converting equipment trailer to dump dual use

[case310350]

I have a 15k flatbed equipment trailer, would like to add a dump on to it. My plan is to build a dump insert that I could lift with a backhoe and drop it into the pockets of the equipment trailer. The trailer can carry 13k figure with the insert I could carry 11k material. almost 4 yards of stone.

I don't want to reinvent the wheel... so I figured maybe someone here may have made on all ready, or may know where additional information could be found.

I don't mind reinventing the wheel, I just don't want to reinvent the flat tire.

Most dump trailers are relatively short. Your insert might put too much weight on the rear of a long trailer when in the raised position. Semi-truck dump trailers have their wheels at the rear, so don't have that problem.

Kinda depends how/where he makes the pivot point, but it will be a TRICK to get it back far enough and get enough of a dump angle.
Even stone needs more than a few degrees to get rollin'

Semis are more different than that, the tractor "carries" one end, while the bogie carries the other.
It is more like a bridge, whereas a tag-along, with the bogie closer to the middle, is more like a teeter totter (-:

Your going to use the existing trailer as a frame and add a dump box with a lifting system at the front. Could be done but I am sure no matter how you construct it there may be problems with the " simple " on and off with the backhoe part. I see more problems than pluses. ( as a cheap alternative ) Buy an older dump truck, cut the frame and make a trailer out of it. You would be light years ahead.

How many loads of stone do you think you'd haul?

If it is less than 15 loads, and you didn't need to dump it in a nice neat pile, I'd say you'd break even on time of construction if you just built some sturdy sides to fit in the stake pockets and then used the backhoe to drag the rock off the trailer.

Not saying that this is the right solution, but I looked at a trailer I thought was 'thinking outside the box'. Was at a country fair on display with a trailer dealer. I'll do my best to describe it in a way you can picture it accurately...... looked online but didn't find a picture.

Take a dump body, and attach it to the equipment trailer sideways, just ahead of the trailer axles. It will dump off the side of the trailer. Then, have the side of the dump box closest to the axles either fold down, or remove. This is so when you aren't hauling dirt or mulch, it turns the dump box area into trailer floor space.

I'd speculate that with no tractor on the back, it would be tongue heavy with a load in the dump box..... but thought the concept was pretty neat. I thought it was made by PJ.... but couldn't find it on their web site.

Don't want to hijack the thread but I've been toying with the idea of a roll-off box for a trailer. I thought of laying channel iron down for the rail (remove the decking for the channel) and then building the box, 8ft long, 6ft wide and 3ft tall to accommodate the volume. Put heavy duty casters on the box and a clevis pin setup to secure the box while on the trailer. Continue the channel rails down the ramps, use your tractor to pull the box down the rails and once the end of the box was on the ground using the tractor to complete the tipping/dumping action by pulling up on the section still on the trailer. Someone build this for me and let me know how it works

More than "a clevis pin setup to secure the box while on the trailer".
That might keep it from rolling off, but the State DoT will be looking for what holds it DOWN as well, i.e. it needs to be secured from side tipping on curves.
Also, you would need some way to get the rolling box onto the trailer.
Roll-offs are pulled on and there is some sort of self aligning "device" to bring it into the slot - you would probably need a winch too.
Just thunkin' through it a bit (-:

Hmmm, pulling a box over to dump it ?
I suppose so, then you have to push it back.
A SHORT length of chain to a long enough back-hoe, or a boom on the FEL - need to not let it flip too far and need to put it back close to where it came from.

I have a yard where i sell product, stone, mulch, top soil, etc. So I figure I would make about 100 trips per year. If the business (weather) was year round I would take a different route. but with NYS reg fees, ins, and other costs, dual use maximizes efficiency while reducing costs for our short season. I am looking for a dump trailer, but used 12k is 4k+. My equipment trailer is 16' ( short), have the steel, and an extendable ram which I was going to use for anther project. so cost to build will be around 500.00 plus lots of time, although I do enjoy fabrication. Lifting on and off with the backhoe would not be a problem. I do that now with my truck lifting a easy dumper on and off.

Maybe a walking floor.....
