2-36 CHASSIS MODIFICATIONS E UROCARGO Euro 4/5 Table 2.15 - Solutions with sections for reinforcement with combined cross-sections The possibility of interrupting the continuity of the combined reinforcements is limited to particular cases and must be authorized. Likewise when the application of the external reinforcement angle piece (solution C and D, see Figure 3.24) is difficult (e.g., presence of suspension supports or air spring brackets) and the slot to make could reduce the strength of the section too much, the solution must be submitted for approval with the proposed reinforcements. 2.6.4.2 Centre axle trailers:
towing cross member in lowered and forward positions (short coupling) Vehicles designed to tow centre axle trailers for which a final cross member located in a lowered or forward position (next to the rear suspension rear mountings or air springs) is evisaged, do not require particular chassis reinforcing devices. For the subframe, the runner profile dimensions indicated for the different types of equipmen t (e.g. see Table 3.4 standard bodies) will be sufficient. The bodybuilder will accurately work out the size and position of the chassis connection structure (see point 2.6.3 and 2.6.4.1) and make use of a suitable cross member and an appropriate towing hook.
The tow hook position will be such to permit any movement between vehicle and trailer drawbar according to the various conditions of use, to comply with the required safety margins and the standards and legal regulations in force (where applicable). In these cases the standard underrun bar cannot be used, and the bodybuilder will investigate the possible permitted changes from specifications or the specific solutions to adopt (e.g. tilt type underrun bar).
2.6.4.3 Reinforcement of standard rear cross member When it is necessary to reinforce the standard cross member and when original cross members are not available, the bodybuilder will provide suitable reinforcements for which he shall be responsible. These reinforcements may consist of C-sections mounted on the inside of the cross member. Care must be taken to ensure that the connections between the cross member and the side members are also reinforced following the procedures recommended below, whenever stronger enforcements are required:
1) The mounting of a channel section on the inside of the cross member and joining it to the vertical web of the side member or to the following cross member of the chassis, if it is situated in close proximity, in compliance with the procedures illustrated in Figure 2.14.
