Designed with right-hand and left-hand threads, with the exception of a few millimetres in the centre of the leadscrew, the entire length can be used for the stroke. This innovative leadscrew design also helps reduce costs where a second leadscrew is not required. The shuttle system can thus be used both for one- and two-sided parcel retrieving, and provides extra flexibility to handle boxes of various sizes.
Matching lubricant-free nuts with right-hand and left-hand threads are also available.
