Abstract
A double door gate apparatus having a frame, a main gate and a secondary gate. The outer ends of the main and secondary gates are pivotally mounted to the frame. The inner ends of the main and secondary gates confront each other and swing in both ways independently of the other. The main and secondary gates are openable independently of the other. Prior to being opened, each of the main and secondary gates is lifted upwardly on its respective pivot axis to be disengaged from the frame. Portions of the frame work as stops to signal that the main and secondary gates have been lifted sufficiently to be openable.
