The scale of the bearing load indicator is positioned so that the displayed value approximately corresponds to the actual support load on the tow ball coupling. This allows the bearing load to be easily checked before each journey – an important contribution to safety when driving with a trailer, especially with regard to the 100 km/h regulation.
Additionally, the sprung wheel fork provides more comfort when manoeuvring in the uncoupled state. The inner tube acts like a shock absorber and reliably compensates for unevenness.
A TÜV registration is not required. The scale ranges from 0 to 125 kg. The outer tube has a diameter of ø 48 mm.
