3.8 Installation of cranes
The choice of crane type must be based on its characteristics and on the vehicle performance.
Placement of the crane and payload must respect the load limits allowed for the vehicle. When applying the crane, respect specific
regulations, national norms (e.g. CUNA, DIN) and international norms (e.g. ISO, CEN) and check what is required for the vehicle.
As a general rule, to install the crane a sub-frame must be fitted, built according to the general instructions (see point 3.1) and with
profiles having sizes as per Tables 3.8, 3.9 and 3.10.
The longitudinal runners can also be determined by calculation, the dimensions refer to the total maximum static moment of the
crane (M
G
) and is the moment of the crane + the moment of the load which is calculated on the basis of the equation given below
in Figure 3.19.
If the vehicle version (e.g. tilting body) requires a profile with greater resistance modulus than that required for the crane, that profile
can be considered valid for the crane as well.
Particular cases when the values of the M
G
moment correspond to value ”E” in Table 3.8 (or greater values) must be checked from
time to time and must be expressly authorized by IVECO.

= weight applied to the end of the crane [kg];
L = horizontal distance between the point where load WL is applied and the vehicle centre line [m];
Wc = crane’s own weight applied to its centre of gravity [kg];
l = horizontal distance between the centre of gravity of the crane and the vehicle centre line [m].

The Bodybuilder must verify each time the vehicle’s stability and take all the necessary precautions to
ensure correct operation. The crane Manufacturer and the Bodybuilder share the responsibility in
defining the type and quantity of stabilizers, as well as constructing a sub-frame according to the
maximum static moment and the position of the crane.
