retrofitting aluminium trailer

[rideglobally]

i decided to post here, need all the help i can get. i am retrofitting the Alumna 6810 trailer into an enclosed toy hauler for a side car motorcycle, increasing max load from 2200 pound to 6000 pounds capacity. (the 2200 pound Dexter axel, wheels and tires is for sale, see classified) trailer will travel off roads. here are some picture of the build so far. i have replaced the axel to 6000 pound and move the fender to accommodate the bigger tires.

first question;

not sure what the terminology is for this but i am trying to figure out the angle when the tow vehicle and the trailer are on a dip. pls see picture, those two wood structure represent angle of the tow vehicle and trailer. is there a formula? average? i am trying to figure out if i should put a slant on the front top of the trailer. there is 60" distance between the tow vehicle and the front of the trailer. the trailer and the tow vehicle are 8' tall. thx

I'd have never thought of that problem. Sounds like you have a good idea, sloping the front panel of the trailer.
The bike and sidecar cant' weigh #6000, or do they? Sounds like a pretty huge number. Single 6 bolt is only rated at
max #3500 where I live, with 2" ball.

Gotta second that, up-rating the axle & rolling stock doesn't up-rate the whole trailer. It's still a trailer designed for a 2200 lbs load. It just now has a 6k axle under it.

"Pitch" is the term used in aircraft for that attitude relative to horizontal. So what is the max Pitch angle, and does it decrease in a Pitched turn?

you can get a Aluma 6810 trailer that are rated at 5200 pound, on this one i am also retrofitting the trailer for the load.thx

the side car only weigh 1500 pound, but the trailer will also include shower and water tanks etc.. thanks

ok trailer gurus, can you help me out with how to determine the pitch on the top of the trailer, to prevent the trailer from hitting the tow vehicle on a dip. thx

8" tall from the top of the tongue or 8'tall off the ground? I can do the math but I need to know the height of the trailer from the top of the tongue.

Assuming that the top of the trailer is 72" above the tongue and the tongue is 60" the angle is the inverse of the tangent of 60/72
or roughly 40*

thanks, it is 6' from the top of the tongue and the length of the tongue is 60". thx

That would be an isosceles right triangle and the angle to hit top of trailer to rear of truck is 45*

 

[rideglobally]

ok thx

I still wish your take off axle was closer, I would have bought it

Nice Sidecar, I recognize that foot peg bracket anywhere...

The trailer is awesome too, very nicely done..
