2019 International MV/PL Custom Titan 170 <br />Type I Ambulance Proposal Specification <br />TYPE I MEDIUM DUTY AMBULANCE SPECIFICATIONS <br />VEHICLE DIMENSIONS: <br />296" Long <br />99" Wide <br />111" High <br />72" Headroom <br />EXTERIOR MODULAR BODY <br />EXTERIOR, ALUMINUM BODY CONSTRUCTION <br />FRAMES: <br />The module body shall consist of an electric welded, unitized aluminum roll cage structure throughout. The framework <br />shall consist of six individual frames that are constructed in such a manner to insure squareness and flatness before being <br />assembled into a box configuration. <br />MATERIAL: <br />All material used on any frame member, corner and upper cove shall be high strength aluminum alloy. This alloy shall be <br />6061 J6 with tensile strength of 45,000 psi. The use of lesser materials such as 6063 is not allowed due to its lesser <br />mechanical properties. The ultimate strength of 6061-T6 is approximately 25% greater than 6063 alloy. Material <br />-ertifications showing 6061 J6 alloy shall be provided upon request to verify the use of this material for all frame <br />J�bmbers. <br />WELDING: <br />All welding done on any part of the frame structure shall be done by welders tested in welding this alloy and type of <br />structure, Welders testing certifications shall be provided upon request. All butt welds shall have 100% weld penetration <br />using a filler wire approved for this alloy aluminum. All welding shall be done in accordance with American Welding <br />Society (AWS), Structural Welding Code. <br />FLOOR FRAME: <br />The main floor structure shall consist of a primary load bearing support frame. This primary frame shall consist of <br />2`x3"x.250" square wall tubular aluminum. This primary frame is of critical importance to the structural integrity of the <br />module. The use of channel sections or frame members less than 2" x 3" x.125" is not acceptable due to its moment of <br />inertia and section modulus calculations are less than minimum acceptable. The secondary support frames of the floor <br />frames shall consist of 2"x 2" x.250" (square) and 1 1/2" x 2" x.125" (rectangular) wall tubular aluminum. Areas between <br />exterior compartments and sub -floor support members shall be a minimum of 2"x 2" x.250 (square). <br />A heat shield made of 22 GA galvanized steel is attached to the underside of the Floor Frame. The shield is creased for <br />stiffness and deflects the heat of the exhaust from the modular body. The heat shield is required for compliance with Ford <br />QVM and good practice design. <br />A4539-0001 <br />08/24118 <br />
