Multi-Nozzle Booms
The JOSKIN Multitwist multi-nozzle booms enable the slurry to be spread evenly over widths of 12 and 15 m. This spreading implement consists of two main pipes (Ø 125 mm) supported by triangular frames. Each of them has distributor pipes with a 1.50 m spacing. Each of these has a splash plate at its end, which lays the slurry close to the ground in the form of "umbrella mats". This considerably reduces the wind uptake when spreading as well as ammonia losses.
The Multitwist boom is a very economical and simple solution for quality spreading over working widths of 12 and 15 metres. It has a simple structure with a low tare weight and a reduced purchase price. It is protected by hot-dip galvanisation, making it durable over time and insensitive to the circumstances of the working environment.
The slurry is first fed out of the tanker into a large-volume distribution box. This has a deflector plate which separates the slurry from any foreign bodies and then divides it into two equal proportions. The deflector plate, acting as a stone collection system, deflects the foreign bodies to a quick outlet to allow them to be discharged evenly. The slurry then leaves this box through Ø 125 mm rigid pipes and is finally conveyed in a direct line to the distribution heads. This box also has a 6" flanged straight outlet as standard which allows, for example, the fitting of an exact scatterer (optional) to fertilise areas narrower than the standard Multitwist boom spreading width.
The spreading pipes are fitted with adjustable splash plates. This means that the shape and horizontality of the "umbrella mat" can be adjusted to the viscosity of the material to be spread. It is therefore always possible to achieve a homogeneous distribution, regardless of the nature of the liquid product.
All spreading booms are fitted with the hydraulic folding system, which has an insignificant overhang and does not affect at all the driving of the carriage. During transport, the whole is secured by a boom clipping system that has a height adjustment device and a craddle with a shock absorbing rubber. The hydraulic folding rams are positioned at an angle, and not vertically, to better hold the boom in position (reduction of the swinging movement). The Multitwist is fitted with the "Twist" anti-drip system (JOSKIN patent - 150° rotation) which allows the spreading pipes to be positioned vertically for transport, thus avoiding accidental loss of slurry during your journeys on public roads. The wings of the JOSKIN spreading booms are equipped as standard with the anti-crash device and the fitting of the anti-drip hydraulic ram ends on oblongs. This system allows the wings to pivot if the boom comes into contact with the ground (e.g. on a slope) and to level it.
The Multitwist boom is available in a "fixed bolted" version for tankers without rear linkage, as well as in a “linkage” version for tankers that have one, which is often the case for agricultural contractors who have to change of spreading implements according to customer wishes. The boom is also available as an add-on for any existing JOSKIN slurry tanker or made by another manufacturer.
