The roller wheel tower features a plate cam drive fixed on the input shaft, with a design incorporating parallel conjugate cams. It achieves the function of dividing the output shaft by rotating the roller wheel tower through the rotation of two plate cams mounted on the input shaft. Suitable for driving wider conveyor belts or for intermittent indexing with longer dwell times. Additionally, the three-piece heavy-duty model is better suited for rapid conveyance over longer intervals, with a longer dwell time compared to the two-piece design.
