BUILDING & MOUNTING THE STRUCTURES 3-43 E UROCARGO Euro 4/5 Interchangeable outfits In the case of self-bearing bodies with the framework acting as a subframe, it is possible to omit the application of the above-men- tioned reinforcement structural elements. The application of box-bodies, and more generally structures with great torsional rigidity, requires, especially when the vehicle is used for heavy-duty work, using flexible connections toward the front of the structure to avoid excessive reduction in thedeformabil- ity of the main chassis frame.
The front panel of the bodywork must have the necessary resistance and sturdiness to withstand, in the case of sharp and marked deceleration, the thrusts generated by the transported load. 3.9 Interchangeable outfits Interchangeable outfits that are lifted for the operation of replacement (e.g. with lifting devices or with thevehicle’s airsuspension) and are later positioned on four supports are as a rule made when using a subframe with longitudinal structural elements of the size of those given in Table 3.4, or with suitable structures including the lifting and connecting devices.
If the concentrated loads transmitted by the lifting systems produce great strains on the vehicle’s chassis frame, provision must be made for suitable reinforcements. To assure proper functionality the various conditions of the vehicle driving position must be carefully checked according to the char- acteristics of the suspension. Models equipped with rear axle or full pneumatic suspension can be particularly suited for these applica- tions. The lifting devices acting in the vertical direction, as well as to the subframe will be able in particular cases to be anchored to the connection plates between the chassis frame and subframe, provided they are of suitable dimensions.
For the body connections, especially when fast closing systems are used, verify that the longitudinal and transversal thrusts that occur under dynamic conditions are adequately withstood. The possibility of doing without a subframe or a specific sub-structure can be allowed, with IVECO authorization, under the following conditions: - the interchangeable body must adhere all along the chassis frame of the vehicle or at least a large surface area of the suspension connection zones; - the connection devices, of a suitable number, must be secured on the vertical rib of the structural members; - the lifting devices must be anchored so as to transmit limited stresses to the chassis frame.
