Not plans, but an interesting idea to give a starting boost when using a direct action cylinder.

I wouldn't bother unless you are using two axles or a dually. The cost vs reward is pretty low unless you go big. I want a small 4 ft by 6 ft dump trailer for my 1026r but I'm not prepared to pay for it until I get a mini ex to load it 
I'm still thinking about making a dumping flatbed for my ram 2500 though. I guess it depends on what scale you are building. They make pickup dump conversion kits but they are overpriced and the beds warp fast!
Are you building a trailer or converting a truck?

Angling a cylinder and raising the dump body off of the frame is how I would do it. If you want two cylinders look at how articulated dump trucks are built. Their cylinders start out at about 30 degrees to lift huge loads with fairly small bore cylinders. Semi truck dumps sacrifice bed space for multi stage cylinders but those cost too much imo.
Nope, no pulley deals, gotta keep it all low.
I picked up this trailer on Camp Pendleton.
It is a generator trailer, I guess these trailers
are throw aways after the generator is mounted whereever
they put it. New it was over $3200.00. I paid $225.00.
Notice the brakes...VERY Cool it is.
I have been vasilating
back and forth for months trying to dream up a bed
I will be happy with. For now I am thinking to just get
a dumping running gear going and then go from there.

You could keep it low by mounting the pulleys from front to back and having a link on rollers that gets pulled backward to push the bed up.
Should work well especially if you add a helper spring to get it up 6" or so.

Do the front wheels steer? $225 WOW! Wish they were close to me, I'd have one to pull with the Kawasaki Mule.

Our typical tax dollars at work. The tires and brakes are worth tripple that. I am surprised some huge buyer of surplus doesn't get everything and mark them up 6,000 percent. When I was in the Marine Corps they still had prop airplanes over seas.
Great start for a dump trailer. A hoist and some 10 guage sides / floor and it will last a life time.

Hope you are good at backing up. I had a h=== of time backing one and I have backed boats around for 30+ years. Nice trailer! We the people sure paid to much for it if they paid $3200. If I were you I'll just make one, they are easy to make and you have a good frame to start with. You are 1/2 done..

this is a nice light weight hoist, Stealth Dump Trucks (757) 890-4888 looks easy to copy,
http://www.stealthdumptrucks.com/hoistassyopen.JPG
you would not need the lifting hing for dumping over a bumper,
the hoist on my one ton uses the swing hing or pivot idea,
(another Idea would be to (you said you wanted to keep low), make a roller chain lift on the front using a long stroke cylinder or hand pump jack like used on engine lifts, by running the roller chain up over the sprocket, (as done on a fork lift one can lift the entire length of the cylinder extended, now to keep it low one could make it pivot and lay on it side or forward with not in use, http://img.ehowcdn.com/article-new/ehow/images/a05/4o/4f/forklift-works-800x800.jpg
or if one can find a multi stage cylinder and just mount in the front of the box.

I would think if the base is made solid, and if the box does not move side to side, and you had a good sized rod, with a unit with two idler sprockets on it or even a solid shaft with sprockets on it, so each side would have to lift the same. (I think the key would be to find a cylinder with what would basically be a over sized shaft),

I think that to keep it low I would go with a sissors style, they lift pretty well. What are you going to power it with?
I work in a gravel yard and see alot of the electric ones become a problem real fast. My 2cents I would use a gas engine and set it up like a log splitter hydrualics.
Have fun and keep us up on the project

I have an electric power pack on my one ton truck and it is original 1978 and has done well over the years, the only problem I have had is about about 30 years I had to clean out the oil tank as the oil separated and there was gobs of grease that would plug up the screen in it and thus it would not lift the hoist, cleaned the oil and tank up and replace with fresh oil and works like a champ again,
(probably should change oil ever 10 years or so would solve that problem),
but if your pulling the trailer with a tractor just hook in to the tractor hydraulics, with quick connects,

I think the reason people have so much trouble with electric dump trailers is that they are infrequently used and almost never maintained kinda like my $700 lawn mower that always has a plugged up carb since I don't use it much.
