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, trailers with
centre axle) and short wheelbase vehicles and high centre of gravity.
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 3,000 kg; allowed for each wheel side from 1,440 to 1,560 kg) in compliance with what is permitted by the tyres,
without affecting the braking and driving stability characteristics of the vehicle.
Unless other specific dispositions are provided for individual vehicles, one must consider for the mass on the front axle a minimum
value of 25% of the effective mass of the vehicle (with loads distributed uniformly as well as with loads on the rear overhang or
associated with a trailer, if attached).
The rear overhang of the superstructure must be implemented in full compliance with the permitted axle loads, the minimum load
required on the front axle, length limits, the position of the tow coupling and the under-run protection as envisaged by various
standards and regulations.
Variations on permitted masses
Special exemptions from the maximum permissible masses may be granted for specific uses, for which, however, there are precise
limits for use and reinforcements to be made to parts of the vehicle.
These exceptions, if they exceed the limits of the law, must be authorised by the Administrative Authority.
In the authorisation request, you must indicate:
● type of vehicle, wheelbase, chassis number, intended use;
● division of the tare weight on the axles (in fitted vehicles, e.g.: crane with flatbed), with the position of the payload centre of
gravity;
● any proposals for strengthening the parts of the vehicle.
The permitted reduction of mass on vehicles (derating), can lead to interventions on some parts, such as suspensions and brakes,
and may require a new calibration for the braking correction operation; in these cases the necessary indications may be provided.
1.16 INSTRUCTIONS FOR PROPER FUNCTIONING OF THE VEHICLE PARTS AND ACCESS-
IBILITY
In carrying out the transformations and applying any type of equipment, there should be no alteration to what enables the proper
functioning of the vehicle units and parts under various working conditions.
For example:
● free access must be guaranteed to the places that need inspection, maintenance or periodic controls (e.g., battery replace-
ment, access to the air suspension compressor) and, in the case of enclosed superstructures, special compartments and doors
should be provided;
● the possibility of disassembling the various groups for assistance operations must be maintained;
● in the fitting that provides the tipping of the lateral tails, consider the size of the most protruding parts of the vehicle, in order
to avoid limitations to tipping or damage to the parts.
● conditions should not be affected regarding cooling (radiator grille, radiator, air passages, cooling etc.), fuel supply (pump posi-
tioning, filters, pipe diameter, etc.) and engine air intake;
● the soundproofing panels must not be altered or moved so as not to affect the approved sound emission limits. If any open-
ings need to be made (e.g. for the passage of pipes or added sections), they must be thoroughly closed, using fireproof and
soundproofing materials equivalent to the original materials used;
