Specifications

Smeal Pumper Demo # 4276
Page 36 of 58
Ultra Stainless™ steel fasteners shall be provided for all exposed and unpainted fasteners throughout the
body in locations such as overlays, pump panels, and other numerous hardware mounting locations. The
special ingredient in Ultra Stainless™ is Marutex®, which adds 2% molybdenum (moly) to 410 stainless.
Moly is the significant component of 316 stainless that provides extra corrosion resistance. The moly is
now added to 410 self drilling screws to produce Ultra Stainless™. This combination provides for
unprecedented corrosion resistance combined with hardness for drilling.

ADDITIONAL HARDWARE
There shall be a bag of stainless steel nuts, bolts, and washers supplied with the apparatus for mounting
of equipment.

GS-36 BODY SUB FRAME
To assure proper body alignment and clearance, the body sub frame shall be constructed in a jig and
fitted directly on the chassis.

The chassis frame rails shall be fitted with fiber reinforced rubber to isolate the body frame members from
direct contact with chassis frame rails.

The main body sub frame shall be constructed from steel tubing. The sub frame shall run the full length of
the body and shall be spaced the same width as the chassis frame rails. The main sub frame shall also
be the integral support for the water tank. Vertical drop tubes shall be welded to the sub frame. From
these vertical drop tubes shall extend cross members constructed of steel angle. These cross members
shall extend out to support the compartments. Cross members shall be located at the front and rear of the
body and in front and rear of the wheel well opening.

The compartment area behind the rear axle shall be supported by a drop frame fabricated of steel tube
and steel angles. The rear drop frame shall be constructed using vertical drop tubes, welded to the main
sub frame. All drop frame structures shall be welded directly to the body sub frame to allow the body to be
a completely separate structure from the chassis.

After fabrication the sub frame shall be hot dip galvanized for maximum protection against corrosion.
BODY MOUNTING
The body sub frame 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 bracket. The two (2) brackets shall be
fabricated of steel plates. The plates shall be painted to prevent any corrosion. Each mounting assembly
shall utilize two (2) plated bolts and two (2) heavy duty springs. The assembly design shall allow the body
and sub frame to act as one (1) component, separate from the chassis. As the chassis frame twists under
driving conditions, the spring mounting system shall limit 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 shall not be acceptable.
