2.13.2 Interventions on chassis cab vehicles
a) Cab
Any cab modifications performed to create specific configurations must be done with care in order to protect the resistance and
maintain cab functionality and protections intact.
In the installation of units on the roof (e.g. air-conditioning systems), make sure that the weight of the equipment does not exceed
that permitted by the cab. The applicable limits can be provided on request, depending on the version.
If an opening has to be made, the following is required:
● envisage coupling radii of no less than 50 mm;
● do not modify any ribbing that may be present;
● do not modify the curvature of the roof.
b) Installation of spoiler or box on the roof
On request, versions are available developed for IVECO on the basis of its design and verifications.
If "kits" of other origins are fitted, follow the specific indications supplied by the manufacturer.
In any case, please note that the possible lack of contact between the superstructure and roof may trigger air turbulence resulting in
fastidious vibrations or resonances; therefore the application of gaskets or sealing systems that protect the aerodynamics is strongly
recommended.
If the national standards require it, these installations must be controlled by relevant type-approval authorities.
c) Roof and cab rear wall
If the rear wall and part of the roof have to be removed (e.g. auto-caravan set-ups), bear in mind the following indications:
● make the cut as shown in Figure 16 ensuring that the minimum coupling radius as indicated is observed;
● eliminate the rear cross member structure at roof level;
● implement a structure capable of ensuring that uprights cannot be deformed in order to retain the efficiency of the upper
couplings of the safety belts;
● this structure should have a compression strength of at least 800 daN;
● implement the connection with the new structure following the general indications provided above.
