Abstract: Road transport vehicle for securing and transporting large plates of glass. The road transport vehicle transports the plates, such as glass, in a large load space located between the rear axles of the vehicle. The road transport vehicle supports the plates such that they are inclined against a pair of interior brace walls and supported from beneath by a frame. The plates are secured with a pair of transport braces which are hydraulically actuated through a parallel crank gear which maintains the transport braces in a parallel relation to the plates throughout the full range of the transport braces, regardless of the aggregate thickness of the plates. The securing force imparted by the transport braces is in a generally downward direction and toward the inclined plane of the plates so as to accommodate various sizes and thicknesses of plates. A buffer is employed to avoid damage to the plates by better distributing the securing force.
