Building an 8遅16 gooseneck dump trailer

Nick,
I still think your old Ford is the coolest build ever!

If you look at the engine picture, you can see the gear drive Holset air compressor on my Ford.

Hay Dude, not trying to be "negative Nancy" but looking at that load of hay, it would appear to be too wide to re-latch your drop down side on the deckover dump. It would also appear to have way too much force against the front bulkhead and tailgate without the side wall support.

Thats because I space the bales about a foot apart. Butted together, they can fit in an 8 space. Ive already done it. I would want to have strong as possible sides though.

Thanks Bud, it was a fun ride back in the day. Too much work now

Okay, my bad, I didn't notice they were spaced, I just noticed they were about flush with your big trailer, I assume it is 102".

Yeah I open the lower rows a little to make the upper rows a bit more stable.

I notice a few of the fold down sides trailers have a key way built into the sides to add rigidity. I am concerned with bending a side while sliding bales in though.

Would a standard 8' wide deck over with solid sides work at all? Then you could get the big axles and 20'. Load the first tier through the tail gate and the second tier over the side?

Nah, I really want the fold down sides for bales, pallets, etc.
Like this one with 3)8k axles and 16’ long.
I might see if I can get by with 2) 8k axles.

I dont understand these trailer ratings. My Kaufman has 2) 16k axles, but it’s rated for 38,500lbs. Thats 6500lbs of pin weight.
The dump trailers are all rated by the sum total of the axle weights or even less.
For example, PJ has a dump with 3) 8ks and they rate it at 21,000 not 24,000 or more which is LESS that the axles added together. But they offer a 2) 8k axle version at 16,000lbs. :confused3:
I don’t know what Load Trail will give me with 3) 8k axles.

Triple axles do an excessive amount of tire scrubbing in turns.

And two trailing wheels bend the swing arm of the first axles when pushing around a kerb stone. Tri axle torsion is rubbish, tri axle leaf sprung (straight axles) is ok, but tandem is better.

I think part of the GVW rating considers two or three axles. It might not be reasonable to expect one axle to carry the weight of three, but is okay for one axle to carry the weight of two. This is in a momentary situation where the ground is uneven. Dexter does not recommend a three axle torsion, because of this. With springs and equalizers it can still happen but chances are way less.

Saw a Lamar tandem dump today. It looked good. 7ga floor. Paint looked way better than my Kaufman. Really getting the itch to make a deal.
Wonder if I could get a tandem 9k rated at 20k GVWR built?
10k duals are out because of folding sides.
