3.4.4 Tipping bodies
The use of rear or three-way tipping bodies generally subjects the chassis to considerable mechanical stress.
Therefore, the following indications must be observed.
1. The use of a stabiliser bar on all IVECO models for which it is an optional, is recommended.
2. The subframe 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 box sections and cross braces (see Figure 5 and Figure 6). The connections to the chassis
must be flexible (brackets) at the front end, while the rear section requires stiff connections (plates) to allow the added
structure to contribute more to the stiffness of the assembly. Omega brackets can be used on vehicles where these are
originally fitted.
3. The rear tipping hinge must be fitted to the subframe; its position must be as close as possible to the rear support of the rear
suspension. So as not to compromise vehicle stability during tipping operations and avoid excessive mechanical stress on the
chassis, the distance must comply with the specifications given in Figure 11. If this is not possible, the subframe profiles must be
larger than normal and additional reinforcement must be applied to the rear.
4. Particular attention must be paid to the positioning of the lifting device both in terms of providing supports with adequate
strength and in order to correctly position the connections. In any case, in order to reduce the extent of the localised load, it is
recommended that the lifting device is placed forwards of the centre of gravity of the payload-body assembly.
5. For rear tipping operations, it is recommended that a stabilizer is fitted to guide the body, particularly when the lifting cylinder
is located behind the cab.
6. The lifting device hinge must be mounted on the additional subframe. The useful volume in the body must conform with the
maximum 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 low density freight, the useful volume may be increased within
the limits established for the maximum height of the centre of gravity of the payload (plus equipment).
7. The bodybuilder must ensure the good operation and safety of all parts of the vehicle (e.g. the positioning of lights, tow hook
etc.) and ensure that, following the addition of the structure, vehicle stability is guaranteed during tipping operations.
▶ The air springs must be completely discharged during unloading operations, to ensure stability
of vehicles equipped with air suspensions. There must also be a nameplate highlighting this indic-
ation.
