Any pictures of scissor lift for trailer dump

[Larry_Van_Horn]

I am going to start my next project of building a dump wagon. I have reviewed all the posts over the past year and have seen a lot. I am inclined to go with a 5 ton set of Kory running gear. I have reviewed designs of hydraulic cylinder placement (the haywagon pictorial in particular), and I am interested in how the scissor lift option works. Does anyone have any closup pictures of a scissor lift on a dump trailer?

I too am building a small combo wagon where a dump bed is one of the combos. I made the running gear and it is an "H" or "I" shape. Since it is a combo gear....dump bed, log splitter, etc. and with the shape I wanted to be able to easily remove the dumping mech and I didn't want to have an off center lift cylinder or two cyliders in a traditional dump wagon design so I designed my lift mech. based on a hydraulic floor jack.

Basically I have a four in. stroke horizontal cylinder that will equate to a 4x6 dump bed to about 45 +- 5 deg of dump. I am just starting to build the mech now. On paper it works we'll see as it comes together.

I don't know if I have seen pics on scissor style lift. There is a site that features old farm plans from Pop Sience, Mother Earth ect. I don't have the link but maybe someone here knows and can point you and something there might inspire.

Good luck on the hunt.

So based on my review of the pictures I have seen, it looks like contracting the cylinder expands the scissor. Is this right? If so I need to consider the pull force of the cylinder rather than the push force.

So, maybe a dumb question. Why you don't look for telescopic lift cylinder?

Larry, I have had several dump trucks and all of them expanded the scissor by extending the cyl. I don't know where you are but if close to central NC, I've got a telescopic cyl that someone can have

Nat,
Thanks for the offer, I am in upstate NY. I was thinking about a scissor lift since it would translate the lateral force of a cylinder into vertical lift. I have looked at a number of pictures and it appears that many use a standard 4 inch bore 24 inch stroke ag cylinder, but for the bed to lay flat, it seems like the cylinder needs to lay pretty flat and when it extends it creates quite a bit of lateral rather than vertical force. My objective is to use this to build a dump wagon (say 6 feet wide by 12 feet long) on a 6 ton Kory wagon frame. The telescoping cylinder idea is a good one. How short are they or yours? The one I have on my dump truck is really big.
Thanks again,
Larry

Here's the Harsh site diagram. http://www.harshenviro.com/hoists/rl-a05.htm

They make great hoists. Years ago I used to be able to buy from them. Now I have to go through a distributor, darn, I hate that. /forums/images/graemlins/frown.gif

Here's mine a home made 5x9 I bought at auction this spring. Note cylinder is 1 way so your tractor will need a large resevoir when dumping heavy loads My JD A (3 qt resevoir) will not fully extend & dump 2 yards of wet clay. Smaller stuff is ok.

Barry,
Thanks so much for your photo, that is most helpful.
