APPLICATIONS OF SUPERSTRUCTURES
3.4 CONTAINER APPLICATION
– Printed 603.95.994 – 1 Ed. - Base 05/2015
The mounting of dump bodies and structures having high torsional rigidity in general requires the use of flexible couplings towards
the front part of the structure to avoid excessive reduction of the deformation characteristics of the main chassis.
Vans integrated with the cab
The coupling in these cases must be implemented so as to limit the stress transmitted to the vehicle cab.
For couplings and fitting reinforcements, bear in mind that:
● no welding should be performed on the sheet metal of the cab and only mechanical fixture systems should be used;
● the self-supporting structure of the van must not require additional support provided by the cab;
● the parts of the cab affected by the conversion must be protected against oxidation and corrosion (see Chapter 2.2
( ➠ Page 7)).
Tipper bodies
The use of tipper bodies, rear and three sided, generally subjects the chassis to considerable stress.
Therefore, please observe the following indications.
1. The use of a stabiliser bar on all IVECO models for which it is an optional, is recommended.
2. The counter chassis must be:
■ suitable for the type of vehicle and conditions of use,
■ with appropriately sized cross members and side members,
■ with the rear end stiffened with boxing and crossbraces (see Figure 6 and Figure 7). The connections to the chassis must
be flexible (brackets or supports) at the front end, whereas the rear section requires stiff connections (cleat plates) (see
Figure 11) to allow the added structure to contribute more to the stiffness of the assembly. Omega shelves can be used
on vehicles on where these are originally fitted.
3. The rear tipping hinge must be fitted on the counter chassis; its position must be as near as possible to the rear support of the
rear suspension. In order not to affect the vehicle's stability during tipping and not to excessively increase the stress on the
chassis, the distance indicated in Figure 15 must be respected. Should this not be possible, the counter chassis profiles must be
larger than normal and additional reinforcement must be applied to the rear.
4. Great care must be given to the positioning of the lifting device both in terms of providing support of adequate strength and
in order to correctly position the mountings. In any case, it is advisable to place the ram to the front of the centre of gravity of
the body and payload so as to reduce the extent of the localized load.
5. In rear tipping it is recommended that a stabiliser is fitted to guide the container, particularly when the lifting cylinder is located
behind the cab.
6. The lifting device hinge must be mounted on the counter chassis. The useful volume in the body must conform with the max-
imum permissible load on the axles, to the density of the material to be transported (a density mass of approximately 1600
kg/m
3
is to be used for excavated material). In the case of transporting freight with a low density, the useful volume may be
increased within the limits established for the maximum height of the centre of gravity of the payload (plus the fixtures).
7. The Body builder must ensure the functioning and safety of all parts of the vehicle (e.g. the positioning of lights, towing hook
etc.) and ensure that, following the addition of the structure, vehicle stability is guaranteed during tipping operations.
