3.10 TILT BEDS (BREAKDOWN RECOVERY)
Using a tilt bed typically subjects the chassis to considerable stress. The vehicle used should therefore specifically indicated for this
application. These vehicles are listed in Table 3.5 together with the indicative characteristics for the counter chassis necessary
Where a very long bed is necessary, it is preferable to use a vehicle that already has a sufficiently long wheelbase rather than create
a long overhang.
The counter chassis must be suitably sized and stiffened at the rear with boxing and diagonal crossbraces (see Figures 6 and 7).
Connections to the chassis must be elastic (brackets or supports) at the front end and stiff at the rear end (cleat plates, see Figure
11) to allow the additional structure to contribute more effectively towards the rigidity of the assembly.
The rear tilt pivot must be installed on the counter chassis, and must be situated longitudinally as close as possible to the rear sus-
pension mount. To prevent the risk of the tilt bed compromising vehicle stability when operating and to avoid excessively increasing
the stress sustained by the chassis, the distance between the tilt pivot and the rear suspension mount must comply with the specific-
ations given in Figure 16. Should this not be possible, the counter chassis profiles must be larger than normal and additional stiffen-
ing must be applied to the rear.
The position of the lift system must be defined with particular attention to protect the structural integrity of the rams and permit
a precise and practically location for the mountings The ram should preferably be situated in the most practical position available
ahead of the centre of gravity of the combined body and payload in order to reduce localised load.
The body builder must equip the vehicle appropriately to ensure stability during bed tilting manoeuvres.
All equipment and structures must comply with any applicable national legislation.
3.11 VEHICLES FOR COUNCIL, FIRE SERVICE AND SPECIAL USES
The outfitting of vehicles for municipal use (compactor trucks, road rollers; road cleaning vehicles) in many cases require:
●
the realization of a particularly robust counter chassis towards the rear and elastic type connections to the chassis towards the
front of the vehicle;
●
shortening of the rear overhang of the chassis.
When very short overhangs are necessary, the chassis may be shortened immediately downstream of the rear spring support
(or after the bar coupling in the case of air suspension), thus keeping intact the connection to the chassis of the crossbar ap-
plied therein;
●
the vertical placement of the exhaust, behind the cab;
●
the adoption of rear suspensions with greater rigidity (see Chapter 2.11 (
➠
Page 34));
●
a new arrangement of the rear lights.
▶
Do not use the reversing light switch, mounted on the gearbox, to activate functions that
require increased reliability and safety levels, (e.g. engine stop during reverse, on vehicles for
urban waste collection from the personnel present on the rear footboards).
3.12 FRONT INSTALLATION OF SNOW PLOUGH ATTACHMENTS
The application of a snowplough attachment (blade or ploughshare) to the front part of the vehicle must be carried out using a
suitable support structure, appropriately anchored to the core of the chassis side members and in observance of the prescriptions
contained in Chapter 2.2 (
➠
Page 8).
Since, when used to remove snow, the vehicle is weighted at the rear and the maximum speed is limited (e.g. 40 km/h), a small
increase in maximum axle load may be allowed upon specific assessment and authorisation by IVECO.
It should be possible to use all the elements of the vehicle front panel (e.g. tow-bar, supports for windscreen cleaner); otherwise,
equivalent systems must be provided in compliance with the safety requirements.
Observance of the required load must be documented and guaranteed by the company that carries out the installation.
