3.8.1
Crane behind the cab
The fastening of the reinforcement sections to the chassis must be carried out using the standard brackets (see Figure 15), sup-
plementing them, if necessary, with other fasteners of elastic type (brackets or clamps) in order to keep the flexural and torsional
characteristics of the chassis as unchanged as possible. The dimensions of the reinforcement sections to be used for this type of
connection are shown in Table 3.6.
On vehicles for road use only, shearing resistant connections may be used for fastening the subframe to reduce the subframe sec-
tion height. The minimum reinforcement section dimensions for all these applications are given in Table 3.7.
The implementation of constant diameter sections for the entire length of the vehicle is recommended.
The section of the crane subframe (Figure 15) can be integrated towards the rear end with that envisaged for another possible
superstructure; the length "L
V
" must in no case be less than 35% of the wheelbase if the superstructure section diameter is smaller.

Stabilisers
In installations of cranes on vehicles with deep cab (e.g. 6 +1), the subframe must continue to underneath the cab (see Figure 3),
otherwise, depending on the capacity of the crane, it will be necessary to limit the crane's range of rotation, so as not to exceed the
permissible bending moment from the chassis.
The application of a crane on vehicles for on-off road use requires flexible connections to be made between the chassis and the
subframe (see Figure 8) in the front and middle section so as not to excessively constrain the torsional movement of the chassis.
The crane is practically connected to the subframe only, the dimensions of the longitudinal sections must therefore be suited to
withstand the moment induced during use.
The container or equipment must normally be retracted to arrange the crane behind the cab. In the specific case of tipping equip-
ment, particular attention must be paid to arranging the mounts of the lifting device and the tipper rear hinges which must be as
retracted as possible.
