ABSTRACT:
Road tanker for an articulated vehicle, for hauling petroleum or other liquid products. The tanker has an elongated vessel provided internally with dividers. The dividers are joined to the side walls of the vessel by "U-shaped" extrusions providing dual connection between the dividers and the wall. The forward end of the vessel is provided with a skid plate which is integral with or located so as to be substantially at the same level as the bottom surfaces of the vessel. The forward and rearward vertical corners are hollow sections to reinforce the vessel at those locations. The vertical sides of the vessel are joined to the top panel by means of rails which inhibit rolling of the tanker from the side panels to the top panel.
