    • A collapsible wheelbarrow includes a rigid front bracket, a wheel rotatably secured to the front bracket, and first and second handle arms pivotably attached to the front bracket. The first and second handle arms are laterally pivotable about first and second pivot axes respectively. The first and second pivot axes are each spaced apart from the axis of rotation of the wheel. Preferably a clamping device removably applies a clamping force between the first and second handle arms and clamps a rigid tray between the first and second handle arms. The tray is preferably interconnected with the first and second handle arms to permit relative movement in a lateral direction and to prevent relative movement in a forward rearward direction. Preferably, the front bracket has spaced apart upper and lower walls and the first and second handle arms extend between the upper and lower walls.
