▶ The Bodybuilder must, case by case, check the vehicle stability and take all necessary precau-
tions for its correct and safe use. The crane manufacturer and the Bodybuilder are responsible
for defining the type and number of stabilisers as well as selecting the counter chassis on the
basis of the maximum static moment and the position of the crane.

The fastening of the reinforcement sections to the chassis must be carried out using the standard brackets (see Figure 3.19), sup-
plementing them, if necessary, with other fasteners of elastic type (brackets or clamps) in order to keep the flexural and torsional
characteristics of the chassis as unchanged as possible. The dimensions of the reinforcement sections to be used for this type of
connection are shown in Table 3.7.
On vehicles for road use only, shearing resistant connections may be used for fastening the counter chassis to reduce the counter
chassis section height.
The implementation of constant diameter sections for the entire length of the vehicle is recommended.
The section of the crane counter chassis (Figure 19) can be integrated towards the rear end with that envisaged for another pos-
sible superstructure; the length “L
V
” must in no case be less than 35% of the wheelbase if the superstructure section diameter is
smaller.
