3.5 TRACTOR FOR SEMI-TRAILER
Note The range does not include vehicles designed to tow trailers. To carry out conversion of a cab vehicle (in category N2 or N3), a
specific IVECO authorisation is required.
This authorisation provides the indications that the body builder must observe, the masses allowed and provisions on use. Below are
some general indications.
Fifth wheel supporting structure
The application of a suitable secondary chassis structure (see Figure 17) in addition to distributing the load on the fifth wheel,
provides a suitable torsional and bending contribution for the vehicle. The minimum sizes of the longitudinal sections are shown in
Table 3.6.
To implement this, it should also be noted that:
●
the structure must be suitably dimensioned for vertical and horizontal loads which the fifth wheel transfers;
●
the material characteristics of the structure must refer to what is set out in Chapter 3.1 (
➠
Page 5).
●
the upper and lower surfaces of the structure must be level so as to ensure a good contact on the chassis;
●
the structure components, when this is formed by several elements, must be welded and/or nailed to form a single assembly;
●
the structure should be fastened to the tractor by means of cleat plates in the middle and back of the chassis and brackets in
the front. For fastening, use screws of a minimum class of 8.8 (number and diameter so as to achieve a tightening resistant to
longitudinal and transversal forces) and use systems that prevent unscrewing.
