Engineers and MacGyvers needed to help disabled flyer

[Let'sgoflying!]

I have accepted the task of rigging up a lift, which could raise & lower a person about 30" to/from the cabin floor of two different aircraft which have airstairs.
-no wheelchair, the person can stand & walk slowly.
-there will be two identical lifts; one at base and one at outstation (there are no other destinations for this person).
-it needs to be a battery powered lift; there is not 120v handy. It could be charged when not in use. Doubt a handpump would be accepted.
-it needs to be rolled over asphalt, concrete, some of it not perfectly smooth - up to 50' each use but not with a person aboard - hand-rolling is fine. Some of the wheels likely will need a brake for stability.

I imagine a 3'x3' platform no more than 6" high at its fully lowered height, which has a 3' x 18" walking surface extension welded on, designed to enter the cabin by only about 6".
Handrails all around which are shaped to avoid a/c damage.
I think it should be configured to have the extension rest on the cabin floor.

Person gets aboard, handrail is locked in place. Lift is raised to a few inches above cabin floor.
Wheels are unlocked, platform rolled so that extension enters cabin 6". Wheels locked. Platform lowered to contact cabin floor. Pax enters a/c. Lift removed.

Where to start? Grainger?

Considering that thing is going to have to be extremely heavy in order to support a person. I'd look for an existing Manlift to modify. We has a few single person lifts that would work (after modification) because you have to step up into them.

This is what we have at the airport. No power necessary, it moves through a series of cables and pulleys and is easily operated by one person.

I would get a Powered wheel chair scooter for the base. Remove chair and replace with a motorcycle lift from harbor freight. Or smaller same idea would be the transmission jack. Replace jack foot pump with 12v actuator... think gate opener.

Or cheaper would be to add locking casters to the transmission jack. Add platform. Add railing. done.

I flew for a regional and they had various models of this exact thing thru the years as a lot of smaller airports did not have jetways. Beats me who manufactured them. Google it or check eBay.
