US Classification:

280 4731, 280 473, 280 4724, 280 4732, 280 78, 280 63

Abstract:

A wheelbarrow has a main frame defining two laterally spaced-apart longitudinal portions, to which an axle is mounted with a wheel rotatably mounted thereto, and to which a body, such as a tub or flat bed, is mounted for carrying a load. Attached to the main frame are leg structures, each of which includes a straight base portion configured for aligning with and engaging the ground. Forward cross-braces are connected from a forward end of each base portion to a first point on the main frame, and rearward cross-braces are connected from a rearward end of each base portion to a second point on the main frame proximately adjacent to the first point. A lateral member extends from one longitudinal portion of the main frame to the other longitudinal portion, and a lateral cross brace extends from each leg structure to the lateral member.
