The bending moment on the chassis can be calculated using the formula below:
M [Nm] = W
L
x A + W
TL
x B for tail lifts without stabilizers
M [Nm] = W
L
x C + W
TL
x D for tail lifts with stabilizers
As mentioned, in order to decrease the elastic sagging of the chassis, which cannot be avoided when using a tail lift, use reinforcing
profiles with Wx resistance modulus of a higher value than the minimum values shown in Table 3.11.
This is even more valid for high and non standard overhangs, where the need of using stabilizers must in any case be checked (see
Figure 3.22).
According to the capacity of the tail lift, take into account the stability and trim of the vehicle deriving
from the sagging of the suspensions and chassis during the operation of the tail lift. Therefore, always
assess if it is necessary to use stabilizers, even when it would not be required taking into account only
the stress generated on the chassis.
!
Stabilizers must be fixed to the support structure of the tail lift and must be preferably hydraulically operated.
Stabilizers must be operated under all loading conditions of the tail lift.
!
When installing electro-hydraulic tail lifts, check that the batteries have a sufficient capacity and the alternator power (see paragraph
5.4).
IVECO requires fittings a switch isolating the electric circuit of the tail lift from the vehicle circuit when the tail lift is not operating.
Furthermore, the Bodybuilder must take care of any modification of the underrun bar or the placing of a new type of cross member
(see paragraph 2.19) as well as respecting the visibility of rear lights, overhang angles and positioning of the towing hook, as established
by the relative national regulations.
In van versions, lifters with a capacity up to 3 kN (300 kg) can be applied after installing local reinforcements on the chassis; greater
capacities must be assessed from time to time.
