The rear vertical corners of the apparatus body shall be recessed to provide a mounting area for
telescoping light poles.
COMPARTMENT ROOF CONSTRUCTION
Each compartment top shall have a bolt in 12-gauge stainless roof section for supporting roof loads
of up to 500 pounds per square foot without permanent roof deformation.
REAR FRAME EXTENSION
The rear chassis frame extension system shall consist of a interwoven dual .625" thick steel drop
frame extensions with a transverse 4" x 3" x .375" thick structural channel, and dual laminated
.188" thick rear compartment and tailboard support tapered angles on each side of apparatus. The
extension shall be bolted to the chassis frame utilizing Grade 8 bolts and Grade C locknuts with
hardened washers. For ease in replacement of damaged components in an accident there shall be
no welding of components to the chassis frame. Two (2) tow eyes with an eye diameter of not less
than 3.5" shall be attached directly to the chassis frame extensions. The tow eyes shall be
fabricated of .625" thick steel.
BODY MOUNTING SYSTEM
The right and left side compartments shall be attached to a stainless steel body support. The
stainless steel support shall be attached to the chassis frame extensions by means of an elastomer
spring mounting system to form a modular integral body support system. The design shall allow
for maximum chassis flexing without undue stress transfer to the apparatus body.
The apparatus body shall not rest upon the chassis truck rails and must be separated entirely from
the steel frame of the chassis to prevent galvanic action. Loose fitting u-bolt body mounting
systems are not acceptable due to the likeliness of the apparatus body shifting or becoming
detached from the chassis upon rear end impact.
COMPARTMENT INTERIOR FINISH
For better interior visibility, to reflect light better, ease of maintenance and prevent the masking of
poor welds and questionable workmanship the interior of the body compartments shall remain
uncoated.
EXTERIOR ROOF FINISH
The top of the compartments shall be brushed stainless steel.
REAR TAILBOARD
A rear tailboard 10" deep shall be provided at the rear from "Laser Grip" stainless steel meeting
NFPA 1901 step requirements. The tailboard shall provide protection for the side body
compartments and shall provided recessed mounting for the rear ICC marker lights. It shall be
bolted to the rear support structure.
COMPARTMENT DESIGN AND CONSTRUCTION
All compartments shall be manufactured from 12-gauge stainless steel with the vertical front and
rear corner walls from 14-gauge, they shall be of sweep out design and shall be bolted together.
Stainless recessed round head bolts and stainless aircraft style "ESNA" nuts shall be applied for
each fastener.
Wherever possible, body bolts shall be hidden from plain view for appearance and ease of
apparatus cleaning.
