A novel dockplate is made up of three pieces hinge-connected together to form a safe bridging means. The end pieces or plates of the three-piece structure have breaks to permit a minimum angle incline when the dockplate is in use. The center or main portion of the dockplate has a base which lifts it above the upper planes of both end pieces.
