ABSTRACT:
A method and apparatus for spotting a pusher machine or other door-handling machine in relation to a coke oven. The method and apparatus are particularly useful for aligning a door extractor carrying a door with an open hot oven, but also may be used to align a pusher ram. The apparatus includes left and right heat or light sensitive detectors at opposite sides of the part to be aligned with the oven and aimed at oblique angles toward the extended center line of the part. When both detectors are actuated simultaneously, the part is aligned accurately with the oven.
