Self-supporting superstructures with counter chassis functions
The interposition of a counter chassis (longitudinal and transverse) can be omitted in the case of installation of self-supporting su-
perstructures (e.g. vans, tanks), or when the underlying structure of the equipment to be installed already has the counter chassis
conformation.
3.3
CONNECTION BETWEEN CHASSIS AND COUNTER CHASSIS
Choosing the type of connection
The choice of the type of connection to be used, if not provided by IVECO originally, is very important for the purposes of contri-
bution of the counter chassis in terms of strength and stiffness.
It can be elastic (brackets or clamps) or rigid, resistant to shear stress (plates sealed longitudinally and transversally); the choice must
be made
according to the type of superstructure to be applied (see Chapters 3.4 to 3.14), evaluating the stresses that the added
equipment transmits to the chassis, both in static and dynamic conditions. Number, size and construction of the anchors, reasonably
allocated in the length of the counter chassis, must be such as to ensure a good connection between the chassis and the counter
chassis.
The screws and the clamps must have material strength class of not less than 8.8, and the nuts must be fitted with systems that
prevent unscrewing. The first anchor should be positioned, if possible, at a distance of about 250÷350 mm from the front end of
the counter chassis.
The elements for the original connection already existing on the vehicle chassis must be preferred.
The respect of the distance indicated above for the first anchoring must be ensured especially in the presence of superstructures
with concentrated loads behind the cab (e.g. crane, front body tilting cylinder, etc..), in order to improve the magnitude of the
chassis stresses and contribute more to the stability. Provide additional connections if necessary.
If you have to install a superstructure with features different from those for which the chassis was designed (e.g. a tipping body on a
chassis built for a fixed body) suitable connections must be provided (e.g. replacement of brackets with shear resistant plates in the
rear area of the chassis).
▶
In anchoring the structure to the chassis, welding must not be performed on the vehicle chassis,
nor may holes be put into its wings.
In order to improve the longitudinal and transverse containment of the connection, drilling is permitted on the wings of the side
members but only at the rear end of the side members, in a section which is no longer than 150 mm and without weakening the
anchoring of any cross members (see Figure 12).
