CAB STYLE
The cab shall be a custom, enclosed model, built specifically for use as an emergency response vehicle by a company
specializing in cab and chassis design for all emergency response applications.
The cab shall be manufactured for heavy-duty service utilizing superior strength and capacity for the application of
protecting the occupants of the vehicle. The cab shall be of a modular design offering improved strength, durability and
reduced weight. The modular design shall allow for faster, less costly replacement of components. Per pound, 6061-T6
aluminum extrusions offer a higher tensile strength, 45,000 PSI, and yield strength, 40,000 PSI, than that of lower grade
sheet such as 3003-H13. For this reason, the cab shall be of aluminum extrusion construction, which shall offer superior
strength and the truest, flattest surface ensuring less expensive paint repairs if needed.
The method of cab construction shall use a process incorporating techniques outlined in accordance with the American
Welding Society D1.1-96 requirements for structural steel welding. All aluminum welding shall be completed to the
American Welding Society and ANSI D1.2-96 requirements for structural welding of aluminum.
To provide a superior finish by reducing welds that fatigue cab metal; the roof, the rear wall and side panels shall be
assembled using proven industrial adhesives, designed specifically for aluminum fabrication, which exceed the strength of
a weld, for construction.
All interior and exterior seams shall be sealed for optimum noise reduction in addition to the most favorable efficiency for
heating and cooling retention.
The cab shall be constructed of 5052-H32 corrosion resistant aluminum plate. The cab shall incorporate tongue and
groove fitted 6061-T6 0.13 & 0.19 inch thick aluminum extrusions for extreme duty situations. A single formed, one (1)
piece extrusion shall be used for the “A” pillar, adding strength and rigidity to the cab as well as additional roll-over
protection. The cab side walls and lower roof skin shall be 0.13 inch thick; the rear wall and raised roof skins shall be 0.09
inch thick; the front cab structure shall be 0.19 inch thick.
Proposals offering products built with anything less than the alloy-temper mentioned or from any material other than
aluminum, shall not be considered.
The cab shall incorporate a fully enclosed design, allowing for a spacious cab area with no partition between the front and
rear sections of the cab. The walls of the vehicle shall include roof supports allowing for an open design. The exterior
width of the cab shall be 94.00 inches wide with a minimum interior width of 88.00 inches.
The overall cab length shall be 128.00 inches with 54.00 inches from the centerline of the front of the axle to the back of
the cab. The cab shall offer an interior height of 58.00 inches from the front floor to the headliner and a rear floor to
headliner height of 65.00 inches in the crew area, at a minimum. The cab shall offer an interior measurement from the
rear of the engine tunnel to the rear wall of the cab of 52.00 inches. All interior measurements shall include the area within
the interior trimmed surfaces and not to any unfinished surface.
In order to offer the optimum amount of cab space to occupants, there shall be no consideration given for any cab unable
to comply with the minimum measurements for interior cab space as listed.
The cab shall include a driver and officer area with two (2) cab doors. The front doors shall offer a clear opening of
40.00 inches wide X 53.50 inches high. The cab shall also include a crew area with up to two (2) cab doors. The rear
doors shall offer a clear opening of 31.00 inches wide X 61.00 inches high. This style of cab shall offer up to eight (8)
seating positions.
