Abstract: A safety gate has: a structural frame including a pair of columns spaced from one another along a peripheral edge of an elevated platform to define a ledge entrance to a staging area of the elevated platform; a ledge gate; and a staging gate; and in which the ledge gate and the staging gate are connected to move together relative to the pair of columns: into a loading configuration when the ledge gate rises and pitches upward, and the staging gate lowers and unfolds laterally away from the pair of structural columns, to allow a) the ledge gate to open the ledge entrance and b) the staging gate to enclose the staging area; and into an unloading configuration when the ledge gate lowers and pitches downward, and the staging gate rises and folds laterally toward the pair of structural columns, to allow a) the ledge gate to close the ledge entrance and b) the staging gate to expose the staging area.
