Dimensions and masses
Using Stabiliser Bars
Supplementary stabilising or anti-roll bars, where available, spring reinforcements or the application of rubber components (in
compliance with point 2.11) may increase the height of the centre of gravity of the payload which must be defined as each occasion
arises. The modification must be carried out after careful consideration has been given to the specifications of the version, to the
wheelbase and to the distribution of the cross-stresses acting on the suspension both at the front and at the rear of the vehicle.
It must be borne in mind that it is often advisable to modify the rear axle only since a modified front axle would give the driver a
false sense of stability making it more difficult to perceive the safety limits. Modification to the front axle may be made where the
load is positioned behind the cab (e.g. crane) or where the superstructures are very rigid (e.g. van conversion).
1.13.3
Observing the Permitted Weights
All the limits specified on the IVECO documents must be complied with. It is essential that
the maximum weight on the front
axle is not exceeded
, under any load condition, so as to ensure the correct steering and braking characteristics regardless of the
road surface conditions.
Particular attention must be taken with vehicles where the load is concentrated on the rear overhang (e.g. cranes, tail lifts, trailers)
and to vehicles with short wheelbases and a very high centre of gravity.
Ensure transverse loads are properly distributed when positioning auxiliary components and superstructures. A +4% variation on
the rated load (50% of load on the axle) is permissible for each wheel (for example: permissible load on axle 3000 kg; 1440 to 1560
kg allowed for each wheel side); in compliance with load allowed by tyres, without affecting braking properties and vehicle driving
stability.
Apart from different specifications for specific vehicles, the following may be taken to be the minimum weights for the front axle:
30% of the total vehicle weight (with uniformly distributed loads and with loads concentrated on the rear overhang).
The rear overhang of the body must be built in strict observance of the permitted axle loads, the minimum load required on the
front axle, the limitations in length, the positioning of any tow hook and of the rear under-run guard stipulated by the relevant
National and EC regulations.
Variations in the Permissible Weight
Special exceptions to the maximum permissible weights may be granted for particular applications for which, however, precise
limitations regarding the use will be imposed in addition to possible vehicle reinforcements.
Such exemptions, if they exceed the limits imposed by law, must be authorised by the Government Administrative Authority.
The request for authorisation must include:
-
vehicle type, wheelbase, identification number, designated use;
-
unladen weight on the axles (e.g. vehicles equipped with crane) including positions for the centre of gravity of the payload;
-
proposals concerning the reinforcement of the vehicle components where necessary.
The reduction in the permissible weight on the vehicle (derating) may involve changing various components such as suspension,
brakes etc) and may require recalibration of the load sensing valve where one is fitted. In these circumstances necessary instructions
may be provided.
