The roller wheel tower features a cam drive with two plates fixed to the input shaft, designed with parallel conjugate cams. It achieves the function of dividing the output shaft by rotating the roller wheel tower through the rotation of the two plate-type cams mounted on the input shaft, suitable for larger pitch conveyor drives or for intermittent indexing with longer dwell times. Additionally, the three-piece heavy-duty design is more suitable for rapid and long-pitch conveyances, with a longer dwell time compared to the two-piece design.
