BUILDING & MOUNTING THE STRUCTURES 3-15 E UROCARGO Euro 4/5 3.3.5 Connection with U-bolts (clamps) The most important mounting of this type is illustrated in Figure 3.12. In this type of construction the bodybuilder must place metal spacers, between the flanges of the two side members and in the subframe at the point where the U-bolts are located, in order to prevent the flanges bending when the U-bolts are tightened. In order to guide and contain transverse movement of the structure attached to the vehicle’s chassis, this type of connection must also have guide plates that are attached only to the chassis as shown in Figure 3.12.
In order to keep the added structure from sliding and to increase the rigidity, it is necessary to provide positive attachment towards the rear with cleat plates to contain both longitudinally and transversal movement. Alternatively it is also possible to use bolt-type connections at the rear end of the chassis as illustrated in Figure 3.13. Figure 3.12 1. Frame - 2. Subframe - 3. U-bolts - 4.
