REV: 04-29-25 LF <br />inch aluminum wheels with bright machine finish. The hub piloted mounting system shall provide <br />easy installation and shall include two-piece flange nuts. <br />BALANCE WHEELS AND TIRES <br />All of the wheels and tires, including any spare wheels and tire assemblies, shall include <br />Counteract brand balancing beads. <br />WHEEL TRIM <br />The front wheels shall include stainless steel lug nut covers and stainless-steel baby moons <br />shipped loose with the chassis for installation by the apparatus builder. The baby moons shall <br />have cutouts for oil seal viewing when applicable. <br />The rear wheels shall include stainless steel lug nut covers and band mounted spring clip stainless <br />steel high hats shipped loose with the chassis for installation by the apparatus builder. <br />The lug nut covers, baby moons, and high hats shall be RealWheels® brand constructed of 304L <br />grade, non-corrosive stainless steel with a mirror finish. Each wheel trim component shall meet <br />D.O.T. certification. <br />BRAKE SYSTEM <br />A rapid build-up air brake system shall be provided. The air brakes shall include, at a minimum, <br />a two (2) air tank, three (3) reservoir system with a total of 4152 cubic inch of air capacity. A floor <br />mounted treadle valve shall be mounted inside the cab for graduated control of applying and <br />releasing the brakes. An inversion valve shall be installed to provide controlled service brake <br />application during the unlikely event of primary air supply loss. All air reservoirs provided on the <br />chassis shall be labeled for identification. <br />The rear axle spring brakes shall automatically apply in any situation when the air pressure falls <br />below 25 PSI and shall include a mechanical means for releasing the spring brakes when <br />necessary. An audible alarm shall designate when the system air pressure is below 60 PSI. <br />A four (4) sensor, four (4) modulator Anti-lock Braking System (ABS) shall be installed on the front <br />and rear axles in order to prevent the brakes from locking or skidding while braking during hard <br />stops or on icy or wet surfaces. This in turn shall allow the driver to maintain steering control <br />under heavy braking and in most instances, shorten the braking distance. The electronic <br />monitoring system shall incorporate diagonal circuitry which shall monitor wheel speed during <br />braking through a sensor and tone ring on each wheel. A dash mounted ABS lamp shall be <br />provided to notify the driver of a system malfunction. The ABS system shall automatically <br />disengage the auxiliary braking system device when required. The speedometer screen shall be <br />capable of reporting all active defaults using PID/SID and FMI standards. <br />Additional safety shall be accommodated through Automatic Traction Control (ATC) which shall <br />be installed on the single rear axle. The ATC system shall apply the ABS when the drive wheels <br />lose traction. The system shall scale the electronic engine throttle back to prevent wheel spin <br />while accelerating on ice or wet surfaces. <br />A momentary rocker style switch shall be provided and properly labeled “mud/snow”. When the <br />switch is pressed once, the system shall allow a momentary wheel slip to obtain traction under <br />ATTY/AGR.2025.089/Fire Apparatus Solutions (Purchase of Spartan-LTC 105' TDA) (Page 45 of 150)
