Alignment Verification Rig
Idlers are equipped with slots allowing angular adjustment as needed for tracking but the optimum position perpendicular to the belt direction is uncertain.
Angular triangulation is tedious and requires two millwrights. More importantly, manufacturing variations in the idler frame and conveyor stringers mean conveyor and idler frames are not necessarily good for measuring points. The important components for precise angular location are the belt and the rolls, especially the center roll, but they are difficult to reference to each other.
