  • the conveyance of elongated, rod-shaped, stick-shaped or stalk-shaped material to be conveyed is required, for example, in the area of conveying cuttings and is usually particularly difficult if elongated or rod-shaped cuttings / material cannot be transported or conveyed in any position, but is to be transported aligned in a defined position over the conveyor line.
  • Link chains require relatively intensive maintenance and lubrication, are relatively heavy because they are made of metal and can occasionally be problematic with regard to noise emissions.

Even if the harvested crop is conveyed here without any problems by several conveyor elements / link chains running in parallel, it would still be desirable to achieve a weight saving and a reduction in maintenance intervals.

This enables the stalk-like cuttings to be transported safely and with a "grip". The spaces between the drivers are reduced by the mutual engagement and the conveyed goods are securely held.
