Dump trailer

[Nat]

I sold my old dump truck because I can't justify the expense of tag and insurance for no more than I use it, and it was awfully slow on the road. Since I need a dump often I thought I would build me a dump trailer.
It seems like there is a lot of interest in dump trailers so I thought I would build it on this website as well as in my shop. I went yesterday and bought the steel. I got 6-20' sticks of 5" channel, 2-20' sticks of 2X2X1/4" angle - 4X8'X11gaflat metal, and 1 piece of 1/2"X4"X4" flat bar. Total cost was 642.00
I went on Wed. and bought the pump/valve/resivoir/motor, hitch and tongue jack. The cost for those was 497.00
I started this morning cutting the steel to length. The trailer will be 6' X 12'

Here I have the sub frame welded together sitting on the bucks It is just a 6' X 12' rectangle butt welded together

I always make an A-frame tongue because it stops the frame from racking. The tongue is made of 5" channel the same as the frame. Here is the tongue with the hitch and jack mounted

In this pic it shows how far the A-frame goes back under the front of the subframe, and how I terminate the A-frame. I also have the main frame welded together sitting on top of the subframe as it will be when it is finished. the main frame sticks back 1' behind the subframe

The hinge will be in 10" from the back. Since the main frame is 1 ' longer than the subframe the back of the trailer will get closer to the ground when it dumps, but that won't be a problem. I will make the hinge out of the 1/2"x4" flat bar, with the hinge pin being 1 1/4 rod, cause that is what I already had. It shoul be more than enough. Here you can see the overhang on the back.

Here is a shot of the Pump. I got it at Northern, it's a 1800 psi, 1.6 gallon per minute pump with a 20' cord set. It will be power up, and gravity down.
The cyl is a 4" 2 stage cyl that I have had for years. The first stage has a 24 " stroke, and the second stage is a 3" stroke with 28" of travel. I'm not sure why the 2 stages don't travel the same distance, but it realy doesn't matter to me anyway.
I could have gotten a 4" X 24" cyl from Northern for 109.00, but the store closest to me doesn't stock it so I would have had to have them order it and no telling how long that would have taken. A 4"x 24" cyl would work good, but the 2 stage will give a steeper dump angle so that can't hurt, and like I said I already had it.
Here is a pic of the pump and cyl

I'll keep you posted as I get more done, but that isn't bad for 5 hours work. Later, Nat

Great Job. Making me drool wanting a dump trailer. I'm planning on some jobs this spring of selling composted zoo doo, and dumping it would certainly be easier than using a shovel!

The trailer I have to haul my tractor boast of the A frame being intergral to the rails, they have been notched and welded to form on continuous piece. Your way is easier to fab.

Keep posting!

Very interesting picture essay. I'm looking forward to seeing the rest. I really like project sequences. It's a great way to learn from others on TBN.

Thanks again,
Cliff

Nat.....
Did you buy a set of Plans or are you winging it? Why 6x12? What are you using for cutting the Material & Welding with? I built a 25' Race Car Hauler years ago & it was a real bugger to keep square; everytime I welded it the thing kept moving on me. How do you keep it square? What's your shoe size? /forums/images/graemlins/cool.gif Got carried away didn't I? Thanks
