ABSTRACT:
A hand-operated, wheeled carrier for transporting large-sized plates, such as building boards, comprises a stand including a generally upright frame structure mounted on an elongate base structure having along one longitudinal side thereof brackets, on which a small number of plates to be carried may be rested on edge in a position leaning against the frame structure, a hook member and strap connected to the stand being provided to releasably retain the plates in such position. Substantially midway between its ends and close to the plate brackets the base structure has a single, relatively large supporting wheel adapted to take the entire load, when the stand is to be moved, the stand then being balanced on the single wheel by the operator. A pair of casters, one near each end of the base structure, provide additional supports for keeping the stand in a stable position when at rest, the casters being located further away from the plate brackets than the supporting wheel. The frame structure of the stand includes a substantially horizontal and easily accessible handle bar of considerable length.
