American Response Vehicles <br />11 <br />three-sided extruded channel with two sides being .125-inch-thick and the bottom surface for fastener <br />acceptance to be .160-inch will be full length of the body. <br /> <br />ROOF CORNERS: The roof rail extrusions will be welded together along the roof bow mating walls at the <br />corners. In addition, the outer surfaces of the roof rail extrusions will be 100% continuously TIG welded <br />to cast aluminum corner castings. The castings will have internal mating flanges that extend <br />horizontally inside the upper roof rail extrusion and vertically down the corner post extrusions. The <br />corner roof castings will have accommodations for number six nylon inserts to retain corner cap marker <br />combination warning lights when they are specified. The nylon inserts will provide isolation of the <br />retaining screw of the light from the casting materials. <br /> <br />FLOOR MEMBERS: Floor structures will be 6105-T6 aluminum, 2.000 by 2.500-inch proprietary hollow <br />section architectural box tubing aluminum. This proprietary shape tubing allows for half-inch plate to <br />be recess to which floor mounted items can be securely connected. Each member will have a defined <br />bevel built into the extrusion die to allow for full weld penetration on the edge of the extrusions. <br /> <br />FLOOR HORIZONTAL GUSSET PLATES: The floor member to side wall fully welded horizontal gusset <br />system will be made of 5052-H32 aluminum plate, four (4) by four (4) inch triangles. A minimum of 12 <br />gussets will be located horizontally connecting cross members to longitudinal main center members at <br />each main cross member site. <br /> <br />FULL WIDTH CROSS MEMBERS: The module floor will provide core support for the side assemblies and <br />will incorporate a minimum of four (4) full body width floor members. The full width floor members <br />will connect to and support the side wall assemblies. Each member will be made of 6105-T6 aluminum. <br />The front floor tube is to be a minimum of 3.000 x 2.000 x .250 inch-thick 6105-T6 aluminum tube <br />which is fully MIG welded into the front corner post at each side of the vehicle. On top of the tube is to <br />be a minimum .188 thick 5052 aluminum front sill running full width of the body. One of the members <br />located just forward and/or rear of the rear wheel housing will be 2.000 by 2.500-inch proprietary <br />hollow section architectural box tubing. The last floor cross-member will be a 2.375 x <br />3.188 6105-T6 aluminum proprietary shape proof tube on the rear wall which is fully MIG welded into <br />the rear corner posts at each side of the vehicle. This tube is butted up and welded to a 2.000 x 1.000 x <br />.125 inch-thick 6105-T6 tube which is also fully MIG welded to the rear corner post. A minimum of <br />eight (8) total 6-inch vertical gussets, (1/4) inch thick will be installed to reinforce two (2) at each cross <br />member and sidewall tubes directly fore and aft of the axle. <br /> <br />FLOOR SYSTEM CANTILEVER BEAMS: There will be cantilever floor beams used at intermittent body <br />points running from the opposite main interior wall beam to the opposite exterior wall at the location <br />between exterior compartments. The use of cantilever beams increases the strength of the overall <br />floor system and support to the compartments. <br /> <br />WHEELWELLS: There will be formed wheel well housings installed into the module body to provide sufficient <br />clearance for the rear axle movement based on the chassis jounce study and suspension choice selected.
