Cross members
A sufficient number of crossbars, possibly to be placed in correspondence with the fastening clamps to the chassis, must brace the
two sections of the counter chassis.
The crossbars may be open section (e.g. C), or closed section where you would want to impart greater stiffness.
In their connection, suitable gusset plates must be used to give adequate resistance to the connection (see the following Figure on
the left). When you want to achieve greater stiffness in the connection, it can be carried out according to the following Figure on
the right.

Stiffening of the counter chassis
For some superstructures (e.g. tipping bodies, concrete mixers, cranes on rear overhang, superstructures with high centre of grav-
ity), the counter chassis should be stiff in the back.
This can be achieved by increasing the scope of stiffness to obtain:
●
boxing the longitudinal sections in the rear area;
●
adopting closed section crossbars (see Figure 6);
●
applying cross diagonals (see Figure 7);
In general the use of boxed longitudinal sections should be avoided in the front part of the counter chassis.
