Crane at rear overhang
The counter chassis should extend for the entire length of the vehicle to the rear part of the cab; The dimensions of the longitud-
inal sections are shown in Table 3.11.
Considering the particular distribution of weights on the vehicle (load concentrated on overhang) and to ensure the necessary
torsional rigidity for good performance on the road and during the working phase of the crane, the counter chassis must be suitably
stiffened in relation to the crane capacity. Box sections and cross bracings must be used (see Chapter 3.2 (
➠
Page 7)) at the rear
suspension and for the entire rear overhang (distance L
V
) - see Figure 3.24.
The passage between box section s and open sections must be well fitted as shown in Figure 3.3.
Shear resistant connections (a sufficient number of plates spaced at a maximum distance of 700 mm) must be used in the box
section for fastening to the chassis, given that elastic fastenings are used on the front end. Check that the ratio between the front
axle and rear axle weight respects the limit defined for each vehicle under any load condition (see Chapter 1.15 (
