The correct adjustment of the ball height for trailer couplings

The correct adjustment of the ball height for trailer couplings

Guide for motorhome and commercial vehicle owners

The towbar is an important device for those who travel with RVs and commercial vehicles. However, not everyone realizes the significance of the right ball head height. Discover why it is so critical and how to set it correctly.

Correct set of ball head

Why is it crucial to get the ball height right?

Legal requirements: According to EU regulations, the towbar's ball head must be between 350 mm and 420 mm above the ground when the vehicle used for towing is not loaded. These regulations are crucial to ensure consistent safety on the roads.

Safety risks: Using the wrong height of ball head for the towing device can result in losing control whilst turning or braking, as the trailer won't be pulled horizontally. What's more, when the trailer is properly attached, it won't touch the ground, preventing any scratches during towing.

Efficiency: The correct level of towbar’s ball head guarantees that the tyres will wear evenly and optimises braking by ensuring that all the trailer's wheels have even contact with the ground.

When should you check the height of the towbar's ball head, and how can you do it effectively?

Regular checks: Check the towbar’s ball head height before every trip. However, if you don't tow frequently, once a year will suffice.

Checking: To check towing hitch’s ball head height, put your vehicle on a flat surface. Use a tape measure to measure the distance from the centre of the coupling ball to the ground. Then, compare this value to your vehicle manufacturer's specifications, towbar’s specifications, and the legal requirements.
