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.

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.
