  • Patent number: 5301980
    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.

    Abstract: A mobile road or rail tanker. The tanker is formed of sheet aluminum which forms an outer shell. The shell encloses a chamber which is divided by a transverse wall. The wall adjacent the shell comprises an annealed heat treatable weldable aluminum alloy which is relatively soft and ductile so that weld material adjacent the wall is stronger than the remainder of the wall.
