ChairMate The New Concept in Evacuation Chairs http://www.wheelchair-ramps.co.uk/ktp/ ChairMate will connect to most non motorised wheelchairs and transport the wheelchair with occupant downstairs with ease. Using caterpillar tracks and a fully controllable braking system ChairMate can be operated by the slightest of persons, irrespective of the wheelchair combination weight. http://www.wheelchair-ramps.co.uk/ktp/info.html I see that ChairMate copes with a person in a wheelchair but what about transporting an less able person who is not in a wheelchair? http://www.wheelchair-ramps.co.uk/ktp/faq.html
