Specifieations <br />The bacl:bone of the support system shall be the chassis franle rails which is the stronQest <br />component of the chassis and is designed for sustaining maximum laads. ? <br />The support system shall include .375" thick steel vertical anale supports bolted to the chassis <br />frame rails with .625" diameter bolts. V <br />Attached to the bottom of the steel vertical angles shall be horizontal anales, with gussets <br />welded to the vertical members, which extend to the outside edge of the body. <br />A steel frame sha11 be mounted on the top of these supports to create a"floating substrueture" <br />which shall result in a 500 pound equipment support rating per lower compartment. <br />The floatizlg substructure shall be separated from the horizontal members with neoprene <br />elastomer isolators. These isolators shall reduce the natural flex stress of the chassis from <br />being transmitted to the body. <br />Isolators shall have a broad load ranQe, proven viability in vehicular applications; be of a fail <br />safe design and allow for all necessary inovement in three (3) transitional and i-otational <br />modes. <br />The neoprene isoiators sha11 be installed in a modified "V" three (3)-point mountinc, pattern to <br />reduce the natural flex of the chassis being transmitted to the body. <br />A desigl with body compartments hanging on the chassis in an unsupported fashion shall not <br />be acceptable. <br />AGGRESSIVE '"'ALKING SURFACE <br />All exterior surfaces designated as stepping, standing, and wallting areas shall comply with <br />the required average slip resistance of NFPA section 13-7.3. <br />LOUVERS <br />AIl body compartments shall have a minimum of one (1) set of louvers stamped into a wall to <br />provide the proper airflow inside the compartment and to prevent water from dripping into the <br />compartment. These louvers shall be fornZed into the metai and not added to the comparnnent <br />as a separate plate. <br />TESTING OF BODY DESIGN <br />Body structural analysis shall be fully tested. Proven engineerinc; and test techniques such as <br />finite element analysis, stress coating and strain gauging have been periornzed Nvith special <br />attention given to fatigue, life and structural integrity of the cab, body and substructure. <br />Body shall be tested while loaded to its greatest inservice weight. <br />The criteria used during the testing procedure shall include: <br />Bidder <br />Complies <br />Yes I No <br />Page 38
