3. Loads that result in increased aerodynamic actions
In outfits 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,
●
prescribing the implementation of adequate precautions for driving.
Any cases where evaluation is difficult should be submitted to IVECO for approval.
implementation of stabiliser bars
The application of additional or reinforced stabiliser bars, where available, reinforcing the springs or rubber elastic elements (in
accordance with the procedure outlined in Section 2.7), may allow higher values of the centre of gravity of the payload, to be de-
termined from time to time. The operation must be carried out after a careful evaluation of the features of the outfit, the wheel-
base and the subdivision of lateral 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 can be made in the presence of concentrated loads behind the cab (e.g. cranes) or superstructures with high ri-
gidity (e.g. vans).
Exceeding the limits
In the case of special transport with a high centre of gravity height (e.g., transport of machinery, indivisible loads, etc.), from a tech-
nical standpoint it is possible to exceed the values shown in the table, provided that the driving is adjusted appropriately (e.g. re-
duced speed, gradual variations of the trajectory of travel, etc.).
Respect of the permitted masses
All the limits shown on IVECO documentation must be respected. It is particularly important to evaluate the maximum ground on
the front axle in any load condition, in order to ensure the necessary steering features in all road surface conditions.
Special attention must therefore be paid to vehicles with concentrated load on the rear overhang (e.g.: cranes, tail lifts, central axle
trailers) and vehicles with a short wheelbase and high centre of gravity height (e.g. silo vehicles, concrete mixers).
Note In the positioning of the auxiliary bodies and superstructure, a proper load distribution in the transverse direction must be ensured.
A variation on the nominal load may be permitted for each wheel (50% load on the corresponding axle) of
±
4% (e.g.: load allowed
on the axle 10,000 kg; allowed for each wheel side from 4,800 to 5,200 kg) in compliance with what is permitted by the tyres,
without affecting the braking and driving stability characteristics of the vehicle.
Unless otherwise specified individual vehicles, the minimum values of the mass on the front axle must be:
–
20% of the actual mass of the vehicle, if the load is evenly distributed,
–
25% of the actual mass of the vehicle, if the load is concentrated on the rear overhang.
Actual mass is meant to include any vertical load resulting from the trailer.
The rear overhang of the superstructure must be realized in observance of the admissible axle loads, the minimum required load
on the front axle, the length limits, positioning of the tow hook and under-run protection, provided for by the various Standards.
