ABSTRACT OF THE DISCLOSURE A plate welded to what is the leading edge of the slide gate door, as the slide gate door would move in the opening direction, engages a portion of the peripheral face of a cam. The plate is above the supports on which the gate rides. In the event that a force is applied to the door urging the door in the opening direction, that portion of the cam cams the distal side of the plate toward those sup- ports, whereby the plate acts as a spring resisting that force and in preventing the door significantly moving in the opening direction. The cam can be rotated to another posi- tion at which the plate and door are free to move below it to the opened position.
