For any inspections with the vehicle set up without payload you can proceed similarly, assuming Ws is only the tare weight of the
superstructure (considering for Hv a value appropriate for the load and between the no-load cab version trim and the full-load
trim).
For any inspections of the vehicle set up with payload, the maximum height of the centre of total weight (payload + body and/or
equipment), referring to transverse stability is 1590 mm.
b) Mobile loads
In the versions where the load can be moved laterally while cornering (e.g.: suspended loads, liquid transport, animal transport,
etc..) high lateral dynamic forces may be generated which may jeopardise the stability of the vehicle.
With reference to the indications of ECE 111, special attention should therefore be paid:
● in defining the height of the fitted vehicle's centre of gravity and at full load;
● in assessing the dynamic forces and the lateral displacement of the centre of gravity;
● in considering (for liquids) the density;
● in prescribing the adoption of adequate precautions for driving.
Any cases where evaluation is difficult should be submitted to IVECO for approval.
c) Loads that result in increased aerodynamic actions
In fittings characterised by high vertical and surface development (e.g.: advertising panelling), the hight of the centre of thrust, de-
termined in the case of cross-wind, must be evaluated very carefully.
▶ Even with the low centre of gravity, a vehicle fitting that has a high surface area may not provide
sufficient lateral stability and may be exposed to the danger of tilting.
Special attention must therefore be paid:
● in defining the height of the fitted vehicle's centre of gravity and at full load,
● in assessing the aerodynamic forces,
● in prescribing the adoption of adequate precautions for driving.
Any cases where evaluation is difficult should be submitted to IVECO for approval.
Adoption of stabiliser bars
The application of additional or reinforced stabiliser bars, where available, reinforcing the springs or rubber elastic parts (in accord-
ance with the procedure outlined in Chapter 2.9 ( ➠ Page 18)), may allow higher values of the centre of gravity of the payload, to
be determined on a case by case basis. The operation must be carried out after careful evaluation of the outfitting characteristics,
the wheelbase and the distribution of transverse forces on the suspension, and should generally concern both the front and the
rear. However, it should be kept in mind that in many cases it is advisable to carry out the operation only on the rear axle; acting on
the front axle would give the driver an incorrect sensation of greater stability, making it actually harder to perceive the safety limit.
Interventions on the front axle may be performed in the presence of concentrated loads behind the cab (e.g. cranes) or of super-
structures with high rigidity (e.g. vans).
