4" Chain Anti Back-up Device, Part # 8702

4" Chain Anti Back-up Device, Part # 8702

Designed for 4” I-beam systems, these anti-backup devices prevent trolleys from rolling backwards on vertical inclines. Anti-backup stop arms are mechanically lifted by the passing trolley brackets as they ride up the incline. Should the power fail, the stop arms will provide a positive stop. Stop arms are equipped with rubber bumpers to reduce noise.
