Elements making up the subframe
3.2.2 Cross members
A sufficient number of cross members, to be positioned near the fastenings of the chassis, must brace the two profiles of the
sub-frame.
Cross members can have an open section (e.g. C-section) or a closed section if greater rigidity is required.
Use suitable plates when connecting them, so as to provide appropriate resistance (see Figure 3.4). When greater connection rigidity
is desired, construction can be performed as per Figure 3.5.

Stiffening the subframe
The sub-frame must be made more rigid in the rear part for some structures (e.g. tilting bodies, cement mixers, cranes on the
rear overhang, structures with high centre of gravity).
This can be performed with a greater amount of rigidity to achieve:
- joining the rear section of the longitudinal member by a box-frame construction;
- box-frame construction, closed-section cross members (see Figure 3.6);
- box-frame construction, crossties (see Figure 3.7).
These solutions can be combined.
Generally speaking, using longitudinal boxed profiles must be avoided in the front part of the sub-frame.
