APPLICATIONS OF SUPERSTRUCTURES
3.7 INSTALLATION OF TANKS AND LOOSE MATERIAL CONTAINERS
– Printed 603.95.994 – 1 Ed. - Base 05/2015
Note
For the dimensions of the profiles see Table 3.2.
The assembly of tanks, or stiff torsional structures in general, must ensure sufficient and gradual flexibility of the chassis, in order to
avoid high stress areas.
The use of flexible parts is recommended for the connections between the cistern body and the counter chassis (see Figure 16) in
the front part and rigid supports resistant to the longitudinal and transverse forces towards the rear part.

Figure 16
As previously mentioned, the stiff connections positioned in correspondence with the rear suspension mounts are more suitable
for transmitting forces directly to the suspension elements; elastic connections are to be arranged near the front suspension rear
mount.
If this is not carried out, use suitably oversized longitudinal reinforcement sections with respect to those shown in Table 3.6.
When defining elastic connections, consider the rigidity of the chassis in the area where the connections are to be applied and the
type of functions for which the vehicle is intended.
b) Installation without a counter chassis
The application of tanks directly on the chassis is possible under the following conditions:
● the distance between the various rests must be established according to the load to be transmitted (approximately no more
than 800 m);
● the rests must be realized so as to distribute the load uniformly over a suitably wide surface and with appropriate cross bra-
cings (see Figure 16) to contain the longitudinal and transverse pressures;
● the anchoring points must be of sufficient length (approx. 400 mm – see Figure 17) and be positioned in the immediate vicin-
ity of the suspension connections.
Specifically, the front anchoring flexibility must be suited to contain the necessary torsional movements of the chassis;
● other anchoring solutions must be authorised by IVECO.
