why not just use 1 ram and put in a linkage like on a digger bucket, that would half the amount of hydraulics you would need
i thought about that but I wouldn't be able to leave the ramps stood straight up rather than folded over back?why not just use 1 ram and put in a linkage like on a digger bucket, that would half the amount of hydraulics you would need
I cannot see how this can be done, as your drawing shows movement of more than 180 degreesI can get the amount of rotation needed without a linkage on just 1 ram
its because it isn't much over 180 degrees. the 1 hinge is 90 degrees the other is about 95 but if you allow for 100 for undulating ground?I cannot see how this can be done, as your drawing shows movement of more than 180 degrees
Measure twice, cut once, don't need a computer program to tell youtheres too much difference from the 1 hole to the next!!!! haha I used to trial ideas in lego though!
wish I had photos now I designed an "up and over" door on a tipper trailer, drew it all to scale in cad both up and down showing door onen/closed. then printed it out and pinned it to card to show as the tipper tipped it opened the door. then I drilled the trailer and used wood and rope to prove it worked before we set too and made it ... dad cut 2 holes wrong!!! I think it was 1120mm and he cut 1020mm so it still wasn't idiom proof!!!
thanks for info I will give that software a good go!
I'm going out now but I will alter this design to show over 180 degree rotation (I'm not saying it will be a lot over 180 though)I an sorry, but 1 ram with no linkage will never work on a 180 degrees never mind over that, so to use 1 ram it would have to have a linkage like the 1 above i posted
there used to be springs on my lowloader til i converted it to two rams, i thought it better to run a flow and return from the tractor and mount a spool at back so i could control them, thats the way i did it and ive always found it a good job.200 stroke is 360 centres closed and 300 stroke is 460 closed according to Ramko website/standard stock.
yes I thought that you could unfold them that way, I originally thought about putting them both on the same spool but I think it will be handy if its possible to leave the ramps stood straight up (just for instance you load a machine that's just too long to allow the ramps to fold over)
just debating whether to run 2 full sets of pipes to the tractor or do it like our artic where you supply oil to a valve block on the trailer and control the ramps from the ground.
I was spot on with my cardboard how do you think people made things before cad

i just put them to float for loading.
at cost you could go all fancy and go wireless...
your going to want some feet for that cheese wedge but id assume you know that.
if you made that all from scratch sir ill tip my cap to you, damn nice work there.
what lth is it, 12 foot ill guess.
personally id of went for 3 axles altho the way yours sits the axles look like they are just in the sweet spot.
I think I can show over 180 degrees on 1 ram.I an sorry, but 1 ram with no linkage will never work on a 180 degrees never mind over that, so to use 1 ram it would have to have a linkage like the 1 above i posted
non really, the ram wont foul on the change over of pivots as the ram will be the same distance from everything as it is in the folded position. I don't think the 1 ram is particularly good just proving it could be done. suppose the only thing you might say is you only have 1 ram to buy? personally i think standard rams are cheapThe problem is with one ram like that you will have to power it against the floor, in float it will try and sag in the middle. Even then, track something like an excavator up those ramps and it will put massive tensional forces on those rams. Then when folding it will flop about, first it will bend at one point, then halfway through there could be a bang and that pivot will straighten and the other will bend. It could fowl and mark / bend the rod during this.
What are the benefits of one ram?
no it cannot be done with 1 ram,
you will need 2 rams 1 to work each part of your ramps, that should be easy to work out
