multitwist boom
The JOSKIN Multitwist multi-nozzle spreading booms allow
to spread slurry over a large width (12 to 24 m), close to the
ground, under the form of ‘‘umbrella-like’’ jets.
This spreading tool is made up of two main pipes supported by
two triangular frames. In the 12 m version, the two main pipes
feed each of the four nozzles ended by vanes.
The slurry transfer circuit starts at a collector, which distributes
the slurry coming from the tank through two rubber flexible pipes
(Ø 125 mm). These pipes bring slurry in a straight line to the middle
of each main pipe, so that the flow is not slackened and the
pressure is optimal and uniform on each spreading nozzle.
The projection system mounted at the end of each smaller nozzle
is made of a rubber cone directed to a circular deflector. A rear
plate ensures an even spreading.
A quick opening cap, fixed on the outer ends of the main nozzles,
allows to clean easily and quickly.
The JOSKIN Multitwist boom is usually fixed to galvanized
cross-pieces (with height adjustment), but can also be mounted
on a 4-point linkage.
The advantages of the Multitwist spreading boom
are: large spreading width, ease of use, even distribution
of slurry on the ground. The projection height
(50 - 60 cm) ensures a very low wind resistance and
contributes to the uniformity of the spreading pattern.
For a clean transport, without slurry losses, the Twist
system allows a 150° rotation of the boom.
Besides this anti-drip function, the Twist system has other advantages:
• it makes the linkage ‘‘secondary’’
• it offers a limited overhang
• it allows, in option, to spread with an exact scatterer without
having to take off the boom The macerator, as well as two
manual or hydraulic valves, have just to be added on the distribution
box.
The JOSKIN
Multitwist boom is fitted
with a hydraulic
folding system. The
articulating points of
the boom has been
designed in such a
way that their transport
width does not
exceed 3 metres.
During transport, the
whole is fastened by
a boom clipping system.
This system has a height adjustment system and a craddle
with a damping rubber.
Another safety that can turn out to be very useful in certain conditions
is the anti-crash safety system.
This system is standard mounted on all
Multitwist booms and consists in
fitting each boom wing with an articulation
and stay springs. In this
way, when spreading on a bumpy
ground, the ends of the boom will
retract (max. 55 cm) when hitting
the ground. Mounting the wings at
the end of the oblong holes allows them to pivot and to go back
to their initial position.
