Penditwist boom General points From an agronomic point of view, the JOSKIN Penditwist line spreading boom is very interesting as it makes it possible to lay slurry at the foot of the plants without slowing down on the ground of the vegetation and with no slurry residue in the forage (essential for grass and maize silage). Moreover, because it is manufactured in fully galvanized steel, it offers very interesting durability characteristics. The machine is made up of a triangular structure articulated on a central frame and supporting line spreading hoses that are fixed at regular intervals (250 or 300 mm according to the type of boom). The working principle of the Penditwist boom is very simple. Coming from the tank, the slurry goes through one (two) macerator(s) before flowing into the pipes and being softly laid down on the ground. Macerator The macerator is of utmost importance in order to make sure the Penditwist works properly. The 9 m booms have one single macerator while the booms from 12 m have two of them, in order to get a greater reactivity at the beginning of the spreading phase and to reduce the load losses (slurry is more uniformly spread). The macerators of the Penditwist are vertical and have horizontal outlets allowing to place the pipes in an optimal way. As a result, the load losses are limited and slurry is more homogeneously distributed, even at the end of a 18 m boom. The advantage of vertical macerators is their small overall dimensions. The total height of the boom is therefore limited. An electric reverser on macerator is standard mounted on each model, with a purpose-made control in the tractor cabin (see details page 8). Control of the hydraulic functions The simplified hydraulic control of the boom is ensured by the Easymatic sequential block operating the start of the macerator(s) as well as the linkage. Hitching The JOSKIN Penditwist booms are standard fitted with linking cross-pieces allowing the height adjustment. These cross-pieces are then hitched to the JOSKIN 4-point linkage of the spreader. Hydraulic folding All booms are fitted with the hydraulic folding system and the Twist system. This last allows to obtain the best anti-drip system ever. The Twist system turns the line spreading hoses completely over, thereby avoiding any loss of slurry on the road while helping to protect the environment. Other advantage of the Twist system: the line spreading hoses are pointed backwards and smootly lay slurry down without splashing (see photos page 23). The completely folded boom has an insignificant overhang that does not affect at all the driving of the carriage. The hydraulic folding system has the following parameters: • hydraulic safety device • locking of the boom wings in transport position thanks to interlocking supports • rams positioned askew (not vertically) to better hold the boom in position (reduction of the swinging movement) For the wide spreading booms, there is a double hydraulic folding system, significantly reducing the bulk along the tank (in option on 15 m and standard on 18 m). For higher safety, the folded boom is such that the position of the macerators is pointed inwards so as not to exceed the boom size. Moreover, each boom is standard fitted with an anti-crash safety system allowing a potential boom deflection of 55 cm in case it woud come into contact with an obstacle. Traditional spreading Provided your slurry tanker is equipped with the option ‘‘Exact scatterer through linkage’’, it is always possible to spread in a traditional way. Thanks to the height adjustment by means of the cross-pieces, it is not necessary to remove the boom to spread in sheets. -22-
