1.16 INSTRUCTIONS FOR PROPER FUNCTIONING OF THE VEHICLE PARTS AND ACCESSIBILITY
– Printed 692.68.999 – 3 Ed. - Base 08-2020
1.15.8 Variations on the 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.
Reduction of the permitted mass on the vehicles (downgrading) can lead to interventions on the suspensions and brakes; 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;
● adequate ventilation must be maintained for the brakes and battery casing (particularly in the execution of truck bodies);
● in the placement of fenders and wheel arches, free shaking of the rear wheels must be guaranteed, even under the conditions
of use with chains.
● adjustment of the vehicle's headlamps must be checked once construction is completed, to correct any changes in their struc-
ture; for adjustment, proceed according to the instructions given in the "Use and Maintenance Handbook";
● for any elements supplied loose (e.g. spare wheel, chocks), the Body builder must position and fasten them in an accessible and
secure way, in compliance to any national regulations.
