A safety gate to be mounted on a loading dock. The safety gate includes a pair of vertical columns which are mounted on the floor of the dock on either side of a doorway that can be enclosed by an overhead door. A barrier or beam is mounted for sliding movement on the vertical columns and can be moved from an upper storage position where it is located above the doorway to a lower operative position where it extends across the doorway and will prevent material handling equipment, or other objects from accidentally passing through the doorway and falling to the driveway adjacent the dock. The barrier is composed of a pair of elongated side members which are connected by a pair of end members and a series of spaced transverse members. Each column is disposed in the space between an end member and the adjacent transverse member, and the outer surface of one of the side members facing the dock is provided with a resilient shock absorbing layer. The weight of the barrier is counterbalanced by a pair of counterweights that move within the hollow vertical columns, and the barrier is held in the lower position by a releasable latch.
