At over a hundred quid for a jockey wheel I don't think so.

I fitted one of these to my Triton 420

I had one of those Clasohlson wheels, it was great on my Puck but when I put it on my Familia it ripped its self to bits. I put it down to the motor mover and the large height with the rubber tyre. The Alko wheel hasn't the same kind of rubber depth which I'm hopping will not have the same effect.

The 'C' in Clasohlson stands for C47, it's a Dakota wheel

sounds like just the ticket , does the tube fit the clamp ok?

Nah, Easy mate,....Only need to do it once with the same towcar and van.
!,...Find out Max towball weight for vehicle,.........Value=Skg
2,..Align jockey wheel to face rear and lower to ground.
3,..Measure centre of van wheel to centre of towball receptor space on hitch,......Value=L1 cm
4,..Measure centre of van wheel to point of contact of jockey wheel on floor,........Value=L2 cm
Calculation is: Multiply SxL1,...and then divide the answer by L2....The answer will be your max noseweight in kgs.
Write it in permanent marker somewhere on the frame and I have drawn a red line on the gauge itself.
Five minutes, requires Tape measure, calculator and marker pen.

Well the noseweight will vary from caravan to caravan before you use the Alko.
So you must need to calibrate it to a particular van.

Zitat

what's with all this calibrating stuff anyway

---

Normally the calculation is from the axle centre to the coupling socket centre (of the A frame) ................so all quoted weights use that measurement

When you weigh from anywhere else other than the coupling socket centre the leverage is different so the result is wrong unless you compensate for the different distance

Alles klar

Your max noseweight is determined by the towing vehicle manufacturer surely? But what's with all this calibrating stuff anyway - is it really necessary as there's non of this with the standard nosewheel and let's face it - a wheel is a wheel at the end of the day.

To complicated for me thats why i stick with what Eriba deemed the item to do the job, don't have a problem with mine on gravel But then again i canif necessary lift the front of our Troll, and i've seen people use a piece of carpet to stop it, if indeed your jockey wheel digs in. I always make sure mine is lowered below the lugs

Noseweight explained

The only thing it seems not to mention is Minimum noseweight ...........................I'm sure I read somewhere that it must not be less than 25Kg and must never be negative.
