In installations of cranes on vehicles with deep cab (e.g. 6 +1), the counter chassis must continue to underneath the cab (see Figure
2), otherwise, depending on the capacity of the crane, it will be necessary to limit the crane's range of rotation, so as not to exceed
the permissible bending moment from the chassis.
Elastic connections between chassis and counter chassis (see Figure 8) may be needed to avoid excessive constraint on the chassis
torsional movement for application of crane on off-road vehicles on the front and middle parts. The crane is practically connected
to the counter chassis only, the dimensions of the longitudinal sections must therefore be suited to withstand the moment induced
during use.
The container or equipment must normally be retracted to arrange the crane behind the cab. In the specific case of tipping equip-
ment, particular attention must be paid to arranging the mounts of the lifting device and the tipper rear hinges which must be as
retracted as possible.

When a higher modulus of resistance is required for the superstructure also use the latter for the crane.
