If you were to raise the attach point of the rod side, closer to the ramps, that should give you what you need. You may have to adjust the cylinder side towards, or away from the rod then to get the positions you want. Of course, that will lessen the lifting power of your hydraulics. But, I don't think what will be a problem once you get hydraulics hooked up.
Jimmer, you are the man.After 2 days of messing with it I had come to the conclusion that I could have all the way up or all the way down but not both.After your post I gave it one more try as you suggested but I moved the whole square cross tube up about 4 inches.It worked perfect.I have complete up and down travel and never moved the cylinder.Thanks a lot.
Now for making them adjust for different width vehicles.
The hydraulic ramps are finally finished thanks to Jimmer, 3RRL and others. I dropped the pressure down on the pump until they operate nice and smooth.
Thanks you guys for the inspriation. Video of RAMPS - Photobucket - Video and Image Hosting and some more pics.
Wow Steve,
Great job on those ramps!
You sure did some clean work there. No more back pains either. Thanks for sharing that cool video, I'm sure there are a bunch of us guys who could use a set like that.
I skimmed through and think some one else had kinda suggested this. I think this would be the cheepest and quite simple of a solution.
In the pic i added 2 red lines reprasenting square post that would be detachable from the ramps. the kinda purple lines would be where you could run the cables. probably having a pully like device welded at the wheelwell area would be best.
you could go with 1 or 2 winches and adjust the lenghts to make the lifting force of appropriate level. another thought would be to use a block & tackle system that would lift both gates with 1 winch. It would just require a long cable to do it.
Kendrick, your idea was very good but because of the wooden rails and a possible clearance problem when loading cars I had to go underneath with hydraulics to make it work. Would have been easier to do though.Thanks again for the advice.
