Would it be possible to install a dead-mans brake on a wheelchair?
I have been calling around and wheelchairs do not seem to come with a dead-mans brake. With that i mean the brake found on airport trolleys: you let go the trolley stops.
The problem that needs to be solved is that we are often pushing a grown man on a steep hill. If the person pushing the wheelchair were to stumble and release the chair, it would probably end in death as the road is not only steep, it is also full of bends and has irresponsible, speeding cars and buses.
Would it be possible to install one made from off-the-shelf parts?
I have seen this: https://casterconnection.com/dead-man-brake-system.html
But this is part of a set of small wheels, i'm not sure if that would be the right solution. If i replace the front wheels with this braking pair, would the chair not flip over?
