South Bend Fire Department <br />CommanderChassis <br />One (1)AirSupply Lines Nylon <br />07-08-0570 <br />AIR SUPPLY LINES <br />A dual air system plumbed with color codedreinforced nylon tubing air lines shall be installed <br />on the chassis. The primary (rear)brake line shall be green, the secondary(front) brake line <br />orange, the parking brake line yellow and the auxiliary (outlet) will be black; in accordance with <br />SAE standards. No Exception. <br />Brass push-lock type fittings shall be used on thenylon tubing. All drop hoses shall include fiber <br />reinforced neoprenecovered hoses. <br />One (1)Frame Double Channel 35" FrameWidth <br />07-09-001B <br />FRAME <br />The chassis frame shall consist of two (2) “C” style parallelrails, constructed of high strength <br />low alloy and shall feature the following: <br />·A Stenx MODEL 110XF 10.19”high by3.63”deep coldrolledsteelframe orequivalent. <br />·.38” thick flange <br />·Inner channel measuring9.31" high x 3.25" deep x .25" thick <br />·The 10.19” frame heightshall be maintained throughout the entire length of the frame toallow <br />for maximum storage capacity for theentire apparatus. <br />·If frame rails that are larger than those specifiedare to be utilized, the maximum height of each <br />framerail shall not exceed 10.25” at any point on the frame rail. This will ensure the lowest <br />possible vehicle center of gravity allowing maximum stability as well as providing the lowest <br />body height possible. <br />·Framerail shall haveaconsistent frame web throughout the entire length. <br />·The entire framerail design shall be manufactured in the United States of America andreadily <br />available on the aftermarket. <br />·Grade 8 Structural fasteners, Huck bolts shall not be acceptable.No Exception. <br />·The hardware used for the chassis shall be are to be corrosion resistant. The process shall be dip- <br />spin-bake coated with two coats of zinc/aluminum metal flake coating in an inorganic binder. <br />Coating one is to be zincflake andcoating two is to be aluminum flake. The zinc flakes <br />sacrificially corrode to protect the base metal. Thealuminum flakes prolong the life of the zinc. <br />Salt fog test life, based on ASTM B117 on unassembled fasteners, is 1000hours to red rust. The <br />same test on assembled fasteners is 750 hours to red rust. The two step coating is RoHS <br />compliant as it eliminates the hexavalentchromium used in the passivation of electroplated zinc <br />coatings to create yellowzinc (zinc dichromate).The elimination of the zinc plating also greatly <br />reduces the likelihood that hydrogen embrittlement will occur. Hydrogenembrittlement is a side <br />effect of electroplating that reduces toughness andcan lead to fracture.
