A dual wheel foldable hand truck with a nose plate has a skeletal frame including laterally spaced vertical side rails. The frame has hingedly connected upper and lower frame sections with upper and lower side rails meeting at side rail interfaces. Handle operated lock slides are carried by the upper rail sections for downward sliding movement to releasably lock the frame sections in planar alignment. The foldable nose automatically locks in operative position when swung down from stowed position.
