AIR SUPPLY LINES
A dual air system plumbed with color coded reinforced nylon tubing air lines shall be installed on the chassis. The primary
(rear) brake line shall be green, the secondary (front) brake line red, the parking brake line orange and the auxiliary
(outlet) will be blue.
Brass compression type fittings shall be used on the nylon tubing. All drop hoses shall include fiber reinforced neoprene
covered hoses.
WHEELBASE
The chassis wheelbase shall be 180.00 inches.
REAR OVERHANG
The chassis rear overhang shall be 54.00 inches.
FRAME
The frame shall consist of single rails running parallel to each other with cross members forming a ladder style frame.
The frame rails shall be formed in the shape of a "C" channel, 10.25 inch web X 3.50 inches deep upper and lower
flanges X 0.38 inches thick. The high strength low alloy steel shall have a Tensile Elastic Limit of 110,000 psi. Each
single rail shall be rated by a Resistance Bending Moment (RBM) minimum of 1,830,400 inch pounds and have a
minimum section modulus of 16.64 cubic inches calculated by the radius method. The outside dimension frame shall
measure 34.25 inches in width.
Proposals calculating the frame strength using the “box method” shall not be considered.
Proposals including heat treated rails shall not be considered. Heat treating frame rails produces rails that are not uniform
in their mechanical properties throughout the length of the rail. Rails made of high strength, low alloy steel are already at
the required yield strength prior to forming the rail.
A minimum of seven (7) fully gusseted 0.25 inch thick cross members shall be installed. The inclusion of the body
mounting, or bumper mounting shall not be considered as a cross member. The cross members shall be attached using
zinc coated grade 8 fasteners. The head bolts shall be flanged type with distorted threads, held in place by flanged lock
nuts. Each cross member shall be mounted to the frame rails utilizing a minimum of 0.25 inch thick gusset reinforcement
plates at all corners balancing the area of force throughout the entire frame.
Any proposals not including additional reinforcement for each cross member shall not be considered.
Frame rails will be manufactured such that bolt attachment holes are specific for each component and shall not include
any unnecessary holes.
All relief areas shall be cut in with a minimum 2.00 inch radius at intersection points with the edges ground to a smooth
finish to prevent a stress concentration point.
The frame and cross members shall carry a lifetime warranty to the original purchaser. A copy of the frame warranty shall
be made available upon request.
Proposals offering warranties for frames not including cross members shall not be considered.
