FRAME
The entire frame consists of multiple rails running parallel to each other with cross members forming a ladder
style frame.
The main frame rails are formed in the shape of a C-channel. Each rail is constructed of 50,000 psi minimum
yield high strength low alloy steel. A frame notch for the ramp installation is made on the curb side of the main
rail, eliminating the upper flange in this area. The notch is reinforced with a formed “Z” shaped frame
constructed of 50,000 psi minimum yield high strength low alloy steel.
Mid-section frame rails are a transition frame rail constructed of 100,000 psi minimum yield high strength low
alloy steel. .
Rear frame rails are formed in the shape of a C-channel. Each rail is constructed of 50,000 psi minimum yield
high strength low alloy steel.**Should weight savers be required to accommodate the CNG system, we ask for
approval of optional Azdel Composite in place of luaun in the exterior and interior walls which adds an R-value
of 2 to the vehicle (for a total R-Value of 9) and approval of exterior FRP skin in place of our standard
galvanized skin**
A minimum of two (2) structural ¼” thick grade 50 cross members are installed in the main chassis. All other
cross member and outriggers are formed out of 7 GA grade 50. All cross members and outriggers are spaced
approximately 24” on center. Each frame joint has a reinforcement plate overlapping the splice.
The material was prepped in a wash process with calcium phosphate during a surface cleaning technique
applied prior to the powder coat finish before installation.
FLOOR
The floor structure is covered with 5/8” marine tech 7-ply plywood. It is attached with a polyurethane adhesive
sealant and mechanically fastened into the cross members.
The floor structure is sealed to keep outside elements from entering the vehicle with an expandable,
polyurethane spray foam.
