A heated, automatic moisture ejector with a manual cable actuated drain provision shall be installed on <br />the wet tank of the air supply system. Manual cable actuated drain valves shall be installed on all <br />remaining reservoirs of the air supply system. The actuation pull cables shall be coiled and tied at each <br />drain valve. The supplied cables when extended shall be sufficient in length to allow each drain to be <br />activated from the side of the apparatus. <br />AIR SUPPLY LINES <br />The air system on the chassis shall be plumbed with color coded reinforced nylon tubing air lines. The <br />primary (rear) brake line shall be green, the secondary (front) brake line red, the parking brake line <br />orange and the auxiliary (outlet) will be blue. <br />Push to connect type fittings shall be used on the nylon tubing. All drop hoses shall include fiber <br />reinforced neoprene covered hoses. <br />AIR TANK SPACERS <br />There shall be spacers included with the air tank mounting. The spacers shall move the air tanks 1.50 <br />inches inward towards the center of the chassis. This shall provide clearance between the air tanks and <br />the frame for body U-bolt clearance. <br />REAR AIR TANK MOUNTING <br />If a combination of wheel base, air tank quantity, or other requirements necessitate the location of one or <br />more air tanks to be mounted rear of the fuel tank, these tank(s) will be mounted perpendicular to frame. <br />WHEELBASE <br />The chassis wheelbase shall be 223.00 inches. <br />REAR OVERHANG <br />The chassis rear overhang shall be 100.00 inches. <br />FRAME <br />The frame shall consist of double rails running parallel to each other with cross members forming a <br />ladder style frame. The frame rails shall be formed in the shape of a "C" channel, with the outer rail <br />measuring 10.25 inches high X 3.50 inches deep upper and lower flanges X 0.38 inches thick with an <br />inner channel of 9.44 inches high X 3.13 inches deep and 0.38 inches thick. Each rail shall be <br />constructed of 110,000 psi minimum yield high strength low alloy steel. Each double rail section shall <br />be rated by a Resistance Bending Moment (RBM) minimum of 3,213,100 inch pounds and have a <br />minimum section modulus of 29.21 cubic inches. The frame shall measure 35.00 inches in width. <br />Proposals calculating the frame strength using the "box method" shall not be considered. <br />Proposals including heat treated rails shall not be considered. Heat treating frame rails produces rails <br />that are not uniform in their mechanical properties throughout the length of the rail. Rails made of high <br />strength, low alloy steel are already at the required yield strength prior to forming the rail. <br />A minimum of seven (7) fully gusseted 0.25 inch thick cross members shall be installed. The inclusion <br />of the body mounting, or bumper mounting shall not be considered as a cross member. The cross <br />members shall be attached using zinc coated grade 8 fasteners. The bolt heads shall be flanged type, held <br />in place by distorted thread flanged lock nuts. Each cross member shall be mounted to the frame rails <br />
