ROOF CONSTRUCTION
The roof shall be integral with the body and shall be all welded construction. The roof of the body shall not be less
than 3/16" aluminum 3003H-14 alloy tread plate, fully and continuously welded. The roof shall be reinforced with
2" x 2" x 1/4" aluminum tubing running the full width of the body.
All seams in the roof area shall be welded to the radius and supports prior to paint to prevent entry of moisture. All
roof seams shall be continuously welded.
A 2" formed radius shall be provided along the body sides. The use of extruded radius will not be acceptable, No
Exceptions.
BODY SUBFRAME
The chassis frame rails shall be fitted with 1/4" custom extruded UHMW polyethylene rail cap to isolate the body
frame members from direct contact with chassis frame rails.
The body subframe shall be constructed from 6061T6 aluminum alloy tubing. Subframe shall consist of two (2) 2"
x 6" x 1/4" aluminum tubes, the same width as the chassis frame rails, NO EXCEPTION. Welded to this tubing
shall be cross members of 2" x 6" x 1/4" aluminum. These cross members shall extend the full width of the body
to support the compartments. Cross members shall be located at front and rear of the body, below compartment
divider walls, and in front and rear of wheel well opening. Additional aluminum cross members shall be located on
16" centers, or as necessary to support walkway or heavy equipment.
To form the frame, the tubing shall be beveled and welded at each joint using 5356 aluminum alloy welding wire.
BODY MOUNTING
The body subframe shall be fastened to the chassis frame with a minimum of six (6) spring loaded body mounts.
Each mount shall be configured using a two-piece encapsulated slide bracket. The two (2) brackets shall be
fabricated of heavy duty 1/4" thick steel and shall have a powder coat finish to prevent any corrosion. Each
mounting assembly shall utilizing two (2) 3/4" diameter x 6" long grade 8 bolts and two (2) heavy duty springs.
The assembly design shall allow the body and subframe to act as one (1) component, separate from the chassis.
As the chassis frame twists under driving conditions, the spring mounting system shall eliminate any stress from
being transferred into the body. The spring loaded body mounts shall also prevent frame side rail or body damage
caused by unevenly distributed stress and strains due to load and chassis movement.
Body mountings that do not allow relief from chassis movement will not be acceptable.
10" REAR STEP BUMPER
The full width rear bumper shall be constructed from 2" x 2" x 1/4" aluminum tubing frame and covered with 3/16"
NFPA compliant aluminum tread plate. The bumper shall extend from the rear vertical body panel 10" and provide
a rear step with a minimum of 1/2" space at body for water drainage.
REAR TOW EYES
There shall be two (2) heavy duty rear mounted tow eyes securely attached to the body subframe, below the
apparatus body. The tow eyes shall be fabricated from 3/4" thick steel plate and shall have a black powder coat
finish.
