Abstract
A silo door structure having a ladder rung assembly on which the door is supported, the rung assembly including vertical pivot pin extensions received within vertical apertures formed in the top and bottom cross beams of the door frame. The weight of the door and ladder rung assembly is transmitted to the door frame through the pivot pin extensions as well as through offset, generally horizontal segments on the bottom end of the ladder rung assembly which rests on the bottom sill beam of the door frame when the door is closed. A locking bar swingably mounted on the door is held in tight engagement with the outside face of the door frame by camming members on a pivotal clamp arm so as to draw the door in tightly against a sealing gasket plastered in place around the periphery of the door frame opening.
