3-42 BUILDING & MOUNTING THE STRUCTURES E UROCARGO Euro 4/5 Table 3.14 - Installation of tail lifts, maximum permissible bending moment at (subframe fastening with shear-resistant plates) Should a reduction in the height of the subframe section be required, using shear-resistant connections between the chassis frame and subframe, in place of the channel section it is possible to use structural elements with combined sections, as indicated in Table 3.15, provided the width of the flange and the thickness are not less than the corresponding values for the structural element indicated in Table 3.13. These conditions of a general nature apply to the stated materials.
The possibility of using materials with superior mechanical characteristics requires verifying the total moment of resistance of the chassis frame plus subframe.
