BUILDING & MOUNTING THE STRUCTURES 3-29 E UROCARGO Euro 4/5 Figure 3.20 The installation of two or more separate containers or tanks on the vehicle requires the use of subframe that permits good distribu- tion of the load and an adequate torsional rigidity for the chassis/subframe using connections resistant to shearing. A good solution is constituted by using a rigid connection which connects the containers together. In order to adhere to the maximum admissible load limits on the axles, it is necessary to establish the maximum volume, the degree of filling of the container and the density of the freight.
When separate tanks or individual containers with separate compartments are used, care must be taken to ensure that with every degree of filling the maximum permissible load on the axles is respected as well as the minimum ratio between the load on the front axle and fully loaded vehicle weight (see point 1.13.2). In consideration of the nature of this equipment, special attention must be paid to limiting the height of the centre of gravity as much as possible to ensure good handling (see point 1.13.2); we recommend the use of vehicles with stabiliser bars.
It is necessary to provide special transverse and longitudinal bulkheads inside the tanks and containers for liquids in order to reduce the dynamic loads which the liquid transmits when the vehicle is in motion and the tanks are not filled to capacity which would adversely affect the handling and resistance of the vehicle. The same holds true for trailers and semitrailers, in order to avoid dynamic loading on the coupling devices. Concerning the installation of containers for fuel or flammable liquids, all current government safety regulations must be abided by (see point 2.18).
