JOSKIN booms (except the BASIC range) are all equipped as standard with the (double acting) anti-drip lifting device with Twist system. This ensures a clean transport thanks to a complete rotation of the line hose ends, which prevents any loss of slurry on the road and in the field during manoeuvres. In addition to the anti-drip function, the Twist system has other advantages: it offers a low overhang and, as an option, allows spreading with an exact scatterer without having to remove the boom. The scatterer and two manual or hydraulic valves to isolate it just have to be added.
The JOSKIN spreading booms (except the BASIC range) are all fitted as standard with an anti-crash safety device that provides extra safety when working on uneven ground. Each boom wing is equipped with springs and joints which, when spreading on bumpy ground, retract the ends of the boom (max. 80 cm) if they come into contact with the ground. Since the wings are fitted at the end of oblong holes, they can pivot and their height can be adjusted.
All spreading booms are equipped with a hydraulic folding system, which has a negligible overhang and does not affect the driving of the tractor-trailer combination. During transport, the whole is secured by a boom clipping system with a height adjustment device and a craddle with a shock absorbing rubber. The hydraulic folding system includes the following elements: hydraulic safety device, locking of the boom wings during transport by means of interlocking brackets and hydraulic rams positioned diagonally instead of vertically to better hold the boom in position (reduction of the swinging movement). For a higher safety, when the boom is folded, the macerators face inwards in order not to protrude beyond the boom structure.
The JOSKIN MULTITWIST multi-nozzle booms spread the slurry evenly over widths of 12 and 15 m. This spreading implement consists of two main pipes supported by two triangular frames. These main pipes feed half of the smaller vertical pipes on the boom, each of which is terminated by a splash plate. The slurry is then spread close to the ground, under the form of '“umbrella'' jets. It should be noted that an installation on the 4-point linkage as well as directly on the buttresses of the tank is possible with the Twist system.
