Connection with longitudinal and transverse sealing plates (rigid junction)
The type of mounting shown in Figure 11, made with plates that are welded or bolted to the counter chassis and fixed with nails or
screws to the vehicle chassis, ensures a good capacity for reacting to longitudinal and transverse thrusts and the greatest contribu-
tion to the stiffness of the assembly.

Figure 11
For the correct use of these plates, please keep in mind that:
●
the vertical rib of the chassis should be fastened only after making sure that the counter chassis is snug against the chassis itself;
●
the distribution must be limited to the central and rear area of the chassis;
●
the number and the thickness of the plates and the number of fixing screws must be adequate to withstand the bending mo-
ments and cutting of the section.
In cases where the superstructure generates high bending and twisting moments on the chassis and its resistant capacity should be
increased by adopting a cut-resistant connection between the chassis and the counter chassis, or if you want to contain the height
of the counter chassis as much as possible (e.g. centre axle trailers, crane on rear overhang, tail lifts, etc.), use the information sup-
plied in the table below (valid for all models):

(1)
The increase in the number of screws for each plate makes it possible to proportionally increase the distance between the plates (a
double number of screws may allow a greater distance between the plates). In high stress areas (e.g. the rear spring supports, the tandem
axle springs and the air springs), it is necessary to provide a distance between the plates, reduced as much as possible.
(2)
In the presence of contained thicknesses of the plates of the chassis and the counter chassis, it is advisable to connect by adopting spacer
bushes, in order to use longer screws.
(3)
For models 33S and 35S, the application of plates resistant to shear stress must be evaluated on an individual basis.
