Narrower paths are significantly cheaper to build and maintain. The article has some images of the narrow paths used. A single track vehicle is more usable on bad roads of any width. Such vehicles only need to dodge the potholes and dropoffs that would cause extra energy use and might be entirely impassible to a multi-track vehicle.
This sort of effect is seen with bicycles in urban areas. A single narrow broken kerb can create a new bicycle route where there was none before. This superiority of single track vehicles is sometimes used intentionally as a filter to allow the passage of bicycles and prevent the passage of cars. In my city there are raised medians on some bicycle routes with a pair of narrow cuts (for 2 way bike traffic) to allow the passage of the intended traffic across a road without creating another route usable by cars and trucks.
- Markoff 8y agoyeah but allows less load because it's more difficult to keep balance than with two wheels cart
- glenneroo 8y agoMaybe initially, but like any skill, practice makes perfect. Considering the distances traveled and loads carried (up to 6 people!), I would guess the average Chinese wheelbarrower learns rather quickly how to not drop goods/people. It would be interesting to know how often accidents happen with the Chinese vs the European versions though. My experience says that European/US wheelbarrows are just as, if not more easily tipped when fully loaded. I've seen it happen often enough and I've had it happen to me. Regarding maximum load, the article states: > In other words, when the load is 100 kg, the operator of a European wheelbarrow carries a load of 50 kg while the operator of a Chinese wheelbarrow carries nothing. He (or she) only has to push or pull, and steer.
- Markoff 8y agoexcept i was talking about two wheeled cart, not European wheelbarrow regarding load and one wheeled will be never as stable as two wheeled no matter what are your skills, you need to balance it in all directions while two wheeled need to be balanced only in two directions
