3-46 BUILDING & MOUNTING THE STRUCTURES E UROCARGO Euro 4/5 - the mounting (see point 3.3) must affect only the two frames and must be constructed in such a manner as to provide a secure anchorage.
For those vehicles which are not yet equipped with them, we recommend the use of cleat plates to avoid slippage in length or to the side, restricting the use of flexible joints to the front end of the subframe (see Figure 3.28); Figure 3.28 91533 1 Subframe 2 Brackets 3 Cleat plates - when installing the cement mixer assembly, care must be taken to position the centre of gravity as close to the front axle as possible, obviously with due consideration to the maximum permissible weight on the axle itself.
To obtain the necessary stability of the vehicle and its safety while in operation, particularly when cornering or on rough terrain with transverse and/or longitudinal slope, the swing effect of the payload inside the drum must be taken into consideration since it results in a shift of the dynamic centre of gravity of the payload and consequently it adversely affects the vehicle’s behaviour; - specific PTO solutions are available on request that are independent of the clutch and suitable for concrete mixer applications (see point 4.5.2).
The auxiliary motor to control the drum must be mounted on an appropriate elastic suspension; - due to rotation of the drum the centre of gravity of the load moves and therefore the differences in the trasverse load must be kept within acceptable limits.
