Default Wheelchair Modifications

This thread is about a different set of wheels than we are all used to. I am looking for a wheelchair which can climb stairs.

Here's the situation: A standard wheelchair available in the market has two big wheels to steer/drive and two small castors/free-wheels under the footrests to add stability. While good for travelling on flat surfaces, it would be a pain to carry it up or down a staircase.

I have come across trolleys for carrying heavy goods, designed with a set of three wheels fixed to a hub in a star-topology, which can make it easier to haul the loads up/down the stairs. I am looking at modifying a standard wheelchair in a similar way. It would be accompanied by two adults, so the wheelchair-bound person is not required to operate it in any way.

What I need is information on who can do it in/around Mumbai or Pune, and if this has ever been attempted.

Research: I have researched on the net for a similar solution. While I found a couple of similar concepts, one of them from IIT Mumbai, I have no clue if anyone can actually provide a working prototype.

Check out the images below for an idea of what I am talking about:

The company that I work for got one for emergency evacuation of pregnant and diabled personals. I think its from UK and there was a mention from the concerned personal that it costs near to 1K GBP

The manufacturer is www.spencer.it.

The ordinary wheelchair costs around 4k at my place. I am looking for someone who can design a set of tri-wheels as shown in the images, which can be fitted under the footrests of the chair. My guess is this modification should not cost more than the wheelchair cost itself.

I checked the link, but none of the transport chairs seem easier to move up/down stairs. Still, thanks for the link. The chair design itself is quite innovative.
