⧉Image Agricultural Tools: Wheel-barrow With Ball-bearings

This wheel-barrow originating from Hunan Province—weighing 25 kilos—is made from camphor wood and has a length of 193 cm. It has a loading capacity of 200 kilos and can be constructed easily at a low price. Its center of gravity is considerably low, thus easy to lift. In its original version, the axis is wooden, yet if ball-bearings are added a significant growth of transport capacity can be achieved because the bearings reduced pushing resistance by 80%. In addition, if a rubber-coating is added to the wheel the wheel barrow can be used on public roads without damaging them.
