The new PrimeTracker works unlike conventional belt guidance systems. Due to its unique design, it acts like a standard conveyor belt roller when the belt runs smoothly and only intervenes when the belt leaves its optimum position. The PrimeTracker responds before the guide roller tilts horizontally. As soon as the conveyor belt runs off-centre, the PrimeTracker corrects the movement with small forces and very low friction, thus preventing unnecessary wear.
