TRUCK FRAME SECTION MODULUS
TABLES
Use Table E and Table F below along with Tables A through
D in the preceding section of this manual for determining the
section modulus of the truck frame.
Always measure the truck frame and check the tables to be
sure that any truck factory listed section modulus is correct. It
is also necessary to measure the frame and check the
section modulus wherever the depth and/or flange width
changes.
Channel (Table E). Table E supplements Table A for
narrower truck frame flanges. Use the width of the narrow
flanges for “W” to find the section modulus from Table E.
Angle (Table F). Use Table F for an angle section such as
when a flange and part of the web of a truck frame channel is
removed.
Where thickness, depth or flange width vary, interpolation
between tables or variables within a given table will provide
the strength for the section.
If you have any questions concerning frame strength or
reinforcing, contact National Crane before proceeding.
Where thickness, depth or flange width vary, interpolation
between tables or variables within a given table will provide
