Oh, I've got to interject here!

The Chinese wheelbarrow is a wonderful piece of appropriate technology, but isn't really as you have described.  First, it only has one, very large, wheel.  Not two.  The reason is that the wide diameter of the large wheel both creates a lower angle of attack upon small obstacles such as rocks as well as provides for a larger surface contact on unimproved roads.  Two wheels, even close together, would negatively affect the ability of the handler to balance heavy loads across the left-right axis.  But it's also a human powered road vehicle, not designed for no road at all.  The Chinese wheelbarrow does not serve the same function as a Western wheelbarrow, but is more like an ancient pickup truck.

You're absolutely right Creighton.Quite early on I distinguished what I was describing as being in the Asian style, by which I meant a central rather than end positioned wheel, but not, strictly speaking, a Chinese wheelbarrow.

Then I  talked about how in my urban setting, I use slightly modified wheelie bins, and how they can share some of the same good traits as the chinese wheelbarrow.

If I remember correctly, I was making the point that you basically got the vehicle to a balance point where very little weight was actually being supported by the person, and no infrastructure needed to be moved before it could be useful.

This photo shows spring loaded caster with plastic wheel replaced by double flanged steel gate wheel. Spring stops caster flopping side to side to easily . Same at other end, again pulling to center of trolley. There are better ways of doing this but I decided this way was simplest, cheapest, minimal work. The operators on the smallholding recon it works fine.

Chris, if you want to post a youtube video, just click the Youtube box at the top of the screen and paste the URL for the video into the box that pops up.  Here's the video I think you are talking about:

I was thinking about the whole track-moving thing and came across a question: what about segmented track that rolls up for movement and easy deployment, or storage in winter, where applicable?

Perhaps hinged track segments on hinged base segments, attached so that, for rigidity in deployment, the track would slide forward half a segment length before locking into place, so the joints don't line up.

Such a configuration could be rolled up into a toroid shape and rolled around the landscape at need.
