Installation of tanks and containers for bulk materials
When installing the crane on vehicles with deep cab (e.g. 6+1), extend the sub-frame all the way up to the cab (see Figure 3.2),
otherwise the rotation field of the crane must be limited according to the crane capacity in order not to exceed the flexing moment
allowed by the chassis.
When installing the crane on vehicles to be used on poor roads, elastic connections between chassis and sub-frame must be fitted
(See Figure 3.8) in the front and central part in order not to limit excessively the torsion movement of the chassis. Since the crane
is connected only to the sub-frame, the size of longitudinal profiles must be suitable to support the generated moments.
The function of vehicle elements located behind the cab (e.g. fuel tank) must not be hindered; they can be moved as long as the
same type of original connection is restored.
Placing the crane behind the cab usually requires moving back the tray or equipment. In the case of tilting equipment, take particular
care in placing the supports of the device and the rear tilting hinges, which must be moved back as little as possible.

Close the reinforcing runner in the crane mounting area.
E = To be checked from case to case (submit the technical documentation with the calculation made to determine stress and stability).

When the subframe requires a high moment of resistance the latter shall be established also for the crane.
Tables 3.8 and 3.9 show that the subframe material yield limit is 360 N/mm
