TWIN AXLE QUESTION

[John_374564913]

I have a twin axle caravan the ex-works nose weight is 81Kg

My car nose weight max is 75KG

is it the same principal used for reducing nose weight on a twin axle as a single axle or is it more complicated being a twin axle

 

[Lutz]

In principle the same applies, yes.

I must add to Lutz reply,

With a TA, the height of the hitch is even more critical when measuring the nose load. Due to the interaction of the twin wheels suspension, the actual nose load can vary quite significantly with just a small change in the height of the hitch.

The nose load must be measured with the hitch at exactly the same height from the ground as when it is attached to the car and ready to roll with all passengers and luggage.

interesting point

my nose weight gauge has quite a lot of travel when taking the weight. how would you compensate for this

Hello Robert,

Assuming the nose weight gauge is actually shorter than the vertical height you need to achieve, you need to pack the gauge up until the correct height is made.

If the gauge is too long, then unless you can cut it down, then I'm afraid its not suitable for your purpose.

I have serious reservation about the majority of commercially sold so called nose load gauges;

Most are fixed length and thus probably do not meet the need for the height requirement.

The scale graduations are not really fine enough to resolve to the Kg level,

Most are not calibrated, so their accuracy is doubt.

some that fit to the top of the tow ball raise the hitch and thus will under read the actual nose load value.

Using bathroom scales with pole and load spreader is probably more accurate, and you can actually calibrate the scales fairly easily.
