a) Fixed loads

Figure 6
Control at full load
Hw = Vehicle centre of gravity height (loaded)
Hs = Height of payload centre of gravity from the ground
Ht = Complete full-load vehicle centre of gravity height
Ww = Vehicle tare weight
Ws = Payload
Wt = Complete vehicle ground at full load
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 chassis cab version trim and the full-
load trim).
The following table lists the maximum indicative heights of the overall centre of mass of the outfitting (payload + dump body
and/or equipment) with reference to the crossways stability of the vehicle.
Table 1.1
Tyres
225/75 R16
twin wheels
265/70 R19.5
single wheel
255/100 R16
T.G.W. [kg] 7000 7000 5500
Max. mass on front axle [kg] 2700 2700 2450
Max. mass on rear axle [kg] 5000 5000 3700
Height of centre of mass of outfitting [mm] 1620 1670 1710
Height of centre of mass of vehicle complete with load [mm] 1480 1510 1500
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 the regulation ECE 111, special attention should therefore be paid to:
● 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.
