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 eight (8) 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.

opening.

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.
GROUND LIGHTS

minimum level of 2 fc (20 lx) on ground areas within 30 in. (800 mm) of the edge of the vehicle in areas designed for
personnel to climb onto or descend from the vehicle to the ground level.
