Trailer ABC – A for Adjustable (Parking) Supports

Function of the adjustable supports

They stabilise the trailer during the loading and unloading process. The supports can be used whether the trailer is coupled or uncoupled. They provide additional stability and, when used correctly, prevent the trailer from tipping over.

The supports can be divided up into two main groups: fixed supports and spindle or crank-operated supports.

Good to know!

Supports must always be returned to their original position before setting off on a journey. Driving with the supports in a working position is prohibited.

Please also make sure that all screw connections are properly screwed tight before setting off.
