Ok it's a Torsen style axle and it's shot! So hay you needed to caugh up about $500 anyway.

Looking at the picture, as long as there is not a cross member in the way, I think this will be easier then I had first thought. The torsen cross beam is not inline with the centerline of the axle hub. By making a bar that would step up and bolt onto the existing monting flanges you will create a bolt on mount for the air bags to make the coach hight adustable. Add a cross bar forward of the current cross bar about 12 inches as a point to anchor some pivot points. With a drop axle that would have the potential to drop the bottm of the trailer down to 10 inches with a door sill hight of 14. normal coach is around 20 inches.

Well, here would ba a way to get into the trailer, made of aluminum, of course. It is installed on a Frankenstream currently for sale on Ebay. The ramp should only weigh around 30 pounds or so, at least you would be able to get the chair into the trailer.

Tire inflator

If you decide to go the air bag route, you could also add an automatic tire inflation system. If you deflate the tires when parked and re-inflate them for travel, you could lower the chassis another 4 or 5 inches. You would need to add some axle skids to keep the tires from deflating totally and crushing the sidewalls.

Hello all…

Hey bredelo…thanks for the sketches..those were great but there are a couple of issues we would have to look at-
-curving c-channel on an arc
-the width of the channel would have to b wide enough to allow front and back tires on

hey toaster…I am not understanding a couple of things-
-u say my axel is bad….y…..i had it looked at in AZ and they said it was ok, then we towed it all the way to OR with no problems…
-have u ever installed drop axel on a trailer….does it put more wear on the tires..

thanks for the feedback and could use more

rich

Bad axle

I agree with toaster about the axle. Our 63 Tradewind has a shot axle. Bad axles cause much more vibration and shock to the trailer. The axle is the suspension system also. This is all explained at Inland Rv's web site.
http://www.inlandrv.com/axles/
it is very informative.
Since the axle needs to be replace how about this idea.
Longer swing arms on the axle. Then have airbags installed like the original shocks. With deeper fender wells you could deflate the bags and lower the trailer very low. The longer arms allow much more travel. The amount you lower it depends on the airbags. Or hydraulics like on low rider trucks.

My 59 is drop axle factory. I was hoping yours was also. It would have made this even easier. I guess 62 is the last year of the drop axle.

Check out the info on InlandRV.com about checkign the style axle you coach has. One thing Andy points out is the arms should have a little downward angle. Yours don't have any sitting and I asume that unless your storing items in the coach then it is actually lighter right now then packed travel weight.

Also look at one of your earlier posts about the floor digram you were asking for. I linked a air bag suspension on a 71 Chevy truck that is very simular to what I am suggesting as a way to do this. I also had a link of a drop axle to give you an idea of what I am talking about.

I'll try to get a clear shot of how our 59 is set up and maybe that will clear up what I'm talking about. It's hard to explain but one of those once you see it deals "Ohhh now I get it".

Hey Rich,

A good place to start then would be to know the total width between the innermost point of the front wheel, and the outermost point of the rear wheel. (I'm assuming that the front wheels are closer together since hips are wider than knees.)

At that point, you'd know the minimum width of the track you'd need. C-channel is what I was thinking of (my imagination tends to use off-the-shelf pieces) but it certainly could be done custom. If custom - I'd think the curve would be even easier to get right, since a proficient metal worker would likely build the bottom of the channels, and then weld on the sides.

Let's get a measurement on that width when you get a chance. I'm not a metalworker by any means, but it would help us further visualize what would be reasonable to create. I think this could be a pretty exciting part of the project, since it would make your trailer exceptionally personal.
Brad

Edit: Just typed in "bending c-channel" into google and got this company:
http://tauringroupusa.com/

On one of their pages they have this neat picture of what looks like bent c-channel:
Enjoy!

pic of our ramps

ok guys
here is a pic of our ramps we purchased at a metal shop
they were cheap and work great at this incline, so we know if this works good, whatever we design will work better
with this, rich needs a little boost into the airstream, which makes it hard for him to be independent
going down is no problem........
unless he has had a litlle too much to drink (ha ha)

just a thought ...instead of trying to reinvent the wheel what about the wheelchair ramps used everyday on the road ford vans have'm and i've seen them on a dodge caravan... those are small vans that generaly are rated as half ton or less so the isue is not weight... what objections would you have that...

How about a frame mounted under the belly pan full width of the coach. Put your ramps in this frame, pull the ramps out just enough to get the wheel chair on the ramp. place an air bag under the ramp and inflate this pivots the ramp up meet the floor height with a ramp angle that can be negotiated by the wheel chair. I visualize a pan (wheelchair size) that is pivot mounted on a pair of arms so that when the air bag is inflated, the pan tilts as it is raised on the arms that are pivoted about the centerline of the coach. Simple and does not interfere with the door or affect the looks of the interior decor. I am retired Mech P.E. Call me at 503 628 1387 and I will arrange for sketches if you want. Ernie Preedy Hillsboro OR. Right in your neighborhood.

I really like that one, JanP. It's like the lift system on the back of panel trucks, or the larger UHaul vans. It would come out from under the trailer like a cash register drawer, then lift up to become flush with the trailer floor.

It makes so much more sense than lowering the whole trailer on airbags that I can't believe I didn't think of it before. It may actually require removing a section of belly pan, or raising the whole trailer (giving it a bit of a 4x4 Jeep look,) but in the long run I think it'll be a much cheaper and more sensible option. As long as it stores under the very center of the trailer when fully retracted, it will stay balanced side to side. As for when it's extended, it won't have Rich's full weight on it for extended periods of time.

I'd guess as long as the whole system was bolted, welded or otherwise conntected directly to the frame from underneath, it could be the least intrusive and least visible solution of all, and making nearly no difference aesthetically to the trailer.

Now, it ain't as much fun as my amusement park S-curve ramp, but you can't have it all.

Just my two cents. My boyfriend Brian is in a wheelchair (power) too. One of the main reasons for buying the AS was to have an accessible home away from home too. We were going to use an aluminum folding ramp similar to the one you have. However the design we were looking at is more similar to the ones used for loading quads into trailers, they fold. It seems to me the problem is rise and run longer ramps are needed for easy entry and exit (must be independent). Unfortunatly thats where I see the challange, the longer it is the more convoluted it must be to fold, limited space with the door and existing entry. If any of you watch moster garage an example would be the Mercedes they made wheelchair accessible (didn't quite work well enough). Our van has a kneel system, which is basically a winch that compresses the rear shock, since AS's don't have that system I don't see how it would work.

For us the most important thing right now is being able to go where we want. We are both in our 20's. If I have to fold and unfold a ramp until I figure something else out, it will be ok for a while

Our friend in Springfield, OR has one in a Dodge van, complication the floor pan is cut out and lowered 4" and the van is taught in kneel another 4" when the ramp is extended.
