3.5 Tractor for half-trailers
The range does not envisage special vehicles for towing semitrailers.
However, it is possible to make the conversion using the chassis-cab vehicle, with specific authorization issued by IVECO.
This authorisation provides the instructions that the Bodybuilder must follow, the allowed masses and the prescriptions for use.
Below are some general instructions.
Fifth wheel mounting
The application of a suitable structure of the sub-frame type (see Figure 3.17) has the purpose of distributing the load on the
fifth wheel and ensuring the vehicle chassis a suitable torsion and flexion support. Table 3.6 gives the minimum dimensions to use
for the longitudinal runner sections.
Furthermore, take the following into consideration for its construction:
- the structure must be sized appropriately for vertical and horizontal loads transmitted by the fifth wheel;
- the characteristics of the structure material must refer to point 3.1.
- the upper and lower surfaces of the structure must be flat to ensure good support on the chassis;
- the components of the structures, when constituted by several elements, must be connected by means of weldings and/or nails
so as to constitute a single assembly;
- fastening the structure to the tractor must be performed by means of shear resistant plates in the central and rear part of the
chassis and by means of shelves in the front part. For the connection use at least 8.8 class screws (in quantity and diameter such
as to perform a fastening resistant to longitudinal and transversal forces) and use loosening prevention systems.
