Abstract: A hand truck or trolley comprises a frame having an upper side and an underside, a rear axle connected to the frame proximately to a rear edge thereof, a pair of rear wheels attached to the rear axle for rotation about an axis defined by the axle, and a handle pivotably coupled to the axle and thus to the frame for rotation about the axis. A cross-brace is pivotably connected to the handle for rotation about an axis spaced from the axle, while coupling elements are provided on the cross-brace and the frame for releasably connecting the cross-brace to the frame at a point spaced from the axle and from the coupling between the handle and the cross-brace. The cross-brace establishes a triangulated truss connecting the handle to the frame in a use position of the handle.
