Wow, that second design with 900 lbs is really amazing and so simple. Awesome video!

That's pretty cool. I have an old handmade childs rocking horse that uses a similar action.

Interesting design, but it looks like your back and arms would get a lot more tired than using an old fashioned wheelbarrow. The motion is all bend and lift. With the heavy load his design has a longer lever to minimize bend and lift force while doing your work through more distance. Its interesting, but I'm not going to give up on the wheel yet.

This is not my video. Just found it on the web. Man there explains that he only raises and lowers the wheelbarrow and it walks itself, it consumes less energy.

If you could get it to go up stairs, that could be valuable some places. I am not giving up the wheel just yet, either.
