World's Largest Round Vault Door

On the surface it would appear that the non-load-bearing hinges are as represented in the diagram. However, let's look at the Remington-Sherman US patent 793,703 (filed 1904):



As can be seen, the upper-right hinge in fact does support part of the load. The crane bears down on the journal 10, which in turn bears down on the housing attached to the vestibule (frame). This matches the configuration of One King West. I would have no doubt that the same configuration is used on the "other" hinge point at the Cleveland Fed. Proper installation would involve fiddling with the two adjustments to get the door height correct, and to distribute the load equally across both thrust bearings.
