A standard wheelbarrow, with the wheel at the front, places about half the weight of the load on the operator. A load-centered wheelbarrow places the wheel in the center of the load, shifting 90% or more of the weight to the wheel instead of the operator. This allows the device to be used for distance hauling on narrow paths.
ECHO developed a design that is scaled down to use a bicycle wheel. Details about how to construct and use this design are in ECHO Technical Note 101.
The wheelbarrow design can be modified to meet local needs, conditions, and materials. If you make modifications or have other design ideas, please share them with us and others here!
