.....The maximum nose load (S value) a tow bar can accept should be include on a data plate fitted to the tow bar. That is the maximum value, because the tow bar manufacture as evaluated the design.
You only need as much nose load that will keep the outfit stable, Most outfits do not need to go a high as 100kg....
You mean this prof ....
But the tow bar should have a data plate specific to the model its attached to.
No it shouldn’t, and won’t, and Craig’s picture is a perfect example.
The towbar will have a data plate relating to itself, i.e the towbar only, and nothing relating to the vehicle.
I’m a little concerned here that focussing on the towbar data plate and nothing else may mislead the OP. For example, a towbar with an “S” value of 105KG could be fitted to a VW UP!, but that car will have a significantly lower maximum towing noseweight than this, and it is always the lowest value which must absolutely be respected. Hence my tongue in cheek editing of Craig’s previous post, highlighting that there is a difference between the towbar’s “S” value, and the vehicle specific maximum
To give you another example, the manufacturers official maximum noseweight figure for my Passat is 90KG, yet my VW approved towbar states 100KG on the data plate. Again Prof, it is always the lowest value which must be respected, also taking into account of course that stated by the Caravan or trailer manufacturer.
