rante è un tutt’uno con l’albero di entrata del riduttore. Que-
st’ultimo ha alberi temprati, cementati e rettificati, che lavora-
no in bagno d’olio. Il tamburo è supportato da cuscinetti a te-
nuta ermetica esenti da lubrificazione e usura, a tutto vantag-
gio della riduzione degli attriti.
Terminali adacquatori
Con le lance a braccio oscillante la
massima versatilità viene ottenuta
tramite la possibilità di sostituire i
boccagli, in modo da ottenere la
frantumazione più adatta della vena
liquida in relazione alle caratteristi-
che del terreno e della coltura in at-
to. Viceversa, le ali piovane e le bar-
re irrigatrici hanno il vantaggio di la-
vorare a bassa pressione, con un ri-
sparmio energetico fino al 50% ri-
spetto alle lance a lunga gittata. In-
fatti, le nuove ali piovane in acciaio
zincato o alluminio sono in grado di
offrire coperture fino a 50 m per
passata, assicurando tra l’altro una
nebulizzazione ottimale dell’acqua.

Watering terminals
Maximum versatility with a lance on an oscillating boom is
achieved by the option to replace the mouthpieces to obtain
the atomization most suitable for the water flow in relation
to the characteristics of the soil and growth stage of crops.
On the other hand, sprinkler booms and irrigation bars have
the advantage of operating a low pressure to save energy by
up to 50% compared to the long jet lance. In fact, new sprin-
kler booms in galvanized steel or aluminum are capable of
coverage at distances of up to 50 m with each pass while op-
timizing the atomization of the water.
Hydraulic servo control
The application of hydraulic movement servo mechanisms
on reels has make it possible for the operator to easily man-
age the machine, often by remote control via ratio. Examples
are opening the traveling cart gate and/or raising the irriga-
tion bar for changing location, rotating the swivel supporting
the hose, placing and anchoring equipment and placing the
suction pipe on models with a pump.
CPU management and control
A battery powered CPU sometimes integrated with a photo-
voltaic solar panel makes it possible to complete automation
of irrigation operations beginning with control of flow and the
speed of work on to programming the timing for beginning ir-
rigation and finishing for correct watering without moving the
components. Among the various solutions offered, Casella
markets the Hydro-Control 260 CPU, which can be equipped
with a GSM module. This means the computer can regulate
the starting watering time without rewind and opens and clos-
es the water flow to carry out watering in the correct way and
change the pre-programmed parameters during watering.
Moreover, the Hydro-Control provides a switchboard start key
for functions which include total monitoring of the parame-
ters and the performance of the pump. For fertigation, an-
other CPU is available for injecting liquid fertilizer on the pump
suction and allows splitting the doses to avoid losses.
