REV: 04-29-25 LF <br />TRACTOR/TILLER COMMUNICATIONS SYSTEM <br />A system shall be installed to provide two-way communications between the tractor cab and the <br />tiller cab as described elsewhere within these specifications. <br />MUD FLAPS <br />Heavy-duty black rubber mud flaps shall be provided behind the rear wheels of the chassis and <br />behind the tiller axle. The mud flaps shall be bolted in place. <br />WHEEL COVERS <br />There shall be chrome plated lug nut covers and hub caps installed on the tiller wheels. <br />FORMED ALUMINUM BODY <br />The apparatus body shall be a formed aluminum design, which serves as the structural skeleton <br />to support the body and its contents. The entire formed structure shall be welded together utilizing <br />an A.W.S. Certified welding procedure. <br />BODY STRUCTURE MEMBERS <br />The body shall have structural members in certain areas of the body. The body shall be designed <br />for maximum strength to weight ratio, therefore the gauge of sheet metal and structural members <br />varies from .125 inches (3.18 mm) to .250 inches (6.35 mm) throughout, dependent on the design <br />requirement. <br />BODY MATERIAL TYPE <br />All body structural members shall be Aluminum 6061-T6 alloy material. All .125 inch (3.18 mm) <br />sheet material and .188 inch (4.78 mm) sheet materials shall be Aluminum Alloy 5052-H32. These <br />alloys are required because it provides optimum all-around performance for strength, <br />manufacturing properties, and corrosion resistance. <br />ECK® ANTI-CORROSION PROCESS <br />Absolutely no dissimilar metals shall be used in the body and its supporting substructure without <br />being separated by Eck®, which prevents corrosion by providing a barrier between dissimilar <br />metals, sealing out moisture and absorbing energy created by a dissimilar metal reaction. <br />FRONT BODY COMPARTMENT WALLS <br />The front compartment walls of both forward most compartments shall be sheet finished. No <br />overlay material shall be visible from the interior of the compartments. <br />REAR BODY COMPARTMENT WALLS <br />The rear compartment walls of both rearward most compartments shall be sheet finished. No <br />overlay material shall be visible from the interior of the compartments. Access panels from the <br />rear walls shall be strategically placed to ensure access to the rear taillight clusters for any <br />servicing that may be completed. <br />ATTY/AGR.2025.089/Fire Apparatus Solutions (Purchase of Spartan-LTC 105' TDA) (Page 86 of 150)
