1. Combined reinforcement
2. Shear resistant connections
3. Longitudinal counter chassis section
4. Vertical static load on the towing hook
Use sections with a greater resistance modulus if the superstructure requires it. Check from time to time the need to install a suit-
able towing crossbeam and a suitable hook.

The possibility of interrupting the combined reinforcement continuity is limited to special cases and must be authorized. Similarly,
when the application of the external reinforcement angle (solutions C and D see Figure 3.24), presents difficulties (e.g. presence of
suspension supports, or of the coupling brackets of the air spring) and the recess to perform could reduce excessive the resistance
capacity of the section, the solution must be submitted for approval with the proposed reinforcements.
Rear crossbar in lowered position
When the drawbar coupling must be lowered from its original position, IVECO may issue an authorisation to lower the original
drawbar or install an additional drawbar, which is the same as the original, in a lowered positioned.
Figures 2.12 and 2.13 show the respective realisation examples.
Connection of the drawbar in its new position must be performed in the same way and using screws of the same type (diameter
and resistance class) in relation to the original connection.
Anti-unscrewing systems must be used in the connections.
