"Wheelibarrow" evens the route bumps out by adding a linkage to the normal wheel-barrow.
In developing countries human labor is common in construction works. Wheelibarrow uses two simple adaptations to a normal wheel-barrow to reduce pressure on spine. First and foremost it evens route bumps out by adding a simple suspension system. It is composed of an idle linkage, half the wheel radius in length, that smoothens the shock when climbing any bumps.
Moreover, adding a pivoting handle grip together with a simple gravity activated brake to the conventional wheel-barrow, Wheelibarrow will make the dumping process easier and more ergonomic.
