APPARATUS AND METHOD FOR ALIGNING BELT CONVEYOR COMPONENTS SUCH AS IDLER FRAMES AND PULLEYS

摘要

Apparatus and method of aligning idler frames of a belt conveyor. An optical square and a first line of sight indicator are mounted on the respective idler frame. The optical square provides a direct line of sight and an indirect line of sight perpendicular to the direct line of sight. One of the lines of sight extends along the idler frame and the other extends along the conveyor. A second line of sight indicator is located at a position along the conveyor from the idler frame and is displaced from the center line of the conveyor to the same extent as the optical square. The two sight indicators are then viewed through the optical square and the idler frame moved to bring them into apparent alignment.
