Abstract:

A load carrying cradle includes a pair of wheel assemblies, each of which accommodates a bicycle-type wheel rotatable therein. Each wheel assembly includes a pair of horizontal slots, one of which is positioned in front of the wheel with the other positioned behind the wheel. A pair of lengths of standard-size framing lumber are slidably positioned within the horizontal slots with the lumber extending between the wheel assemblies to form a load platform. The wheel assemblies are movable toward and away from each other on the lumber to accommodate various sizes of loads. Each wheel assembly also includes a pair of vertically oriented slots to accommodate a corresponding optional pair of vertically oriented pieces of lumber. The vertically oriented lumber allows the cradle to carry and support taller loads than would be possible with the wheel assemblies alone. The horizontally oriented slots are positioned substantially below the axis of rotation of the wheels for enhanced stability and the cradle has a turning radius equal to the spacing between the two wheels.
