2021 International MV/PL Custom Titan 170 <br />Type I Ambulance Proposal Specification <br /> <br /> <br />A5347-0002 11/05/20 <br />3 <br /> <br />custom aluminum extrusions in place of box beam members as required. The door openings shall be exactly as specified <br />for the doors located on the vertical side frames as described previously. <br /> <br />ROOF FRAME: <br /> <br />The roof frame of the vehicle shall be fabricated from 2 inch by 1 1/2 inch by .125 inch box beam structural members. The <br />transverse frame members shall be spaced a maximum of 12 inches on center. <br /> <br />MODULE ASSEMBLY: <br /> <br />The six frames as previously stated shall be assembled into a module, including the floor, front, rear, two sides and roof <br />sub frame before any of the exterior skin is applied. The structural frame work shall be a self-supporting body and not <br />require the use of the exterior skin for structural integrity. The framed body, without the skin shall be capable of supporting <br />the required static load of the vehicle per A.M.D. 001 specifications. <br /> <br />The floor frame shall be welded to the two vertical side frames at the area of the floor, in front and behind t he wheel box <br />area. This welding shall be 100% continuous in these areas. <br /> <br />The full perimeter welding and center bonding of the exterior panels shall enhance the overall strength of the modular <br />body. <br /> <br /> <br />SIDE IMPACT PROTECTION <br /> <br />BODY PROTECTION <br /> <br />Per Federal Motor Vehicle Safety standards, the vehicle shall be designed to protect the occupants or equipment from <br />side impacts. This shall be accomplished by: (a) Two side impact rails with minimum dimensions of, 2 inch by 5 inch by <br />.125 inch 6061-T6 aluminum alloy, structural box beam member located approximately 24 inches from the lower side rail; <br />and approximately 18 inches from the upper side (b) full structural members which extend across the body in the <br />transverse direction between the compartments. Modular bodies that do not provide this protection at each compartment <br />location shall be cause for rejection of the vehicle. <br /> <br />MODULAR BODY DOOR PROTECTION <br /> <br />In addition to the vertical body sides, each door with a vertical height greater than 30 inche s, on the left and right sides of <br />the vehicle shall incorporate a 2 inch by 5 inch by .125 inch 6061 -T6 aluminum alloy, structural box beam members. Each <br />member shall be welded to the interior door extrusions. The structural members shall be placed approx imately 24 inches <br />from the lower side rail. There shall be no exceptions to side impact protection in modular body doors. <br /> <br />EXTERIOR PANELS: <br /> <br />The two sides, front and rear shall be covered with .125" thick 5052-H34 stretcher leveled aluminum alloy sheet with <br />tensile strength of 38,000 psi. The center areas of the sheets shall be applied using "Very High Bond" structural bonding <br />tape. Before any tape is applied to the structure, both the sheets and the structure shall be thoroughly cleaned with an <br />approved solvent. In addition to the structural bonding tape the exterior skin shall be welded along the perimeter corners <br />and along all door openings. This welding is only done in areas that will not show dimple on the finished body module. <br />The side panels of the vehicle shall be single piece and not welded or fabricated. <br />
