Abstract
Apparatus is provided for support of a self-sealing door on a horizontal coke oven and for guiding installation of the door on the oven. A single pair of hangers are provided for attachment to the oven adjacent opposite vertical sides of the door opening. At least one axially rotatable member is mounted on the door for engaging the hangers and providing movement of the door therealong in a horizontal direction toward the oven. The axially rotatable member is located in a position on the door so that the door will be suspended in a completely vertical attitude on the hangers and may then be rolled into contact with the frame at repeatable, accurate positions to obtain better sealing.
