CAB Bidder Complies: Yes ( ) No ( )
The cab shall be designed specifically for the fire service and shall be manufactured by the chassis
builder.
The cab shall be constructed of 5052-H32 aluminum skins on extruded aluminum framing. For
increased structural integrity and occupant protection, the cab structure shall include, directly forward
of the driver and passenger areas, a .25" firewall plate and .50" lateral support plate that shall tie the
forward corner posts to the engine tunnel. The cab roof shall include a heavy one-piece aluminum
extrusion with wall thickness up to .12", and shall extend from side to side, and attach to the upper
forward corner posts by customized aluminum castings. The sub-structure shall include a .38" wall
extrusion under the crew cab floor for support while tilting the cab. To provide quality at the source
and single source customer support, the cab shall be built by the apparatus manufacturer in a facility
located on the manufacturer's premises (no exception).
The cab shall be a full-tilt style to 80 degrees to accommodate engine maintenance and removal. The
cab pivots shall be located 46.00" apart to provide stability while tilting the cab. The cab shall be tilted
by an electric over hydraulic pump that is connected to two (2) cab lift cylinders 2.25" in
diameter. The cab shall be locked down by a two (2)-point automatic locking mechanism actuated
after the cab has been lowered. A three (3)-point cab mount system with rubber isolators shall
improve ride quality by isolating chassis vibrations from the cab.
The crew cab shall be a totally enclosed design with the interior area completely open to improve
visibility and verbal communication between the occupants.
The overall height (from the cab roof to the ground) shall be approximately 102.00". The overall
height listed shall be calculated based on a truck configuration with the lowest suspension weight
ratings, the smallest diameter tires for the suspension, no water weight, no loose equipment weight,
and no personnel weight. Larger tires, wheels, and suspension shall increase the overall height listed.
The cab shall have an interior width of not less than 93.50". The driver and passenger seating
positions shall have a minimum 24.00" clear width at knee level.
To reduce injuries to occupants in the seated positions, proper head clearance shall be provided. The
floor-to-ceiling height inside the forward cab shall be no less than 60.25". The floor-to-ceiling height
inside the crew cab shall be no less than 52.95" in the center position and 58.75" in the outboard
positions.
The crew cab shall measure a minimum of 57.50" from the rear wall to the backside of the engine
tunnel (knee level) for optimal occupant legroom.
CAB PUMP ENCLOSURE Bidder Complies: Yes ( ) No ( )
The rear of the cab shall be made to house the fire pump below the forward facing crew cab
seats. The cab side panels shall be notched to accommodate the pump panel.
