CHASSIS MODIFICATIONS 2-55 E UROCARGO Euro 4/5 2.13.3 Fitting a spoiler or a top-sleeper On request the IVECO versions can be available, with the relevant assembly instructions. It is recommended to use them, as they have been specially designed and tested. The application of other solutions must be performed in a similar manner as for the original ones, via the specific fastening points on the sides of the roof assembly, using supporting devices of suitable dimensions. Follow the instructions of the manufacturers of the added assemblies. Their positioning must not jeopardize the good working conditions of the engine air intake.
When the national standards require it, these installations must be checked by the relevant Institutes. 2.13.4 Construction of crew cabs When making crew cabs, cabs for special vehicles, for municipal uses, fire brigade, etc., it is necessary to check the need to adjust the cab suspension, due to the greater mass, also taking account of any extra seating added. The possibility to doing work of this type on the tipping cabs requires confirmation from IVECO for the suitability of the original devices for the suspension, tipping and locking. Generally, it is possible to implement equivalent solutions to those used by IVECO for similar versions.
To help preserve the integrity and rigidity of the cab, it is recommended to keep the rear structure as intact as possible. The cut can be made sideways, keeping the ring of the door bay integral. The bodybuilder must make the necessary connections to the framework, composed of the longitudinal sections and the uprights and connect the new floor to the existing structure. Make provision for inspection panels, if necessary. Take special care of the surface preparation of the elements to be welded using a zinc primer, taking the necessary precautions for proper preparation of the base for subsequent painting (see point 2.2).
If you want to maintain the cap tipping function, on the basis of the increase in mass, make provision for: - Work on the tipping devices. - Restoring the coupling devices. - Reducing the tipping angle. - Adjusting for the suspensions. For the tipping system it may be possible to install a cylinder with related supports of greater capacity or apply an additional cylinder, verifying observance of the minimum distances from the elements located nearby. The zones affected by the thrust of the hydraulic devices must be taken care of so as to avoid an excessive concentration of the stresses; for this purpose make provision for: - Locating the lifting points as far back as possible.
- Suitable anchorage zones both on the bottom of the cab and on the vehicle chassis frame. If in the tipping phase, the cab exceeds the upper point of equilibrium, make sure that the added hydraulic device enables keeping the cab in the limit stop position, on the contrary apply a safety rope. Take the necessary precautions to permit correctly coupling the cab in the phase of closing. The rear coupling device of the original cab has a safety latch and an indicator that signals closure. We recommend keeping this solution complete. In the definition of a suitable elastic system of the cab suspension, it will be necessary to: - Respect the cab driving position of the standard vehicle.
- Prevent the added mass from weighing on the original part of the cab and on the related suspension. - Ensure the normal oscillations of the cab along the vertical, longitudinal and transverse planes. Cab modifications Print 603.93.431 Base - January 2008
