ABSTRACT:
The invention is a wheelbarrow which includes a hand-actuated braking system. The wheelbarrow comprises a frame, a wheel rotatably attached to the frame, a pan attached to the frame which contains the material to be transported, and a braking system which allows the user to manually apply a braking force to the wheel. The braking system employs a drum brake consisting of one or more brake shoes disposed within the hub of the wheel. A backplate encloses the brake mechanism within the hub to hinder foreign matter, such as water, mud, or oil from interposing itself between the brake shoe or shoes and the inner surface of the hub and interfering with the generation of the braking force. The braking system is actuated by means of a pivoted lever installed on the frame and linked to the brake by a flexible cable whose length can be adjusted. Legs can be attached to the bottom of the frame so that the wheelbarrow can stand unsupported in an upright position.
