Specifications

Body component specifications – continued:
• Exterior body side walls shall be fiberglass reinforced and resin composite construction produced from
sandwiched plates with vacuum injection technology. Multiple laminates of glass fiber and resin
composite each having a minimum thickness of 3/16”. Woven and continuous glass fiber content of
composite material shall be a minimum of 40% with a maximum resin styrene content of 3%. Chopped
fiberglass fibers are not acceptable.
• Exterior front, rear and side body walls shall be a minimum of 1 ½” thick. Core material shall be a
closed-cell structure approximately 1 ½” thick with a minimum density of 12 ½ pounds per square foot.
Applied injection resins shall have a minimal HT rating of 185° Fahrenheit. Laminates shall have
flame-retardant characteristics.
• Body shall be completely resistant to ultra violet rays and operate in temperature ranges of -40° to
+175° Fahrenheit. The top of the body and tank shall be constructed of single laminate material with all
corners continuously sealed with resin and fiber for water tight construction.
• Entire body shall be non-conductive and shall be transparent to radio waves (EMI/RFI transmissions)
• Body and compartments shall be of a completely self-supporting design
• Points of chassis attachment on each side and full length of the modular body shall have fully integrated
reinforced assemblies of non-corrosive composite materials in a “u” shaped configuration. Two full
length reinforced 4” high body-substructure assemblies shall be integrated into the bottom of the body
system as a single assembly serving as the points of attachment to the chassis.
Body mounting system:
• Body and compartment module shall be mounted to the chassis with ten (10) mounting brackets, five
(5) each chassis frame bolted to the outside vertical frame rail.
• Mounting system shall provide total torsional isolation between the chassis frame and the body module
• Mounting system shall align the entire assembly longitudinally and transversely with the chassis frame
rails
• Body assembly with mounting members shall not rest directly on the upper chassis frame flange.
Frame mounting assemblies directly above and ahead of the rear axle shall be provided with springs for
an additional torsional movement.
• Body module mounting assembly shall consist of the following:
 7 gauge gusseted steel frame brackets attached with no less than four (4) grade 8, ½” diameter bolts
and locking nuts installed by final stage manufacturer
 Meta-cone high capacity hard rubber filled cone shaped shock-attenuating assemblies with piloted
flange washers bolted to frame brackets
 Each mounting shall have a vertical grade 8, 5/8” diameter bolt with piloted flange washers and pin
or locking nut securement. All mounting nuts shall be torque to the manufacturer’s requirements
Exterior compartment construction:
• Shall be integral with the body construction
• Compartments shall have painted 3” vertical exterior divider panels between each compartment and at
front and rear corners of body
• Compartment floor shall have a 4” horizontal structure for rub rail attachment of reinforced gusseted
composite construction
• Floor assembly shall be designed to provide a “lip free” sweep-out floor surface
