The Jervis Webb 8702 4″ Anti Back-up Device is the optimal safety solution for your production needs. 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.
