Swivel and Stop-limit feature on wheelbarrows for automatic load adjustment

Abstract

A swivel adaptation to wheelbarrows is presented for patent that allows the tray assembly to adjust to rolling terrain—independent of ground levelness. The swivel is combined with a limiting feature that prevents the tray from overturning under conditions of load shifting. This invention is of particular value when incorporated into wide wheel-based configurations such as those using multiple wheels.
