How many wheel chairs do you plan to transport at any given time, and the type of vehicle you plan to haul with?
I am thinking about hauling one wheel chair at a time. One major problem I hope to solve is clearing up a lot of space in the vehicle that is taken up by the wheel chair. In some mini-vans, the entire trunk space is taken up by the wheel chair itself. So, one proposed solution would be to make a little enclosed trailer to house the wheel chair only. I’ve considered making a ramp that is held by the receiver hitch that has the ability to lower/extend to the side of the vehicle; however, this does not keep the elements off the chair. Also, anything supported solely by the hitch would interfere with opening the rear hatch.
So.. my idea is to either modify an existing trailer, or fabricate one from scratch. As far as suspension, I am leaning towards leaf spring suspension, which I can adjust accordingly be removing a lot of springs to accommodate the light load of the trailer. I don’t think McPherson struts would work because they are usually built to not only absorb shock but to also hold the weight of an engine, which would make for a really rough ride for a light load.
Focusing on ways to make life easier, I would like the trailer to tilt to some degree. A fold-down ramp in the back could facilitate loading and unloading of the chair. I believe all loading and unloading could be done from the front even though there is no side access due to being enclosed.
Once I made it this far, I will devise auto-locking mechanisms of some sort to hold the chair so it doesn’t bounce around… and it should be something that can hold the chair when it is loaded ‘front in first’ (which I believe would be the easiest way to load the chair via the ‘normal’ pushing position.) Not sure how to approach this… I would assume any locking mechanism would have to be adjustable because not all wheel chairs are the same. At minimum I guess I could use dedicated ratchet straps to hold down the chair, but my first attempts should be to devise something that can lock and unlock quick and easy.
I plan to purchase steel from a local yard to make this trailer. Maybe use sheet metal to make the enclosure. I’m thinking about using oxy/acetylene to make all the cuts and MIG machine to do all the welds.
So this is my project. It will make people’s lives easier. It will give me that warm and fuzzy feeling on the inside.
