Anyone Built a 3pt Dump Box w/ Hydraulics?

[PLanger]

I was thinking about building a 3 point dump box with a hydraulic cylinder for the dump function. Figured I would ask here if anyone has built one - no sense in reinventing the wheel. Primary use will be hauling in blocked firewood from the woods.

I am currently looking into building a 3 point carry all. I am planning on using the hydraulic center link to dump it.

Yes I did, it's my weight box and for hauling stuff. I just put gravel in it for a weight box then dump it when done. I did a single lever to unlatch after these pictures were added.

Hyd toplink is probably your best bet for dumping. Set your brackets that the cyl is fully retracted when the box is level to get the most amount of tilt when dumping.

Leejohn, nice work. I especially like the slots for the hinge bolts. I may have to borrow that idea for my 6x10 hyd dump wagon.

I built this 10 years ago. Not a dump box, but rather a dump carryall. Bed is 3' X 6'. I built it to haul a little of everything, but wouldn't be that hard to put sides on.

I have the same set up on my dump trailers. If you do it like that, when dumping just don't back up after it's about 1/2 up only move fwd slow until empty. It well push the tail gate up and of the slots, if it doesn't come all the way off then the tail gate can't close and it bends the brackets. It's no big deal but I have done it 2 times and the 1st trailer was made in 2003.

I like this design. Looks like a person could get far greater tilt/dump angle than a hydraulic top link. Any more close up pics of your design? Thank you.

That does bring up a good question. How much tilt is needed?

I've got one of those three point reversible tripping scoop buckets that will roll over upside down (a pain when it does)
It's used for carrying cut wood out of the woods, and moving rocks, soil, stone etc. There is never a problem dumping any load, 4 foot wood slides clear as I drive away.

Then I've got a tipping garden trailer that barely tilts 20 degrees unless it's over a bank. (which it often is)

The trailer needs help to discharge a load. The scoop bucket will clear set up concrete ;-)

I would say that somewhere around 35 degrees of tilt is enough for anything but wet clay.

I bet there are other considerations and opinions on the details. ;-)

Leejohn,
That looks fantastic. What did you use for the floor and sides?

I forgot, I well check tomorrow.
