This category includes heavy-duty Iris guide units mounted on motorized positioning stands for larger product dimensions and demanding cable handling applications. The Iris provides symmetrical product guiding by means of four mechanically linked roller assemblies. Roller dimensions, materials and working range are selected according to the application. The Iris assembly is mounted on a stand providing motorized vertical height adjustment and motorized horizontal traverse, allowing the complete guide unit to be positioned and aligned with the required product centerline. Travel ranges, Iris working range, roller specification, control system and other application-specific details are defined on the individual drawings.
