Handbrake safety cable

    2. Plug and socket

    3. Trailer handbrake

    4. The trailer's lightning

    5. Maximum speed





  • Know what to do if your trailer starts to sway.
    1. do not increase your speed;
    2. take your foot off the accelerator pedal and push down hard on the brake pedal;
    3. steer straight until the trailer stops swaying;
    4. slow down and continue driving until you reach the first place you can park.
