3.16 CONCRETE MIXER INSTALLATION
Concrete mixer applications may only be constructed on vehicles that are suitable for this application and indicated in Table 3.16,
which provides the minimum specifications of the reinforcement sections and the effective capacity of the drum. The maximum
permissible weights for these vehicles may not be exceeded.
For the actual installation, besides observing the prescriptions imposed by the national Standards, the following also applies:
●
The concrete mixer must be equipped with a continuous steel counter chassis, in order to distribute concentrated loads as
much as possible. The chassis members may consist of sections which, while ensuring the same section modulus (W
x
) and a
moment of inertia (J
x
) not less than the values given in Table 3.15, make it possible to lower the centre of gravity of the added
structure (e.g. box sections, or sections with upper wing turned outwards, see Figure 3.28.

●
The counter chassis must be reinforced (e.g. crossbar, cross brace at rear part - see Chapter 3.2 - Paragraph "Crossbars"
(
➠
Page 9)) to reduce stress on the vehicle chassis caused by the forces generated during vehicle operation (due to the spe-
cific geometric configuration of the structure).
●
The connections (see Chapter 3.3 (
➠
Page 11)) must only involve the two chassis and be realized so as to guarantee secure
anchoring. For vehicles not originally equipped with plates, the use of plates is recommended for transverse and longitudinal
containment, while elastic connections should be limited to the front end of the counter chassis (see Figure 3.11 and 3.28).
