We need the room to build two larger trailers so this one needs to go. brand new, just built, never used heavy duty ATV/Utility trailer.This trailer is well built and is practically maintenance free.It will never rust out as the frame is made from all galvanized steel and the floors, walls and tailgate are made from aluminum diamond plate.2000lbs capacity.4'x8' inside dimentions. .Much greater quality then trailers purchased at any of the big name spots. NO TAX AT MOTOR VEHICLES. $1600 firm if interested call Mark at 209-1596 or 431-9928       |

your shackle mounts are incorrect. They need to go towards the axle until you get 45degrees. (That is 45deg. the wrong way.) It looks like it needs to be moved about 6" towards axle. Remove spring hanger, drill 2 new holes, and bolt it back on in the right spot. the leaf is not acting as a spring in that configuration. You can dazzle the lookie-lou's, but not me.  You need to fix that b4 it hits the road. |

I have never seen it that way, and I am referencing 4x4 experience. Moe knows what he is talking about...i feel kinda stupid, but i thought that was a big safety issue about to hit the road. I even called buddy.  How can the leaf flatten and lengthen under load like that? The diagram doesn't make sense. |

The spring can still enlongate when loaded like that, except in this case it will go from a shallow angle pointing towards the angle to 90, maybe beyond.
We have to worry about spring droop and the shackle going negative. If the shackel goes negative beyond 45 degrees then we could be into a situation where were bending/braking leaves. Jeeps and such weigh alot more than the typically loaded utility trailer.
I suppose on the trailer if the angle is steeper than 45 degrees theres less of a chance it will invert and more of a chance of moving towards 90 and beyond. Trailers also generally are not noted for the flex.
Ive always wondered why shackels on leaf sprung cars were the way they were and not like on the trailer shown above, if it really softens the ride one would think its desireable.
P.S. nothing to feel stupid about, like most things in life theres more than one way to skin a cat.

As far as the diagram making sence its poorly drawn in that it looks like the shackle is supposed to swing on the ned we would assume is fixed.
What its saying is if the shackle is raked towards the axle the spring rate is stiffened as an assembly compared to leaves rate only. If raked away from the axle then the spring rate is lesser than the packs rate.
It also shows the limits at A and B which appear to be 45 degrees from the datum line.

Just wanted to say thanks to Jan for showing concern and to Mostheman for clearing up the issue.I couldn't sell something in good conscience that i knew was unsafe.This is the forth trailer like this we have built but the first one that we are offering up for sale.My father just retired from 35 years as a metal worked with DND and hes just trying to stay busy so he dosen't go nuts with bordem.
So don't go running for the hills if you see this trailer in your rear view,its perfectly safe!!
Thanks again Mark.

No problem,
Looks like a nice trailer.
I'll be looking for a utility trailer for hauling the jeep and other stuff soon,
tandem axle with brakes on both axles, would it be something he's interested in?

better safe than sorry? lol i kinda went a little overboard.....but i really thought that was dangerous. I have very little trailer experience, so I'm mildly embarrassed i jumped the gun. Glad Moe caught it quickly. As you were! |
