It is necessary to create continuity of support between the profiles of the counter chassis and those of the chassis; if this is not ob-
tained, the continuity can be restored by means of interposition of strips of sheet metal or light alloy.
If there is to be a rubber undercrawl element we recommend characteristics and thicknesses similar to those used for normal
production (hardness 80 Shore, max thickness 3 mm). Its use can prevent abrasive actions that can cause corrosion in the joining
between materials of different composition (e.g. aluminium and steel).
The dimensions prescribed for the side members of the various types of superstructures are the recommended minimum values
and, as a rule, are valid for vehicles with wheelbases and rear overhangs provided as standard (see Tables from 3.4 to 3.8). In all
cases similar profiles can be used, but with moments of inertia and resistance that are not lower. These values can be obtained
from the technical documentation of the profile manufacturers.
