3.8 INSTALLING A CRANE
The selection of the crane must be made with due consideration to its characteristics and in relation to the performance of the
vehicle.
The positioning of the crane and of the payload must be done within the load limits permitted for the vehicle. Installation of the
crane must be carried out in compliance with statutory requirements, national standards (e.g. CUNA, DIN) and international stand-
ards (e.g. ISO, CEN) and verifying those required for the vehicle.
While the crane is operating, the stabilizers (hydraulic if possible) must be used and be in contact with the ground.
As a general rule, the installation of a crane requires the use of a suitable subframe, the construction of which must take into ac-
count the general specifications (see Chapter 3.1 ( ➠ Page 5)), and with the dimensions of the sections given in Tables 3.6, 3.7 and
3.8.
The dimensions of the subframe section modulus refer to the maximum total static moment of the crane (M
G
), deduced from the
formula shown in Figure 14.
If the vehicle outfitting requires the use of a section with section modulus greater than that required for the crane (e.g. tipper), this
section may also be considered for the crane.
Special cases in which the moment M
G
values correspond to the "E" value in the Table (or for higher values) must be checked indi-
vidually each time and must receive specific authorisation from IVECO.

= mass of the crane at its centre of gravity [kg]

▶ The Bodybuilder must, case by case, check the vehicle stability and take all necessary precau-
tions for its correct and safe use. The crane manufacturer and the Bodybuilder are responsible
for defining the type and number of stabilisers as well as selecting the subframe on the basis of
the maximum static moment and the position of the crane.
