Dump trailer build 14K lbs.

[fnieto]

I considered putting the carriage bolts from the inside out, but was after cleaner look. The locking nuts are fairly low profile with about 2-3 threads showing. The solid round bar that runs along the outside will provide plenty of areas to secure a tarp without the tarp chaffing on the carriage head.
Thanks for you input during this build.

I run a tarp on the inside. I lay down a tarp on the bottom and sides and then fill when it is brush or dirt. Helps with removal and cleanup. Then fold it over the top for traveling. And I had the bolts looking pretty and then changed it.
If you are mostly hauling stone, it may not be an issue.
I am scrutinizing as I sold my old dump and will be building a new one soon. Just waiting for the pesky cold to go away.

You do this on a dump trailer? You have to dig out the tarp after you dump?
I'm not sure I understand the your process.
I tarp brush (not required in Tucson) over the load, once at the dump, I un-tarp dump load and leave the dump ASAP. I'm always learning something new, so if you could explain further, I'm all ears.
Thanks again for your input.

I run on a smaller scale. And I had low profile dump. So when I dump, there would always be stuff left. Pull on tarp and now trailer is completely clean. I've had full loads of leaves and spent more time cleaning trailer than I did loading it by hand.
Now you can see why I had asked about your low dump height. A low trailer is great when you are manually loading, not so good if yo want a high dump pile.

I am looking at building a dump trailer. Have a pair of 5200lb axles, so the load will be around 8-9K after trailer weight.

What is the advantage of using a hoist over just 1-2 cylinders direct mounted. I see commercial trailers around here with both, but for building it seems that the cylinder option is much cheaper. It will be for around the house use only so speed isn't a major factor. Load would be since I know I will overload it at some point.

Using a hoist vs a singl/double ram set up gives you the the most lift for the amount of stroke. Hoist set ups are compact, less oil (smaller resivuor) and the geometry is maintained though out the stroke. Smaller dump trailers work well with singl/double rams but require good bracing at the mounts (point load). Rams need to be long to achieve a good dump angle and can hang low when bed is down. The hoist kit company (Premium Supply) offers seven models from PH 310-PH 630 (this build used a PH 516). I have built a few and prefer the hoist hands down.
I hope you got the answer. My brain fails me at the comuter keys at times.

Nice build.
I did notice that there are brakes on one axle only! Pretty scary, if even legal, for a 14K trailer.

2 schools of thought here!

With 2 wheel brakes there is less likelihood of it jack-knifing if the brakes lock up.
With rocker equalizer suspension the brakes should be on the rear axle so brake torque increases traction. [brake torque is greater than weight transfer]

Rear brakes only are less likely to lock up, front brakes only can easily lock up

Most builders get this wrong ,so some lawmakers [Aust] mandate 4 wheels brakes to get around this issue

Good eye my friend, a second set of brakes have been added since the picture was taken. The axels are brake ready so not much effort to install. I did also install and wire up a break-away switch.
I also took the trailer on a operational check, after checking brakes, lights and tow tracking, we worked up to 65 mph with excellent results.
This was the first larger project constructed in my new shop. Man, do I enjoy the new space.
Thanks for all the comments and inputs guys.

The photo of the completed project looks great. I am glad to hear that you added brakes to the second axle. About 15 years ago I bought a 7K car trailer that only had brakes on one axle. I added brakes on the second axle after about 10 years of use, it seemed to give the expected 100% increase in braking especially in high fade situations such as coming down a steep highway exit ramp with a stop light at the bottom.
My trailer was made in Mississippi which, at least at the time, had very lax trailer equipment requirements. It didn't even come with the center marker lights on the rear (102" wide trailer). Fortunately the trailer it self was well made and I still have it after 15 years. It has been to both coasts, MA to CA, OH to FL without any problems.
